Future<AssumeRoleResult> assumeRoleAsync(AssumeRoleRequest assumeRoleRequest)
Returns a set of temporary security credentials that you can use to access Amazon Web Services resources. These
temporary credentials consist of an access key ID, a secret access key, and a security token. Typically, you use
AssumeRole
within your account or for cross-account access. For a comparison of
AssumeRole
with other API operations that produce temporary credentials, see Requesting Temporary
Security Credentials and Comparing the Amazon Web Services STS API operations in the IAM User Guide.
Permissions
The temporary security credentials created by AssumeRole
can be used to make API calls to any Amazon
Web Services service with the following exception: You cannot call the Amazon Web Services STS
GetFederationToken
or GetSessionToken
API operations.
(Optional) You can pass inline or managed session policies to this operation. You can pass a single JSON policy document to use as an inline session policy. You can also specify up to 10 managed policy Amazon Resource Names (ARNs) to use as managed session policies. The plaintext that you use for both inline and managed session policies can't exceed 2,048 characters. Passing policies to this operation returns new temporary credentials. The resulting session's permissions are the intersection of the role's identity-based policy and the session policies. You can use the role's temporary credentials in subsequent Amazon Web Services API calls to access resources in the account that owns the role. You cannot use session policies to grant more permissions than those allowed by the identity-based policy of the role that is being assumed. For more information, see Session Policies in the IAM User Guide.
When you create a role, you create two policies: a role trust policy that specifies who can assume the role, and a permissions policy that specifies what can be done with the role. You specify the trusted principal that is allowed to assume the role in the role trust policy.
To assume a role from a different account, your Amazon Web Services account must be trusted by the role. The trust relationship is defined in the role's trust policy when the role is created. That trust policy states which accounts are allowed to delegate that access to users in the account.
A user who wants to access a role in a different account must also have permissions that are delegated from the
account administrator. The administrator must attach a policy that allows the user to call
AssumeRole
for the ARN of the role in the other account.
To allow a user to assume a role in the same account, you can do either of the following:
Attach a policy to the user that allows the user to call AssumeRole
(as long as the role's trust
policy trusts the account).
Add the user as a principal directly in the role's trust policy.
You can do either because the role’s trust policy acts as an IAM resource-based policy. When a resource-based policy grants access to a principal in the same account, no additional identity-based policy is required. For more information about trust policies and resource-based policies, see IAM Policies in the IAM User Guide.
Tags
(Optional) You can pass tag key-value pairs to your session. These tags are called session tags. For more information about session tags, see Passing Session Tags in STS in the IAM User Guide.
An administrator must grant you the permissions necessary to pass session tags. The administrator can also create granular permissions to allow you to pass only specific session tags. For more information, see Tutorial: Using Tags for Attribute-Based Access Control in the IAM User Guide.
You can set the session tags as transitive. Transitive tags persist during role chaining. For more information, see Chaining Roles with Session Tags in the IAM User Guide.
Using MFA with AssumeRole
(Optional) You can include multi-factor authentication (MFA) information when you call AssumeRole
.
This is useful for cross-account scenarios to ensure that the user that assumes the role has been authenticated
with an Amazon Web Services MFA device. In that scenario, the trust policy of the role being assumed includes a
condition that tests for MFA authentication. If the caller does not include valid MFA information, the request to
assume the role is denied. The condition in a trust policy that tests for MFA authentication might look like the
following example.
"Condition": {"Bool": {"aws:MultiFactorAuthPresent": true}}
For more information, see Configuring MFA-Protected API Access in the IAM User Guide guide.
To use MFA with AssumeRole
, you pass values for the SerialNumber
and
TokenCode
parameters. The SerialNumber
value identifies the user's hardware or virtual
MFA device. The TokenCode
is the time-based one-time password (TOTP) that the MFA device produces.
assumeRoleRequest
- Future<AssumeRoleResult> assumeRoleAsync(AssumeRoleRequest assumeRoleRequest, AsyncHandler<AssumeRoleRequest,AssumeRoleResult> asyncHandler)
Returns a set of temporary security credentials that you can use to access Amazon Web Services resources. These
temporary credentials consist of an access key ID, a secret access key, and a security token. Typically, you use
AssumeRole
within your account or for cross-account access. For a comparison of
AssumeRole
with other API operations that produce temporary credentials, see Requesting Temporary
Security Credentials and Comparing the Amazon Web Services STS API operations in the IAM User Guide.

Add the user as a principal directly in the role's trust policy.
You can do either because the role’s trust policy acts as an IAM resource-based policy. When a resource-based policy grants access to a principal in the same account, no additional identity-based policy is required. For more information about trust policies and resource-based policies, see IAM Policies in the IAM User Guide.

(Optional) You can pass tag key-value pairs to your session. These tags are called session tags. For more information about session tags, see Passing Session Tags in STS in the IAM User Guide.
An administrator must grant you the permissions necessary to pass session tags. The administrator can also create granular permissions to allow you to pass only specific session tags. For more information, see Tutorial: Using Tags for Attribute-Based Access Control in the IAM User Guide.

TokenCode
parameters. The SerialNumber
value identifies the user's hardware or virtual
MFA device. The TokenCode
is the time-based one-time password (TOTP) that the MFA device produces.
assumeRoleRequest
- asyncHandler
- Asynchronous callback handler for events in the lifecycle of the request. Users can provide an
implementation of the callback methods in this interface to receive notification of successful or
unsuccessful completion of the operation.Future<AssumeRoleWithSAMLResult> assumeRoleWithSAMLAsync(AssumeRoleWithSAMLRequest assumeRoleWithSAMLRequest)
Returns a set of temporary security credentials for users who have been authenticated via a SAML authentication
response. This operation provides a mechanism for tying an enterprise identity store or directory to role-based
Amazon Web Services access without user-specific credentials or configuration. For a comparison of
AssumeRoleWithSAML
with the other API operations that produce temporary credentials, see Requesting Temporary
Security Credentials and Comparing the Amazon Web Services STS API operations in the IAM User Guide.
The temporary security credentials returned by this operation consist of an access key ID, a secret access key, and a security token. Applications can use these temporary security credentials to sign calls to Amazon Web Services services.
Session Duration
By default, the temporary security credentials created by AssumeRoleWithSAML
last for one hour.
However, you can use the optional DurationSeconds
parameter to specify the duration of your session.
Your role session lasts for the duration that you specify, or until the time specified in the SAML authentication
response's SessionNotOnOrAfter
value, whichever is shorter. You can provide a
DurationSeconds
value from 900 seconds (15 minutes) up to the maximum session duration setting for
the role. This setting can have a value from 1 hour to 12 hours. To learn how to view the maximum value for your
role, see View
the Maximum Session Duration Setting for a Role in the IAM User Guide. The maximum session duration
limit applies when you use the AssumeRole*
API operations or the assume-role*
CLI
commands. However the limit does not apply when you use those operations to create a console URL. For more
information, see Using IAM Roles
in the IAM User Guide.
Role chaining limits your CLI or Amazon Web Services API role session to a maximum of one hour. When you use
the AssumeRole
API operation to assume a role, you can specify the duration of your role session
with the DurationSeconds
parameter. You can specify a parameter value of up to 43200 seconds (12
hours), depending on the maximum session duration setting for your role. However, if you assume a role using role
chaining and provide a DurationSeconds
parameter value greater than one hour, the operation fails.
Permissions
The temporary security credentials created by AssumeRoleWithSAML
can be used to make API calls to
any Amazon Web Services service with the following exception: you cannot call the STS
GetFederationToken
or GetSessionToken
API operations.
(Optional) You can pass inline or managed session policies to this operation. You can pass a single JSON policy document to use as an inline session policy. You can also specify up to 10 managed policy Amazon Resource Names (ARNs) to use as managed session policies. The plaintext that you use for both inline and managed session policies can't exceed 2,048 characters. Passing policies to this operation returns new temporary credentials. The resulting session's permissions are the intersection of the role's identity-based policy and the session policies. You can use the role's temporary credentials in subsequent Amazon Web Services API calls to access resources in the account that owns the role. You cannot use session policies to grant more permissions than those allowed by the identity-based policy of the role that is being assumed. For more information, see Session Policies in the IAM User Guide.
Calling AssumeRoleWithSAML
does not require the use of Amazon Web Services security credentials. The
identity of the caller is validated by using keys in the metadata document that is uploaded for the SAML provider
entity for your identity provider.
Calling AssumeRoleWithSAML
can result in an entry in your CloudTrail logs. The entry includes the
value in the NameID
element of the SAML assertion. We recommend that you use a
NameIDType
that is not associated with any personally identifiable information (PII). For example,
you could instead use the persistent identifier (
urn:oasis:names:tc:SAML:2.0:nameid-format:persistent
).
Tags
(Optional) You can configure your IdP to pass attributes into your SAML assertion as session tags. Each session tag consists of a key name and an associated value. For more information about session tags, see Passing Session Tags in STS in the IAM User Guide.
You can pass up to 50 session tags. The plaintext session tag keys can’t exceed 128 characters and the values can’t exceed 256 characters. For these and additional limits, see IAM and STS Character Limits in the IAM User Guide.
An Amazon Web Services conversion compresses the passed inline session policy, managed policy ARNs, and session
tags into a packed binary format that has a separate limit. Your request can fail for this limit even if your
plaintext meets the other requirements. The PackedPolicySize
response element indicates by
percentage how close the policies and tags for your request are to the upper size limit.
You can pass a session tag with the same key as a tag that is attached to the role. When you do, session tags override the role's tags with the same key.
An administrator must grant you the permissions necessary to pass session tags. The administrator can also create granular permissions to allow you to pass only specific session tags. For more information, see Tutorial: Using Tags for Attribute-Based Access Control in the IAM User Guide.
You can set the session tags as transitive. Transitive tags persist during role chaining. For more information, see Chaining Roles with Session Tags in the IAM User Guide.
SAML Configuration
Before your application can call AssumeRoleWithSAML
, you must configure your SAML identity provider
(IdP) to issue the claims required by Amazon Web Services. Additionally, you must use Identity and Access
Management (IAM) to create a SAML provider entity in your Amazon Web Services account that represents your
identity provider. You must also create an IAM role that specifies this SAML provider in its trust policy.

- Asynchronous callback handler for events in the lifecycle of the request. Users can provide an
implementation of the callback methods in this interface to receive notification of successful or
unsuccessful completion of the operation.Future<AssumeRoleWithWebIdentityResult> assumeRoleWithWebIdentityAsync(AssumeRoleWithWebIdentityRequest assumeRoleWithWebIdentityRequest)
Returns a set of temporary security credentials for users who have been authenticated in a mobile or web application with a web identity provider. Example providers include the OAuth 2.0 providers Login with Amazon and Facebook, or any OpenID Connect-compatible identity provider such as Google or Amazon Cognito federated identities.
For mobile applications, we recommend that you use Amazon Cognito. You can use Amazon Cognito with the Amazon Web Services SDK for iOS Developer Guide and the Amazon Web Services SDK for Android Developer Guide to uniquely identify a user. You can also supply the user with a consistent identity throughout the lifetime of an application.
To learn more about Amazon Cognito, see Amazon Cognito identity pools in Amazon Cognito Developer Guide.
Calling AssumeRoleWithWebIdentity
does not require the use of Amazon Web Services security
credentials. Therefore, you can distribute an application (for example, on mobile devices) that requests
temporary security credentials without including long-term Amazon Web Services credentials in the application.
You also don't need to deploy server-based proxy services that use long-term Amazon Web Services credentials.
Instead, the identity of the caller is validated by using a token from the web identity provider. For a
comparison of AssumeRoleWithWebIdentity
with the other API operations that produce temporary
credentials, see Requesting Temporary
Security Credentials and Comparing the Amazon Web Services STS API operations in the IAM User Guide.
The temporary security credentials returned by this API consist of an access key ID, a secret access key, and a security token. Applications can use these temporary security credentials to sign calls to Amazon Web Services service API operations.
Session Duration
By default, the temporary security credentials created by AssumeRoleWithWebIdentity
last for one
hour. However, you can use the optional DurationSeconds
parameter to specify the duration of your
session. You can provide a value from 900 seconds (15 minutes) up to the maximum session duration setting for the

(Optional) You can pass inline or managed session policies to this operation. You can pass a single JSON policy document to use as an inline session policy. You can also specify up to 10 managed policy Amazon Resource Names (ARNs) to use as managed session policies. The plaintext that you use for both inline and managed session policies can't exceed 2,048 characters. Passing policies to this operation returns new temporary credentials. The resulting session's permissions are the intersection of the role's identity-based policy and the session policies.

You can set the session tags as transitive. Transitive tags persist during role chaining. For more information, see Chaining Roles with Session Tags in the IAM User Guide.
Identities
Before your application can call AssumeRoleWithWebIdentity
, you must have an identity token from a
supported identity provider and create a role that the application can assume. The role that your application
assumes must trust the identity provider that is associated with the identity token. In other words, the identity
provider must be specified in the role's trust policy.
Calling AssumeRoleWithWebIdentity
can result in an entry in your CloudTrail logs. The entry includes
the Subject of the provided web
identity token. We recommend that you avoid using any personally identifiable information (PII) in this field.
For example, you could instead use a GUID or a pairwise identifier, as suggested in the OIDC
specification.

You can also supply the user with a consistent identity throughout the lifetime of an application.
To learn more about Amazon Cognito, see Amazon Cognito identity pools in Amazon Cognito Developer Guide.
Calling AssumeRoleWithWebIdentity
does not require the use of Amazon Web Services security
credentials. Therefore, you can distribute an application (for example, on mobile devices) that requests
temporary security credentials without including long-term Amazon Web Services credentials in the application.
You also don't need to deploy server-based proxy services that use long-term Amazon Web Services credentials.
Instead, the identity of the caller is validated by using a token from the web identity provider. For a
comparison of AssumeRoleWithWebIdentity
with the other API operations that produce temporary
credentials, see Requesting Temporary
Security Credentials and Comparing the Amazon Web Services STS API operations in the IAM User Guide.
The temporary security credentials returned by this API consist of an access key ID, a secret access key, and a security token. Applications can use these temporary security credentials to sign calls to Amazon Web Services service API operations.
Session Duration
By default, the temporary security credentials created by AssumeRoleWithWebIdentity
last for one
hour. However, you can use the optional DurationSeconds
parameter to specify the duration of your
session. You can provide a value from 900 seconds (15 minutes) up to the maximum session duration setting for the
role. This setting can have a value from 1 hour to 12 hours. To learn how to view the maximum value for your
role, see View
the Maximum Session Duration Setting for a Role in the IAM User Guide. The maximum session duration
limit applies when you use the AssumeRole*
API operations or the assume-role*
CLI
commands. However the limit does not apply when you use those operations to create a console URL. For more
information, see Using IAM Roles
in the IAM User Guide.
Permissions
The temporary security credentials created by AssumeRoleWithWebIdentity
can be used to make API
calls to any Amazon Web Services service with the following exception: you cannot call the STS
GetFederationToken
or GetSessionToken
API operations.
(Optional) You can pass inline or managed session policies to this operation. You can pass a single JSON policy document to use as an inline session policy. You can also specify up to 10 managed policy Amazon Resource Names (ARNs) to use as managed session policies. The plaintext that you use for both inline and managed session policies can't exceed 2,048 characters. Passing policies to this operation returns new temporary credentials. The resulting session's permissions are the intersection of the role's identity-based policy and the session policies. You can use the role's temporary credentials in subsequent Amazon Web Services API calls to access resources in the account that owns the role. You cannot use session policies to grant more permissions than those allowed by the identity-based policy of the role that is being assumed. For more information, see Session Policies in the IAM User Guide.
Tags
(Optional) You can configure your IdP to pass attributes into your web identity token as session tags. Each session tag consists of a key name and an associated value. For more information about session tags, see Passing Session Tags in STS in the IAM User Guide.
You can pass up to 50 session tags. The plaintext session tag keys can’t exceed 128 characters and the values can’t exceed 256 characters. For these and additional limits, see IAM and STS Character Limits in the IAM User Guide.
An Amazon Web Services conversion compresses the passed inline session policy, managed policy ARNs, and session
tags into a packed binary format that has a separate limit. Your request can fail for this limit even if your
plaintext meets the other requirements. The PackedPolicySize
response element indicates by
percentage how close the policies and tags for your request are to the upper size limit.
You can pass a session tag with the same key as a tag that is attached to the role. When you do, the session tag overrides the role tag with the same key.
An administrator must grant you the permissions necessary to pass session tags. The administrator can also create granular permissions to allow you to pass only specific session tags. For more information, see Tutorial: Using Tags for Attribute-Based Access Control in the IAM User Guide.
You can set the session tags as transitive. Transitive tags persist during role chaining. For more information, see Chaining Roles with Session Tags in the IAM User Guide.
Identities
Before your application can call AssumeRoleWithWebIdentity
, you must have an identity token from a
supported identity provider and create a role that the application can assume. The role that your application
assumes must trust the identity provider that is associated with the identity token. In other words, the identity
provider must be specified in the role's trust policy.
Calling AssumeRoleWithWebIdentity
can result in an entry in your CloudTrail logs. The entry includes
the Subject of the provided web
identity token. We recommend that you avoid using any personally identifiable information (PII) in this field.
For example, you could instead use a GUID or a pairwise identifier, as suggested in the OIDC
specification.

- asyncHandler
- Asynchronous callback handler for events in the lifecycle of the request. Users can provide an
implementation of the callback methods in this interface to receive notification of successful or
unsuccessful completion of the operation.Future<DecodeAuthorizationMessageResult> decodeAuthorizationMessageAsync(DecodeAuthorizationMessageRequest decodeAuthorizationMessageRequest)
Decodes additional information about the authorization status of a request from an encoded message returned in response to an Amazon Web Services request.
For example, if a user is not authorized to perform an operation that he or she has requested, the request
returns a Client.UnauthorizedOperation
response (an HTTP 403 response). Some Amazon Web Services
operations additionally return an encoded message that can provide details about this authorization failure.
Only certain Amazon Web Services operations return an encoded authorization message. The documentation for an individual operation indicates whether that operation returns an encoded message in addition to returning an HTTP code.
The message is encoded because the details of the authorization status can contain privileged information that
the user who requested the operation should not see. To decode an authorization status message, a user must be
granted permissions through an IAM policy to request the
DecodeAuthorizationMessage
(sts:DecodeAuthorizationMessage
) action.
The decoded message includes the following type of information:
Whether the request was denied due to an explicit deny or due to the absence of an explicit allow. For more information, see Determining Whether a Request is Allowed or Denied in the IAM User Guide.
The principal who made the request.
The requested action.
The requested resource.
The values of condition keys in the context of the user's request.

- Asynchronous callback handler for events in the lifecycle of the request. Users can provide an
implementation of the callback methods in this interface to receive notification of successful or
unsuccessful completion of the operation.Future<GetAccessKeyInfoResult> getAccessKeyInfoAsync(GetAccessKeyInfoRequest getAccessKeyInfoRequest)
Returns the account identifier for the specified access key ID.
Access keys consist of two parts: an access key ID (for example, AKIAIOSFODNN7EXAMPLE
) and a secret
access key (for example, wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
). For more information about
access keys, see Managing Access Keys for
IAM Users in the IAM User Guide.
When you pass an access key ID to this operation, it returns the ID of the Amazon Web Services account to which
the keys belong. Access key IDs beginning with AKIA
are long-term credentials for an IAM user or the
Amazon Web Services account root user. Access key IDs beginning with ASIA
are temporary credentials
that are created using STS operations. If the account in the response belongs to you, you can sign in as the root
user and review your root user access keys. Then, you can pull a credentials report
to learn which IAM user owns the keys. To learn who requested the temporary credentials for an ASIA
access key, view the STS events in your CloudTrail logs in the
IAM User Guide.
This operation does not indicate the state of the access key. The key might be active, inactive, or deleted. Active keys might not have permissions to perform an operation. Providing a deleted access key might return an error that the key doesn't exist.
getAccessKeyInfoRequest
- Future<GetAccessKeyInfoResult> getAccessKeyInfoAsync(GetAccessKeyInfoRequest getAccessKeyInfoRequest, AsyncHandler<GetAccessKeyInfoRequest,GetAccessKeyInfoResult> asyncHandler)

access keys, see Managing Access Keys for
IAM Users in the IAM User Guide.
When you pass an access key ID to this operation, it returns the ID of the Amazon Web Services account to which
the keys belong. Access key IDs beginning with AKIA
are long-term credentials for an IAM user or the
Amazon Web Services account root user. Access key IDs beginning with ASIA
are temporary credentials
that are created using STS operations. If the account in the response belongs to you, you can sign in as the root

Returns details about the IAM user or role whose credentials are used to call the operation.
No permissions are required to perform this operation. If an administrator attaches a policy to your identity
that explicitly denies access to the sts:GetCallerIdentity
action, you can still perform this
operation. Permissions are not required because the same information is returned when access is denied. To view
an example response, see I Am Not Authorized to Perform: iam:DeleteVirtualMFADevice in the IAM User Guide.

Returns a set of temporary security credentials (consisting of an access key ID, a secret access key, and a security token) for a user. A typical use is in a proxy application that gets temporary security credentials on behalf of distributed applications inside a corporate network.
You must call the GetFederationToken
operation using the long-term security credentials of an IAM
user. As a result, this call is appropriate in contexts where those credentials can be safeguarded, usually in a
server-based application. For a comparison of GetFederationToken
with the other API operations that
produce temporary credentials, see Requesting Temporary
Security Credentials and Comparing the Amazon Web Services STS API operations in the IAM User Guide.
Although it is possible to call GetFederationToken
using the security credentials of an Amazon Web
Services account root user rather than an IAM user that you create for the purpose of a proxy application, we do
not recommend it. For more information, see Safeguard your
root user credentials and don't use them for everyday tasks in the IAM User Guide.
You can create a mobile-based or browser-based app that can authenticate users using a web identity provider like
Login with Amazon, Facebook, Google, or an OpenID Connect-compatible identity provider. In this case, we
recommend that you use Amazon Cognito or
AssumeRoleWithWebIdentity
. For more information, see Federation Through a Web-based Identity Provider in the IAM User Guide.
Session duration
The temporary credentials are valid for the specified duration, from 900 seconds (15 minutes) up to a maximum of 129,600 seconds (36 hours). The default session duration is 43,200 seconds (12 hours). Temporary credentials obtained by using the root user credentials have a maximum duration of 3,600 seconds (1 hour).
Permissions
You can use the temporary credentials created by GetFederationToken
in any Amazon Web Services
service with the following exceptions:
You cannot call any IAM operations using the CLI or the Amazon Web Services API. This limitation does not apply to console sessions.
You cannot call any STS operations except GetCallerIdentity
.
You can use temporary credentials for single sign-on (SSO) to the console.
You must pass an inline or managed session policy to this operation. You can pass a single JSON policy document to use as an inline session policy. You can also specify up to 10 managed policy Amazon Resource Names (ARNs) to use as managed session policies. The plaintext that you use for both inline and managed session policies can't exceed 2,048 characters.
Though the session policy parameters are optional, if you do not pass a policy, then the resulting federated user
session has no permissions. When you pass session policies, the session permissions are the intersection of the
IAM user policies and the session policies that you pass. This gives you a way to further restrict the
permissions for a federated user. You cannot use session policies to grant more permissions than those that are
defined in the permissions policy of the IAM user. For more information, see Session
Policies in the IAM User Guide. For information about using GetFederationToken
to create
temporary security credentials, see GetFederationToken—Federation Through a Custom Identity Broker.
You can use the credentials to access a resource that has a resource-based policy. If that policy specifically
references the federated user session in the Principal
element of the policy, the session has the
permissions allowed by the policy. These permissions are granted in addition to the permissions granted by the
session policies.
Tags
(Optional) You can pass tag key-value pairs to your session. These are called session tags. For more information about session tags, see Passing Session Tags in STS in the IAM User Guide.
You can create a mobile-based or browser-based app that can authenticate users using a web identity provider like
Login with Amazon, Facebook, Google, or an OpenID Connect-compatible identity provider. In this case, we
recommend that you use Amazon Cognito or

. For more information, see Federation Through a Web-based Identity Provider in the IAM User Guide.
An administrator must grant you the permissions necessary to pass session tags. The administrator can also create granular permissions to allow you to pass only specific session tags. For more information, see Tutorial: Using Tags for Attribute-Based Access Control in the IAM User Guide.
Tag key–value pairs are not case sensitive, but case is preserved. This means that you cannot have separate
Department
and department
tag keys. Assume that the user that you are federating has
the Department
=Marketing
tag and you pass the department
=
engineering
session tag. Department
and department
are not saved as
separate tags, and the session tag passed in the request takes precedence over the user tag.

Returns a set of temporary credentials for an Amazon Web Services account or IAM user. The credentials consist of
an access key ID, a secret access key, and a security token. Typically, you use GetSessionToken
if
you want to use MFA to protect programmatic calls to specific Amazon Web Services API operations like Amazon EC2
StopInstances
.
MFA-enabled IAM users must call GetSessionToken
and submit an MFA code that is associated with their
MFA device. Using the temporary security credentials that the call returns, IAM users can then make programmatic
calls to API operations that require MFA authentication. An incorrect MFA code causes the API to return an access
denied error. For a comparison of GetSessionToken
with the other API operations that produce
temporary credentials, see Requesting Temporary
Security Credentials and Comparing the Amazon Web Services STS API operations in the IAM User Guide.
