[ aws . iam ]



Lists the virtual MFA devices defined in the AWS account by assignment status. If you do not specify an assignment status, the action returns a list of all virtual MFA devices. Assignment status can be Assigned , Unassigned , or Any .

You can paginate the results using the MaxItems and Marker parameters.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

list-virtual-mfa-devices is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: VirtualMFADevices


[--assignment-status <value>]
[--max-items <value>]
[--cli-input-json <value>]
[--starting-token <value>]
[--page-size <value>]
[--generate-cli-skeleton <value>]


--assignment-status (string)

The status (Unassigned or Assigned ) of the devices to list. If you do not specify an AssignmentStatus , the action defaults to Any which lists both assigned and unassigned virtual MFA devices.

Possible values:

  • Assigned
  • Unassigned
  • Any

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.


To list virtual MFA devices

The following list-virtual-mfa-devices command lists the virtual MFA devices that have been configured for the current account:

aws iam list-virtual-mfa-devices


  "VirtualMFADevices": [
      "SerialNumber": "arn:aws:iam::123456789012:mfa/ExampleMFADevice"
      "SerialNumber": "arn:aws:iam::123456789012:mfa/Fred"

For more information, see Using a Virtual MFA Device with AWS in the Using IAM guide.


VirtualMFADevices -> (list)

The list of virtual MFA devices in the current account that match the AssignmentStatus value that was passed in the request.


Contains information about a virtual MFA device.

SerialNumber -> (string)

The serial number associated with VirtualMFADevice .

Base32StringSeed -> (blob)

The Base32 seed defined as specified in RFC3548 . The Base32StringSeed is Base64-encoded.

QRCodePNG -> (blob)

A QR code PNG image that encodes otpauth://totp/$virtualMFADeviceName@$AccountName?secret=$Base32String where $virtualMFADeviceName is one of the create call arguments, AccountName is the user name if set (otherwise, the account ID otherwise), and Base32String is the seed in Base32 format. The Base32String value is Base64-encoded.

User -> (structure)

The IAM user associated with this virtual MFA device.

Path -> (string)

The path to the user. For more information about paths, see IAM Identifiers in the Using IAM guide.

UserName -> (string)

The friendly name identifying the user.

UserId -> (string)

The stable and unique string identifying the user. For more information about IDs, see IAM Identifiers in the Using IAM guide.

Arn -> (string)

The Amazon Resource Name (ARN) that identifies the user. For more information about ARNs and how to use ARNs in policies, see IAM Identifiers in the Using IAM guide.

CreateDate -> (timestamp)

The date and time, in ISO 8601 date-time format , when the user was created.

PasswordLastUsed -> (timestamp)

The date and time, in ISO 8601 date-time format , when the user's password was last used to sign in to an AWS website. For a list of AWS websites that capture a user's last sign-in time, see the Credential Reports topic in the Using IAM guide. If a password is used more than once in a five-minute span, only the first use is returned in this field. If the field is null (no value) then it indicates that they never signed in with a password. This can be because:

  • The user never had a password.
  • A password exists but has not been used since IAM started tracking this information on October 20th, 2014.

A null does not mean that the user never had a password. Also, if the user does not currently have a password, but had one in the past, then this field contains the date and time the most recent password was used.

This value is returned only in the get-user and list-users actions.

EnableDate -> (timestamp)

The date and time on which the virtual MFA device was enabled.

IsTruncated -> (boolean)

A flag that indicates whether there are more items to return. If your results were truncated, you can make a subsequent pagination request using the Marker request parameter to retrieve more items. Note that IAM might return fewer than the MaxItems number of results even when there are more results available. We recommend that you check IsTruncated after every call to ensure that you receive all of your results.

Marker -> (string)

When IsTruncated is true , this element is present and contains the value to use for the Marker parameter in a subsequent pagination request.
