AWS managed policies for Amazon Cognito
To add permissions to users, groups, and roles, it is easier to use AWS managed policies than to write policies yourself. It takes time and expertise to create IAM customer managed policies that provide your team with only the permissions they need. To get started quickly, you can use our AWS managed policies. These policies cover common use cases and are available in your AWS account. For more information about AWS managed policies, see AWS managed policies in the IAM User Guide.
AWS services maintain and update AWS managed policies. You can't change the permissions in AWS managed policies. Services occasionally add additional permissions to an AWS managed policy to support new features. This type of update affects all identities (users, groups, and roles) where the policy is attached. Services are most likely to update an AWS managed policy when a new feature is launched or when new operations become available. Services do not remove permissions from an AWS managed policy, so policy updates won't break your existing permissions.
Additionally, AWS supports managed policies for job functions that span multiple services. For example, the ReadOnlyAccess AWS managed policy provides read-only access to all AWS services and resources. When a service launches a new feature, AWS adds read-only permissions for new operations and resources. For a list and descriptions of job function policies, see AWS managed policies for job functions in the IAM User Guide.
A number of policies are available via the IAM Console that you can use to grant access to Amazon Cognito:
-
AmazonCognitoPowerUser- Permissions for accessing and managing all aspects of your identity pools and user pools. To view the permissions for this policy, see AmazonCognitoPowerUser. -
AmazonCognitoReadOnly- Permissions for read-only access to your identity pools and user pools. To view the permissions for this policy, see AmazonCognitoReadOnly. -
AmazonCognitoDeveloperAuthenticatedIdentities- Permissions for your authentication system to integrate with Amazon Cognito. To view the permissions for this policy, see AmazonCognitoDeveloperAuthenticatedIdentities.
These policies are maintained by the Amazon Cognito team, so even as new APIs are added, your users continue to have the same level of access.
Note
When you create a new identity pool, you can automatically create new roles for authenticated and guest user access. The administrator who creates your identity pool with new IAM roles must also have IAM permissions to create roles.
Identity pools with unauthenticated guest access apply an additional AWS managed policy,
AmazonCognitoUnAuthedIdentitiesSessionPolicy, as a session policy to
unauthenticated users. This AWS managed policy has no intended administrative use. Instead,
it limits the scope of permissions that you can apply to guest users in the identity pools
enhanced authentication flow. For more information, see IAM roles.
