What is Cognito user groups?
With Groups support in Cognito, developers can easily customize users’ app experience by creating groups which represent different user types and app usage permissions. Developers have the ability to add users and remove users from groups and manage group permissions for sets of users.
Can you assign an AWS role to a user?

What is Cognito?
Amazon Cognito is an Amazon Web Services product that controls user authentication and access for mobile applications on internet-connected devices. Amazon Cognito collects a user’s profile attributes into directories called user pools that a mobile app or web app uses to configure limited access to AWS resources.
What is the main difference between Cognito user pool and Cognito identity pool?
With a user pool, your app users can sign in through the user pool or federate through a third-party identity provider (IdP). Identity pools are for authorization (access control). You can use identity pools to create unique identities for users and give them access to other AWS services.
How do you assign a user to a role?
Assign roles in user profile
- Go to Dashboard > User Management > Users and click the name of the user.
- Click the Roles view, and click Assign Role.
- Choose the role you wish to assign and click Assign.
Why do we use Cognito?
Amazon Cognito lets you easily add user sign-up and authentication to your mobile and web apps. Amazon Cognito also enables you to authenticate users through an external identity provider and provides temporary security credentials to access your app’s backend resources in AWS or any service behind Amazon API Gateway.
How does the Cognito identity work in AWS?
Cognito Identity assigns users a set of temporary, limited privilege credentials to access the AWS resources from your application without having to use AWS account credentials. The permissions for each user are controlled through AWS IAM roles that you create.
Can a user be in multiple groups in Amazon Cognito?
When group members sign in using Amazon Cognito, they can receive temporary credentials from the identity pools. Their permissions are determined by the associated IAM role. Individual users can be in multiple groups. As a developer, you have the following options for automatically choosing the IAM role when a user is in multiple groups:
Can a user assume a role in AWS?
AWS Role has policies attached to it but not associated with one person. A role can be assumed by any user who needs it but cannot be assigned to Users or Groups. Amazon Cognito identity pools provide temporary AWS credentials for users who are guests.
How does access control work in Amazon Cognito?
Amazon Cognito identity pools assign your authenticated users a set of temporary, limited privilege credentials to access your AWS resources. The permissions for each user are controlled through IAM roles that you create. You can define rules to choose the role for each user based on claims in the user’s ID token.
