Amazon Cognito

Along with this, Amazon Cognito also provides us the ability to provide temporary AWS credentials to the users. For each of these functionalities, it has a pool.

How Amazon Cognito works

In Amazon Cognito, we can create two types of pools: user and identity pools.

• User pools: We can create our user directory to store user profiles. We can also use user pools to add third-party identity providers such as Facebook, Google, Amazon, Apple, SAML, and OIDC. Cognito provides us with a user interface for our sign-up and sign-in page. These pages can be customized according to our application’s requirements.

• Identity pools: We can give users access to various AWS services and AWS APIs by generating temporary credentials. We can also create specific roles to allow limited access to these services for both AWS and external users.
