Best way to retrieve user data from a cognito access token

Question

Hi, I am curious to know about the cognito endpoint quota and the best practices when designing a robust login authentication system. Is it wise to call the getuser() method with access token to get the user data like username or is there any other better way? Looking forward to an answer.

Answer

Hi

I think the information you need is included in either the ID or Access token, both should be returned when the user login. You could fetch the information by decoding the JWT based tokens.

See: [Using the ID token](https://docs.aws.amazon.com/cognito/latest/developerguide/amazon-cognito-user-pools-using-the-id-token.html) and [Using tokens with user pools](https://docs.aws.amazon.com/cognito/latest/developerguide/amazon-cognito-user-pools-using-tokens-with-identity-providers.html)
