1 - About

The sign-in state

After users have a confirmed account, they will be able to sign in:

  • They gives their username (or email) and password.
  • On internet,:
    • a JavaScript function then communicates with Amazon Cognito, authenticates using the Secure Remote Password protocol (SRP), and receives back a set of JSON Web Tokens (JWT).
    • The JWTs contain claims about the identity of the user
    • The JWT is used to authenticate against the RESTful API (build with Amazon API Gateway)
