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)
