Answer 2

Answer:

Token-based authentication is a protocol which allows users to verify their identity, and in return receive a unique access token. Tokens offer a second layer of security, and administrators have detailed control over each action and transaction. But using tokens requires a bit of coding know-how.

When the access token expires, the application will be forced to make the user sign in again, so that you as the service know the user is continually involved in re-authorizing the application.
