REST APIs with Flask and Python - Logging Out Users in Your Rest API

This video tutorial explains how to implement a user logout feature using JWT and a blacklist. It covers initializing a blacklist as an empty set, adding a user logout resource, and creating a POST request to blacklist the JWT ID. The tutorial emphasizes the importance of blacklisting the JWT ID instead of the user ID to allow users to log back in.
