How can I implement logout functionality using Flask and JWT?

To implement logout with Flask and JWT, you can simply invalidate the JWT token on the client side. This means removing it from local storage or cookies.

What if I want to invalidate the token on the server side?

You can maintain a blacklist of tokens on the server. When a user logs out, add their token to this blacklist and check against it for future requests.

How do I create a blacklist for tokens?

You can use a database or an in-memory store like Redis to keep track of blacklisted tokens along with their expiration times.

Is there a way to automatically expire tokens?

Yes, you can set an expiration time when creating the JWT. After this time, the token will no longer be valid.
