How do I implement logout functionality in a Flask app using JWT?

To implement logout in a Flask app using JWT, you can simply invalidate the token on the client side. Since JWTs are stateless, you can't directly revoke them on the server.

What if I want to make the token invalid 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 each request.

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.

Can you show me a code example for that?

Sure! Here's a simple example using Flask and Redis to manage a token blacklist.
