How can I add a logout feature to secure-token? Do I need a database or is there a better way?

Hi 👋
I'm developing a package called secure-token, designed for managing secure tokens.
I’d like to add a feature that allows a user to log out (that is, invalidate their current token).

My questions are:

1. Do I need to connect to a database to store valid/invalid tokens for this?
2. Is there any way to implement logout without a database — for example, using encryption or TTL-based tokens?
3. If I want this feature to work across different frameworks (Django, Flask, FastAPI, etc.),
   should I build it directly inside this package or create separate framework-specific packages that depend on this one?

I'd really appreciate any ideas or experiences from others 🙏
