Token Auth Example won't run with with itsdangerous > 2.0

[pmaresca]

Hey there, was just trying to run the token_auth.py example and it doesn't seem like the imports succeed with the latest version of itsdangerous. I seem to have 2.1.2 installed in my venv and it looks like they deprecated the serializer utilized in 2. https://itsdangerous.palletsprojects.com/en/2.0.x/jws/#itsdangerous.jws.JSONWebSignatureSerializer
Just thought you'd wanna know for future people trying to run your example.

Thanks, yes, I should update that example to use pyjwt.
