Authlib
=======

Discussion
----------

Authlib implementation for Flask. Flask-oidc uses ouath2client to create a flow based on
client secrets using this function `client.flow_from_clientsecrets
<https://oauth2client.readthedocs.io/en/latest/source/oauth2client.client.html#oauth2client.client.flow_from_clientsecrets>`_.
to create an ouath2 webserver flow which validates based on oidc tokens. This needs to
be replaced using a new library.

Authlib has the functionality to follow this flow and use oidc on top of oauth2
functionality
https://docs.authlib.org/en/latest/client/oauth2.html#oauth-2-openid-connect

Conclusion
----------

Authlib provides the necessary tooling to do this replacement which shows it as suitable
for a replacement
