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