We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Replace flask_oauthlib with Authlib

**Description**

flask_oauthlib has been deprecated in favour of Authlib. It would be good if airflow starts using Authlib

**Use case / motivation**

FlaskAppBuilder is now using Authlib. 
Since FlaskAppBuilder is deeply integrated into Airflow, it will be good to also have this Authlib. Flask-oauthlib documentation recommends Authlib
