When I installed pyauthenticator and executed it, I got the following message

Traceback (most recent call last):

This error is typically related to an outdated pyauthenticator version, maybe 0.0.7? Try using the more up to date version 0.2.0. The version 0.2.0 requires Python >=3.8 so if you are still using 3.7 this might be a reason why the old pyauthenticator version was installed. Unfortunately, the old version is broken.
