Hi,DanielSmigel
Thanks for visiting Microsoft Community. As well as I understand that you are having issues using the Authenticator.
I wish I could handle your problem, however, as your question relates to developer/development content. it is more suitable for publishing on Microsoft Learn (English only), more users post these issues there, you can click on "Ask a question", there are experts who can provide more professional solutions in that place.
Here are links to the forum where you can raise specific scenarios and share your idea to help solve the problem:
