Dear Maryna Gal
Good day!
Thank you for posting to Microsoft Community. We are glad to assist!
Based on your description, I understand you concern with unable to log into your Microsoft account due to Authenticator app.
I sincerely suggest you to post to the Microsoft Authenticator app in the Microsoft Authenticator app forum, because your query relates to Authenticator app. Microsoft has a support channel resource specific to certain different support scopes and attributes, that team has special expertise in queries related to the Authenticator app, so they can check and provide you with more details.
Thanks for your precious time and your understanding would be highly appreciated. Have a nice day!
Best regards,
