Dear Luci Ridolfo
Good day!
Thank you for posting to Microsoft Community. We are glad to assist!
I do apologize for any inconvenience this may have caused you, after doing some research I found a similar thread to your, you may refer to the solution shared in microsoft authenticator app gives 8 digit code instead of required 6 for azure
If that doesn’t help resolve your issue, it is suggested to post to the Microsoft Authenticator app in the Microsoft Authenticator app forum, because your query relates to device switching. 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,
