Authenticate email accessed through laptop using new phone

Chandy George Kanianthara (Prof) 0 Reputation points

I recently replaced my iPhone7 with an iPhone15. The Microsoft Authenticator on the new phone is unable to provide 2-factor authentication to my email account accessed through my laptop computer. With my earlier phone this happened automatically and all I had to click was approve. How do I reconnect the Authenticator on the new phone to my laptop account? The Authenticator does say that the new device is registered with my university.

    @Chandy George Kanianthara (Prof), Thanks for posting in Q&A. Based on my researching, to be secure, Microsoft Authenticator MFA is with Number matching experience.

    Relevant services will begin deploying these changes after May 8, 2023 and users will start to see number match in approval requests. As services deploy, some may see number match while others don't.

    If you see the Number matching in Microsoft Authenticator app. This is the default behavior considering of security reason.

    Hope the above information can help.

    You can restore from an authenticator cloud backup (assuming there was one) but make sure no accounts have been added to the newly install app. Then sign on with recovery account to do the restore.

    You can recover your account credentials from your cloud account, but you must first make sure that the account you're recovering doesn't exist in the Microsoft Authenticator app. For example, if you're recovering your personal Microsoft account, you must make sure you don't have a personal Microsoft account already set up in the authenticator app. This check is important so we can be sure we're not overwriting or erasing an existing account by mistake.
