Microsoft authenticator not working

Question

I have just gotten a new phone and signed into my Microsoft authenticator account on the app. However, no notification codes are being sent to my microsoft authenticator app on my phone, so I cannot sign in to any of my accounts on any of my devices. Any help with this would be greatly appreciated, thanks.

Hello Niamh Langley,

You need to backup your data.

To transfer your data from one phone to another you need to backup the existing phone's MFA data.

To move your authenticator app and configure accounts without losing data, you need to:

• Go to your authenticator app
• Open Microsoft Authenticator. Tap the three vertical dots at the top right, and then tap "Settings."
• In the "Backup" section, toggle-On "Cloud Backup" on an Android phone, or "iCloud Backup" on an iPhone.
• This will proceed to back up your data. (Note, this will back this up to the account you used to set authenticator up)

You can then proceed to navigate to your new phone

• Open your fresh Authenticator and navigate to recovery tool. In recovery you should see >> "Already have a back up? sign in to your recovery account"
• Once you do this, You'll be asked to sign in to the Microsoft account you used for the backup on your old phone. Your accounts will then automatically be added to Microsoft Authenticator on your new one.

Pls note that some accounts will ask you to revalidate, to confirm it is you. by signing in to those accounts or scanning a QR code. Microsoft Authenticator will display a message if you need to do this.

Once done test all your accounts are present then go ahead and remove from your old phone

Hi @Niamh Langley

Thank you for posting this in Microsoft Q&A.

Adding to the above information provided by @akinbade abiola

If you cannot transfer your data from your old phone, you will need to re-register for Multi-Factor Authentication (MFA) on your new device. Please contact your global administrator to request the necessary re-registration of MFA for your account. This process will remove all current authentication methods associated with your account and prompt you to set up MFA during the sign-in process.
