Product: Microsoft Authenticator
Device & OS: not provided
Scenario: Setting up authentication apps after upgrading or replacing a mobile device.

Before you start

Ensure your new phone has a stable internet connection and that you still have access to your old phone or recovery codes before attempting to troubleshoot.

Solution 1Recommended

Restore Authenticator Accounts from Cloud Backup

Use this method to quickly recover your accounts on the new device if you previously enabled cloud backup on your old phone.

Microsoft Authenticator allows you to back up account credentials to a personal Microsoft account. This is the fastest way to migrate to a new device without manually re-registering each account.

Open the App

Install and open the Microsoft Authenticator app on your new phone. Do not add any new accounts manually yet.

Initiate Recovery

Tap 'Begin recovery' at the bottom of the welcome screen.

Sign In to Recovery Account

Verify Restored Accounts

Once the restore completes, check your accounts. Some enterprise or school accounts may ask for additional verification to become fully active.

Solution 2

Enable Notification Permissions

Solution 3

Contact Your Organization's IT Administrator

Necessary if you are completely locked out of a work or school account and did not set up a backup or alternative sign-in method.

Frequently Asked Questions

Why didn't my Microsoft Authenticator accounts transfer to my new phone automatically?

For security purposes, authentication tokens are uniquely tied to the physical hardware of your device. They do not automatically transfer to a new phone unless you use the encrypted cloud backup feature and verify your identity during the migration.

What should I do if I wiped my old phone before setting up Authenticator on the new one?

If you did not create a backup and no longer have access to the old device, you must use an alternative sign-in method (such as an SMS code or backup codes) or contact your IT administrator to reset your account's MFA settings.

Can I use Microsoft Authenticator on two phones at the same time?

Yes, but you must manually set up or restore the accounts on both devices. Note that some enterprise organizations intentionally restrict MFA to a single registered device for security compliance.

How do I turn on cloud backup for Microsoft Authenticator?

On your device, open the Authenticator app, navigate to Settings, and toggle on 'Cloud backup' (iOS) or 'Cloud backup' (Android). You will need to link a personal Microsoft account to securely store the backup data.
