Moving Microsoft Authenticator to a new phone

1. Before you switch, turn on backup in the Authenticator app. On iPhone it saves to iCloud; on Android it's Settings > Cloud Backup.
2. Keep your old phone. Don't wipe it or trade it in yet.
3. Install Microsoft Authenticator on the new phone.
4. On a computer, go to mysignins.microsoft.com/security-info and approve the sign-in on your OLD phone.
5. Click Add sign-in method, choose Microsoft Authenticator, and scan the QR code with the new phone (tap +, then Work or school account).
6. Approve the test notification on the new phone, then sign out of Outlook and Teams and sign back in using only the new phone.
7. Once that works, delete the old phone from the Security info page. Then you can trade it in.
8. Old phone lost or broken and you can't sign in? Contact us; we can issue a temporary pass so you can set up the new phone. Getting approval prompts you didn't start? Tap Deny and call us right away.
