New phone? Move your authenticator before you wipe the old one

Microsoft Authenticator on your phone is what approves your work sign-ins. If you wipe or trade in your old phone before moving it, you can lock yourself out of email, Teams and everything else.

Before you switch

1. Keep your old phone working until the new one is set up. Don't reset or trade it in yet.
2. Install Microsoft Authenticator on the new phone.
3. On your computer, go to mysignins.microsoft.com/security-info and sign in. Select Add sign-in method, choose Microsoft Authenticator, and scan the QR code with your new phone.
4. Test it by signing out and back in, approving on the new phone.
5. Then remove the old phone from the list on the same page.

Repeat for any other work apps that use a code from your phone.
