    1. Log in to your Microsoft 365 account (from a computer)

    Go to https://mysignins.microsoft.com/security-info (or you can get there through your Office 365 account → Security info under your profile).


    1. Add a new sign-in method

    Click Add sign-in method → choose Authenticator App.

    Select Next and you’ll see instructions.

    Microsoft will display a QR code on your computer screen.


    1. Scan the QR code with Microsoft Authenticator

    On your new phone, open the Authenticator app.

    Choose Add accountWork or school accountScan QR code.

    Point your phone’s camera at the QR code shown on your computer.


    1. Test and confirm

    Microsoft will usually ask you to approve a test notification in the app.

    • Once you approve it, your Authenticator is re-linked to your account.
