Migrate or Reset the Microsoft Authenticator App (New Phone / Lost Access)

Use this procedure when you get a new phone, are locked out of Microsoft Authenticator, or need to reset your MFA credentials.

Before you start: can you still sign in to office.com on another device?

• Yes — follow the steps below. You can do this yourself.
• No — you're locked out, and MFA has to be reset by IT. Tell the MCi IT Assistant and it will raise a ticket for you.

Steps to migrate or reset the Authenticator app:

1. Go to https://www.office.com/?auth=2 and click on your profile, then select "View account."
2. Navigate to the "Security info" tab and delete the old authentication method.
3. Click "Add sign-in method" and select "Authenticator app." A QR code appears on your PC.
4. On your new phone, install the Microsoft Authenticator app, open it, and select "Add work or school account."
5. Scan the QR code shown on your PC with the new phone, then click "Next" to finish.

Note: MCi does not administer Concur, so Concur MFA is set up inside Concur itself — log in to Concur, install an authenticator app of your choice, scan the QR code on the Concur sign-in page, and enter the resulting 6-digit code.
