Reset existing multi-factor authentication configuration for a user

Your user may lose access to the device that they used to register with multi-factor authentication. When this occurs, you need to reset their multi-factor settings so that they can re-register.

Use the following steps to reset the existing multi-factor authentication configuration for a user:

1. Log in to your Office 365 Control Panel.
2. From the left menu, select Office 365 Admin Center.
3. From the top menu, select Multi-factor authentication.
4. Select the check box next to the user you need to enforce multi-factor authentication for.
5. Under quick steps, select Manage user settings.
6. Select the check box next to Require selected users to provide contact methods again.
7. Select save then close.
8. The selected user can now log in to their Office 365 account and re-register with multi-factor authentication.
