I lost my device or moved on to a new device. How do I make sure notifications do not continue to go to my old device?

If you are using a new device to multi-factor authentication (MFA), there are two ways you can remove your previous device from the authentication app:

• From a personal Microsoft account, go to the two-step verification area of your Account Security page and turn off verification for your old device.
• From a work or school Microsoft account go to the two-step verification area of your MyApps page or to your organisation’s custom portal and turn off verification for your old device.
