Using Microsoft Authenticator on smart watches If you lose or change the device you use for MFA you will need a second authentication method in order to set up a new device. We recommend that you explore the other available authentication methods and choose one that suits you best. If you do not yet have a second MFA method set up this is a great time to do so. This will not affect your second method of authentication, if you have this set up, which you will be able to use as usual. If you do not have the option to input the numbers into your Microsoft Authenticator app when requested, it may be that you need to upgrade your Authenticator app to the latest version. This will confirm that it is you making the request and will complete the MFA approval process in Authenticator. The number shown on your SSO login (illustrated above) should then be entered into the notification on your app and confirmed by pressing ‘Yes’. Enter the number from your SSO login into the app and click on 'yes'
