Password-less Authentication for Office 365 and Other Online Services


Password-less authentication uses number matching in the Microsoft Authenticator App to allow MFA-enabled users to log into Office 365 and other online services without entering a password. When going through the authentication process, you will be presented with a number that must be entered in the Authenticator app to complete the authentication. 

The extra step of number matching helps ensure that the person requesting access into an account is the same person approving the sign-in on a device. Without number matching, a bad actor who has obtained someone’s login credentials could attempt to log in, sending a prompt to the victim to approve the sign-in request. If the victim inadvertently approves the request, the bad actor can gain access into the victim’s account.
