Q. Is it possible to register multiple other people's accounts in a single multi-factor authentication app (such as Microsoft Authenticator)? I would like to set it up on a shared computer using an authentication app like WinAuth, in case someone forgets their smartphone.
A. Multi-Factor Authentication is a system that verifies a user's identity using possession or biometric information that belongs to the actual user.
Authentication apps cannot be set up on devices that are not owned by the user.
Authentication apps designed for use on PCs, such as WinAuth for Windows, are not supported for THERS account authentication.
