Setup Microsoft Authenticator App Authentication

When it comes to Two-Factor Authentication methods, using an authenticator app to generate your Two-Factor login codes is far more secure than text message. The reason? It’s more difficult for a hacker to gain physical access to your phone and generate a code without you knowing about it.

Alex Weinert, Microsoft’s Director of Identity Security, recently wrote “I want to do what I can to convince you that it’s time to start your move away from SMS and voice Multi-Factor Authentication (MFA) mechanisms.” SMS messages are open to compromise in a way that other forms of MFA are not.

There are plenty of authenticator apps available for free (Authy, Evernote, or Google Authenticator to name a few) and all offer similar functionality. If you frequently use Microsoft applications and services, the Microsoft Authenticator is a handy tool. Microsoft Authenticator supports password-less logins for all Microsoft apps.
