Microsoft Authenticator provides multi-factor authentication options, as well as a password manager. Here's what you should know about the app.

I prefer the option to use an authenticator app rather than receiving codes via text message whenever possible, and so should you. The reason is simple logistics.

Secure your Microsoft account to protect your email, purchases and billing information. Enable two-step verification via Authenticator App.

If your Microsoft Authenticator app is not working or displaying code for the accounts, then follow the suggestions to fix the issue using multiple methods.

If the Microsoft Authenticator app doesn’t cover all your needs, support for FIDO2 hardware security devices is also coming. That could be a Yubikey, or even a fitness tracker like the Motiv Ring.

In order to use Autofill within the Microsoft Authenticator app, you need to be running iOS 12 or above or Android 6 or above on your phone.

If you’ve already been storing passwords through another app, the first task on your to-do list is to import those passwords into Microsoft Authenticator.

Microsoft is unifying its various authenticator apps into a single Microsoft Authenticator one that will begin rolling out to consumers and business users as of August 15.
