Microsoft Authenticator

The Microsoft Authenticator app helps you sign in to your accounts when you're using two-step verification. Two-step verification helps you to use your accounts more securely because passwords can be forgotten, stolen, or compromised.

The Microsoft Authenticator app backs up your account credentials and related app settings, such as the order of your accounts, to the cloud. Important: You need a personal Microsoft account to act as your recovery account. iOS users must also have an iCloud account.

If you don't want to use email, a phone call, or text, you can use the Microsoft Authenticator app to help strengthen your account security and to sign-in without passwords.
