Microsoft Authenticator

Microsoft Authenticator offers a simple and secure way to sign in to all your online accounts using multi-factor authentication, passwordless, or password autofill. In addition, you can manage your Microsoft personal, work, or school accounts.

To get started with multi-factor authentication, you will need to enter your password and then provide additional proof of your identity, such as approving a notification sent to the Microsoft Authenticator app or entering a one-time password generated by the app, which has a 30-second countdown timer to prevent reuse. You can add multiple accounts to the app, including non-Microsoft accounts like Facebook, Amazon, Dropbox, and LinkedIn.

With passwordless sign-in, you can use your phone to log in by entering your username and then approving the notification sent to your phone, which can be verified using your fingerprint, face ID, or PIN.

Furthermore, the Microsoft Authenticator app can autofill your passwords for you on the Passwords tab, syncing with your personal Microsoft account and other password managers, such as Google Chrome. Your passwords are protected with multi-factor authentication, which requires proof of your identity before you can access and autofill them on your mobile device.

If you have Microsoft personal, work, or school accounts, you may be required to install the Microsoft Authenticator app to access certain files, emails, or apps. You can register your device with the app and add your work or school account to support cert-based authentication, which lets your organization know the sign-in request is coming from a trusted device. With single sign-on supported, once you have proven your identity once, you can easily and securely access other Microsoft apps and services on your device without the need to log in again.
