Microsoft Authenticator

Our take

This is the kind of app you install once and forget about, which is a compliment for a security tool. Nothing flashy, no engagement tricks, just a straightforward second factor that works the way it’s supposed to.

About Microsoft Authenticator

Use Microsoft Authenticator for easy, secure sign-ins for all your online accounts using multi-factor authentication or passwordless. You also have additional account management options for your Microsoft personal, work or school accounts.

Getting started with multi-factor authentication

Multi factor authentication (MFA) or two factor authentication (2FA) provides a second layer of security. When logging in with multi-factor authentication, you’ll enter your password, and then you’ll be asked for an additional way to prove it’s really you. Either approve the notification sent to the Microsoft Authenticator, or enter the one-time password (OTP) generated by the app. The one-time passwords (OTP codes) have a 30 second timer counting down. This timer is so you never have to use the same time-based one-time password (TOTP) twice and you don’t have to remember the number. The one-time password (OTP) doesn’t require you to be connected to a network, and it won’t drain your battery. You can add multiple accounts to your app, including non-Microsoft accounts like Facebook, Amazon, Dropbox, Google, LinkedIn, GitHub, and more.

Getting started with passwordless

Use your phone, not your password, to log into your Microsoft account. Just enter your username, then approve the notification sent to your phone. Your fingerprint, face ID, or PIN will provide a second layer of security in this two-step verification process. After you’ve signed in with two factor authentication (2FA), you’ll have access to all your Microsoft products and services, such as Outlook, OneDrive, Office, and more.

Microsoft personal, work or school accounts

Sometimes your work or school might ask you to install the Microsoft Authenticator when accessing certain files, emails, or apps. You will need to register your device to your organization through the app and add your work or school account. Microsoft Authenticator also supports cert-based authentication by issuing a certificate on your device. This
