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. Your fingerprint, face ID, or PIN will provide a second layer of security in this two-step verification process. Just enter your username, then approve the notification sent to your phone. Use your phone, not your password, to log into your Microsoft account. You can add multiple accounts to your app, including non-Microsoft accounts like Facebook, Amazon, Dropbox, Google, LinkedIn, GitHub, and more. The one-time password (OTP) doesn’t require you to be connected to a network, and it won’t drain your battery. 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. 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. 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. Multi factor authentication (MFA) or two factor authentication (2FA) provides a second layer of security.

Getting started with multi-factor authentication

You also have additional account management options for your Microsoft personal, work or school accounts. Use Microsoft Authenticator for easy, secure sign-ins for all your online accounts using multi-factor authentication, passwordless, or password autofill. Install Microsoft Authenticator on your Android device and make your study or work more efficient! Greater protection will be given when the second layer of security is toggled on.

Instead, face ID, fingerprint and PIN code are introduced here. There's no need for users to input a long password. Microsoft Authenticator, a Microsoft account security app, promises its users an easier and faster way to sign in.
