About Microsoft Authenticator 6.4.5
TFA (two factor authentication) is easy, convenient, and secure when you use Microsoft Authenticator. Use your phone, not your password, to log into your Microsoft account. You simply have to 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’ll have access to all your Microsoft products and services, such as Outlook, OneDrive, Office, and more.

Microsoft Authenticator also supports multi factor authentication even if you still use a password, by providing a second layer of security after you type your password. When logging in with two 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 OTP code (one time password) generated by the app.
You can add multiple accounts to your app, including non-Microsoft accounts like LinkedIn, Github, Amazon, Dropbox, Google, Facebook, and more. Since the app supports the industry standard for TOTP (time based one time passwords), you can secure all your online accounts. Simply enable two factor authentication on all your accounts. Then, when you sign in, you’ll provide your username and password as usual. Finally, you’ll enter the OTP code (one time password) provided by the Microsoft Authenticator app.
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 will let your organization know that the sign-in request is coming from a trusted device and help you seamlessly and securely access additional Microsoft apps and services without needing to log into each. Because Microsoft Authenticator supports single sign-on, once you have proven your identity once, you will not need to log in again to other Microsoft apps on your device.
