How to Use Microsoft Authenticator – Microsoft Authenticator is a security application for two-factor authentication. This Android application competes directly with Google Authenticator, Authy, LastPass Authenticator, and several other applications. You can run the application while updating your Microsoft account settings or enable two-factor authentication there. Or you may just want to have TFA (Two-Factor Authentication) available for your own security purposes. This article will discuss how to use Microsoft Authenticator and how it works.

Microsoft Authenticator is a two-factor authentication app from Microsoft. This app was originally launched in beta in June 2016. The way to use the app is the same as most other two-factor authentication apps. You log in to your account and the account asks for a code. This application generates that type of code. This app is very useful for fast sign-in, works across platforms, and is faster than email or text codes.

You can also use the password-free login app for your Microsoft account. This app also comes with multi-account support and support for non-Microsoft websites and services.

How to Use Microsoft Authenticator
Setting up the Microsoft Authenticator app is rather straightforward. Let’s start setting up with your Microsoft account. Simply download the app and open it to start the tutorial.

  1. How to Use Microsoft Authenticator for a Microsoft account

Sign in with your Microsoft account credentials in the Microsoft Authenticator app. This should be your first prompt after opening the application for the first time. Just select Personal account or Work or school account to sign in to your Microsoft account.
After successful login, you must authenticate your login with a code. You can send it via text, email, or another method.
After you enter the code, this app is linked to your Microsoft account and you use it to log in without a password. Next time you log in, just enter your username and then enter the code generated by the app.
These settings vary from website to website, but the general idea of ??using this app remains the same. This is a fairly straightforward process. You can set up the Microsoft Authenticator app for the task by tapping the three-dot menu button in the Microsoft Authenticator app and selecting the Add account option. From there, select the Other account option and be prepared to follow the steps below.

  1. How to Use Microsoft Authenticator for non-Microsoft accounts
    Return to the website where it should ask if you want two-factor authentication via text and email or by app. Select an application option.
    You will either see a QR code on your screen or a six-digit code. Use the Microsoft Authenticator app to scan the QR code.
    Or the site can provide you with a code to enter instead of a QR code. Return to the app and tap the Or Enter Code Manually option at the bottom of the page. Name your account first so you know which one and enter the code under it.
    Microsoft account setup is something you only have to do one at a time. Meanwhile, you can add any online account you want by repeating the non-Microsoft account steps on all your other accounts.

How Microsoft Authenticator Works
Before we discuss how to use Microsoft Authenticator, it would be good if we know how this authentication app works. Microsoft Authenticator works like most other authentication apps. This application generates a series of numbers rotating for about 30 seconds. In other words, the app generates a six-digit code every 30 seconds. You can simply log into your application or service as usual. This site finally asks for a two-factor authentication code. Open the Microsoft Authenticator app to receive these codes.

Microsoft Authenticator works a little differently on Microsoft accounts than on non-Microsoft accounts. You can actually use the code in this app to log in without a password for your Microsoft account. However, with all other account types (Facebook, Google, etc.), you must log in with a username and password before you can add a code.


Microsoft supports any website that uses a TOTP (Time-Based One Time Password) based on the standard. That way, the app can continue to generate code and you can use it as needed. This application differs from the HOTP standard in that a code is generated especially for you once. Sites that use this method, such as Twitter and most likely your banking app, are unable to use Microsoft Authenticator

From the discussion above, how to use Microsoft Authenticator is very easy. You simply sign in with your email or username and password on non-Microsoft websites and enter the six-digit code from the Microsoft Authenticator app when prompted. The Microsoft website only needs you to add your username and then it will ask you for a code from the app. That’s what all these apps do and that’s all they’re designed to do!
