Microsoft Authenticator works by generating OTP (one-time-password) codes that must be entered in the appropriate fields to access an account. It is not difficult to understand how to access Microsoft Authenticator, as it can be done both if you have an account and if you do not have one.

In case you already have a Microsoft account, the steps are as follows:

  • Download Microsoft Authenticator app via Google Play Store and App Store.
  • Enter your credentials.
  • Select to receive an SMS code or via e-mail to confirm access.
  • After entering the code, you will be then logged into Microsoft Authenticator.
  • Remember that, in case you are logged in this way, that is with the Microsoft account, you can access their services without necessarily having to type the password. Just enter the 2FA code of the app.

Now, let’s move on to the quick setup for those who don’t have a Microsoft account. This happens if you need to enable 2FA on a non-Microsoft account via Microsoft Authenticator:

  • Download and prepare the app, by going to the add account section and then to another account.
  • Open the page of the site on which you need to activate the authentication service. A QR code and a string of numbers and letters will appear below.
  • You can simply scan the QR and follow the steps from the Microsoft app to activate authentication.
  • If you don’t want to scan, you can go to “enter code manually” in the app, and type the code shown below the QR code.
  • Once one of the two codes has been scanned or entered, you can give the code shown a name (e.g. bank account), and a new code will be generated every 30 seconds to increase the security level.
