# MFA / OTP - Multi Factor Authentication

PSI multi factor authentication is based on a Microsoft Authenticatior infrastructure.

This is how you can configure our account so that you are able to use any OTP instead of Microsoft Authenticator.

If you want to set OTP based authentication as default change the Standard Authentication Method to "Authenticator-App or Hardwaretoken - Code"

After changing the default authentication method to "Authenticator-App or Hardwaretoken - Code" you should always get a second prompt for the OTP value instead of the Microsoft Authenticatior push message.
