1- What is 2-factor authentication (general information)?
2-Factor Authentication (2FA) is an electronic authentication method where users can only access the application after providing two answers (factors) to prove their identity. It is mainly used to ensure that user data is protected and secured. A third-party authentication app enables two-factor authentication, usually by displaying a randomly generated and frequently changing code to be used for authentication.
By default, FLOW portal supports setting up 2FA using the Google Authenticator app (or using SMS if enabled by the project). The setup and use of the 2FA can be optional or mandatory, depending on the project the users are logging into.

3- I try to log in, but a pop-up message appears asking me to enter the PIN code. Where can I find that code?
If you set up your 2FA with the Google Authenticator app, you can find that code in the Google Authenticator app in your phone. The pin code is shown there and is changed every minute. Note: In case you have used the Google Authenticator app to set up more than one site, the correct PIN code will be shown under the related FLOW site name.
If you set up your 2FA via SMS, an SMS message with the PIN code will be sent to your phone.
4- I entered a wrong PIN code in the notification popup on the login page, I get another popup saying "The PIN code is invalid". Then what can I do?
You can close the popup and refresh the page. Then try to log in again with a correct valid PIN code.
5- Something went wrong with the Authenticator app where I can no longer find the PIN codes. Or I accidentally deleted the related site and no longer have the PINs to log in. How do I regain access to my account?
Reset your password by clicking the "Forgot Password" link in the login screen. Follow the password reset steps and then set up your 2FA again.
