What is 2FA?
Two-Factor Authentication (2FA) works by adding an additional layer of security to your online accounts. It requires an additional log in credential – beyond just the username and password – to gain account access, and getting that second credential requires access to something that belongs to you.
When using the MMS the second factor is a one-time passcode generated by an authenticator app:
What are the benefits of using 2FA?
Two-factor authentication works as an extra step in the process, a second security layer, that will re-confirm your identity. Its purpose is to reduce the likelihood of someone other than you accessing your account so this increases security and reduces fraud risks.
Using 2FA with the Merchant Management System (MMS)
Logging in using 2FA is required to change specific settings within the MMS. The Google Authenticator Guide goes through the steps required to set up the Google Authenticator app on your mobile device (there is also an option to receive codes on your pc via a browser extension). This app allows you to use two-factor authentication (2FA) with MMS.
Once configured, you can use the Google Authenticator app to receive codes. You can set up Google Authenticator or another app that creates one-time verification codes when you do not have an internet connection or mobile service. Once you have received the code, enter it on the sign-in screen to confirm it is you.
Alternatively, you can consider using other applications like Authy, LastPass Authenticator etc. NB: this is a one-time registration process, and only one 2FA authenticator can be used per user account.
