What is 2FA?
Two-Factor Authentication (2FA) works by adding an additional layer of security to your online accounts. It requires an additional login 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, increasing security and reducing fraud risks.
Using 2FA with the Merchant Management System (MMS)
The MMS requires users to authenticate their account using a third-party authentication app to obtain a secure verification code.
By default, the MMS recommends that the user downloads the Google Authenticator app, details of which can be found on Google's website. However, the Gateway is configured to work with most third-party authentication apps.
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 the MMS.
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.
