Hi @jwcomley,
Thanks for reaching out! Wordfence two-factor authentication uses an authenticator application, such as Google Authenticator, to generate unique codes for you.
To use 2FA, first, you’ll need to choose an authenticator application to use, if you do not already have one installed on a cell phone or tablet. There are many available for iOS, Android, and other platforms.
You can find a list of common authenticator applications as well as our 2FA setup documentation here: https://www.wordfence.com/help/tools/two-factor-authentication/
Please let me know if you have any questions!
Thanks,
Margaret
