Error: Invalid Validation Code

  • We’ve set up the WP 2FA plugin, and the configuration worked fine, we scanned the QR code with our Google Authenticator app. When prompted for our validation code we entered it, the wizard then provided our backup codes and we completed the process. However, when we then attempt to login using the 2FA code, it continuously says “Error: Invalid Validation Code”. There are no console errors or network errors so we’re not sure what could be causing this issue. The plugin works successfully on one of our other sites and they share a hosting setup so we don’t believe it’s that. We’ve also tried clearing the cache and this didn’t fix it either. Is there some way for us to see what could be causing this issue?

    Thank you for using our plugin.

    The most common cause of “invalid codes” are time problems: the time on the device (mobile, computer, or server itself) is not in sync with the timezone configured on the system.

    Can you check the times and advise? Also, can you confirm if this problem affects all users, or only a number of users?

    Looking forward to hearing from you.

    Thank you for your response. We can confirm the server, website, and devices timezones are all in sync. It it is affecting all users.

    Thank you for the update @devteamzeal

    Is this an issue with all the users or just a number of users? Did you try creating a new user, does the issue persist?

    Or if you try to reconfigure 2FA (from the user profile page) does the issue persist?

    You can also try to use a different device, and see if that does the trick.

    Can you please advise?

    The issue is affecting all users, including newly created users. If we go into the user and reconfigure 2FA from the profile page the issue still persists. It’s happening across multiple devices. The initial setup with the first validation code in the wizard works, it only throws the error when trying to login after 2FA has been configured.
