2FA: One Time Password (OTP) was not valid. Please try again.

Hello. After installing Shield and setting up 2FA via mail and Authenticator, I have found two issues with this plugin.

My system requires me to have a “mobile device friendly” OTP as a primary 2FA solution, and “secondary OTP solution” for other devices used to log in, and Shield seemed like the perfect solution:

For Mobile as primary – Google Authenticator via app or Authy, and mail 2FA as a secondary method. The settings are as follows:

Google Authenticator ENABLED

Email Authentication ENABLED

Now I have two problems: I do not want to ENFORCE (as I understand – make primary) the mail OTP, but if I deselect roles from the “enforce email authentication”, no OTP is required and users can login with username/password only, even though Authenticator is Enabled.

But, when I try to add Google Authenticator data, scan the QR code and do everything by the plugin documentation, I only get this message: One Time Password (OTP) was not valid. Please try again.

I have tried it over several different accounts and devices, none seem to work.

Please help me out here.

Thank you.
