One Time Password issue (?)

[greY]

I'm following this guide to configure a two-factor authentication
https://docs.opnsense.org/manual/how-tos/two_factor.html

After it I'm going to System >> Access >> Tester and always get an "Authentication failed." message.

Can anybody confirm that two factor authentication is working? I'm using this app https://play.google.com/store/apps/details?id=com.google.android.apps.authenticator2

Nobody is using OTP?

greY, did you get it to work?
I have same problem.

UPDATE:
You have to type the google code + user's password
