I can not log in to my account.
I have 2 factor authentication.
I correctly type the authentication code generated by the Google Authenticator app. Even typing the correct code appears the message in clouflare saying that I did not type the code correctly.
Try a different browser. If that doesn’t work, read on…
Did you get backup codes when you set up 2FA? Hopefully, so try one of those. If that works, disable 2FA, then re-enable it. That should refresh you 2FA Google Authenticator app.
