I am trying to setup the two factor authentication on my Firefox account, but it does not seem to work. I read the QR code into the authentication app (I have tried Google Authenticator, and andOTP), but the security code it gives is not accepted for various reasons - usually it plainly says invalid code. What could be the issue?
Let’s hope someone else will learn from my mistake. It was an NTP issue, I was off by a minute
