Entering your Google Authenticator 2FA code correctly and having it rejected is a heart-pounding experience. Here is what you can do:
- Make sure the “Google Authenticator” app is installed on your Mobile phone.
- Make sure both the time/clock on your mobile phone and the computer is synchronized.
The culprit is usually the clock setting on your phone, which can easily bring 2FA crashing to a halt. 2FA codes time out after just two minutes, and if the clock on your phone has “Automatic time zone” and “Automatic date & time” switched off, you’re at risk of instantly timing out and encountering the dreaded 2FA fail.
