2FA/MFA isn’t the problem. Google is just a pain to deal with when their products don’t work as expected. On one hand, security-wise, it’s good that they tend to design their algorithms to err on the side of being restrictive, but on the other hand, they have no legit support, so if you or their algorithms mess up and you’re locked out of your account, you’re basically on your own. For a company so many of us rely on so deeply, that’s awful!
