You thought knowing and maintaing strong password is enough to guarantee access. Well Google disagrees with you.
If migrate to a different country and dont have access to your old number you will be in world of pain.
Getting access to anything is suddenly hell. I explicitly disabled 2FA after encountering this bullshit once. Won’t risk losing my account again.
Personally I've also got it floating around one of my Linux devices with a small program I can run against it to display the codes, which came in handy when I switched phones and forgot to reload the GA app. (Yes, I know that this defeats some of the security of the second factor, with it supposedly being "something you have" that can't be easily reproduced).
I’ve almost lost my Google account twice in less than a year due to Google’s terrible 2FA implementation.
I’ll take my chances thank you.
