My phone once died at work and I needed to write my gf. While I had my phone in the charger I thought I could just do it on my work PC (HA! What a funny joke).
"Check your phone. Can't do that? Check your email."
I try to log into my email.
"Lol, check your phone."
2FA: Literally my case here, too bad my email also had 2FA pointed towards my phone.
And I don't have my personal password manager on my work computer. Not to mention it wouldn't save me from this 2FA chain that makes me phone the only valid key.
The moral of the story is ofc don't use Gmail or stuff that only trusts your bloody phone.
It makes me do the three-number selection thing like 2-3 times. One time, after completing it correctly (3 times in a row, mind you), it still blocked my login.
I am very fearful of the day I just can't login to my account anymore.
