Despite having access to the password, recovery account _and_ the telephone (when my mother is awake), I'm now locked out.
Very frustrating and a salient reminder who you should not trust Google with anything of value.
What really amazes me though is how they now treat changing recovery options as signal that the account is compromised.
Google Accounts Team: Users must have a way to recover their account!
Google Security AI: Changing recovery options is a sign of a hack! Shut it down!
Is there a new Conways Law, when an AI is involved?
