My new favorite is that my Gmail verification demands number I lost a year ago, but can still log in from trusted devices. But cannot change the number. It sends me only to FAQ, no other option given.
I added TOTP 2FA and removed phone numbers and devices from Google knowledge. Makes me a lot happier when I have to use a Google identity. My TOTP stuff doesn't need a separate app as my Password Manager hardles TOTP just fine (bitwarden, protonpass, keepassxc).
