Google security allows you to use a titan key, but then still ignores it if you use an android phone, not the best security, since phones can get sim jacked. (common way to get your ecoins hacked, take over your phone.) Defeats the purpose of a titan key and 2fa enabled. There is no option to turn off android auth confirmation popups, so you have to de-activate all signed in google phones, and remove google account on your cell for more security and stop trolls from spamming you, if your phone number is public. People been asking google for years to fix this major fubar. Google auth is designed by idiots, to be as easy as possible, but bad actors can abuse.
