> After going through these, it seems to me that the likelihood of a security lockout is low enough not to worry about [...] I disagree. I've managed to get locked out twice now. The first time I have no idea what happened. Google just disregarded the correctly completed email-verification and security questions and just said "no". I retried a month later and was able to log in. The second time, I logged in from an university-owned Android phone. Despite not even being an admin on that phone, Google decided that it would now be my only permitted 2FA method, and so, when I tried to log in away from university, I was locked out.
