Google has a new account setting called Advanced Protection. All it accepts is two hardware U2F keys (primary and backup) and your password. It supposedly makes your Google account pretty hardened. The only issue is that you can only use Chrome with U2F keys right now because Firefox U2F isn't fully baked yet. I'm using it with the Titan keys (they're not my favorite, but work) and it works pretty well. I can't do as much 3rd party stuff, but I only keep my Google account (right now) for my old email address that's already forwarded to my new email address, Google Music, and Google Pay, so that doesn't affect me much. If you use a lot of 3rd party apps or get your mail via IMAP and the like, it's going to be more difficult. A weird thing is that Google doesn't seem to allow for U2F key use without Advanced Protection turned on, which is puzzling to me.
