I like also that you can encrypt your password file with an additional passphrase, so that even if somebody manages to get through all the hurdles to gain access to your account, they still have to brute force their way into your saved passwords. With a sufficiently long and complex enough passphrase, this is nearly impossible. 

I haven't found a password manager that's both as secure and convenient as just storing them all in my Google account.

If somebody were able to gain access they could PWN my entire life, but the risk is high severity, low probability, IMO.
