> more than one password manager
I'm sorry, what? Who has more than one password manager (other than a personal/work split)? That's absurd and not something anyone I've heard of would put up with
It's not that hard. Chrome and something else. (Such as iOS.) A different kind of backup authentication method would work too.
if I can't have two password managers for redundancy then none it is.
Want to guess how many non-tech individuals save passwords in Chrome on desktop and in iOS on their iPhone?
