I don't think password managers which store encrypted vaults are less safe than trying to have and juggle strong unique-per-domain passwords, even if you think that the password manager is becoming a target.
I do think there are some cases where an online password manager makes sense, e.g. for businesses, but for individuals it's better to just stick with an offline password manager, at least for the high value accounts.
But if even that is too much then f.ex. `keepass` + a scheduled script to periodically backup to your own servers is also perfectly viable.
Wait. That's a thing? Like, there are drooling, mouth-breathing stooges out there that would trust not just one of their passwords to such a thing, but all their passwords to it?
And it's not unheard of that infections metastize, whether into developer accounts, product code... Probabilistically, this was a shot on goal.
I apologize for the mixed metaphors.
For backup, the hardware security key let's you download a file from it with all of your passwords encrypted, and the decryption password it's shown on it's screen (something like 12 random words)
