So out of curiosity, what password manager do you use? And as apparently you don’t trust your password manager, why do you use one? And how do you determine what is “useless” enough to be entrusted to that password manager you do not really trust?
I trust everything I use to some degree. Otherwise I wouldn't use it in the first place. But the world is not black and white.
Just because I trust something enough to store secret X in it, doesn't mean I should automatically use it to store secret Y.
