I’m disappointed(?) that this didn’t really have anything that seems to differ from password managers in general.
But that does not mean this study should be dismissed. Just because they didn’t find new and exciting ways to be horrible that aren’t analogous to passwords in password managers, it doesn’t mean it was worthless to look into it.
Also, if I’m wrong, and the situations described can’t just all have a password manager swapped in, then please correct me!
I guess if someone isn’t using a password manager, and is managing to remember all their passwords, or keep them safe in the physical world somehow, passkeys are worse.
