You cannot hash passwords in a password manager. It has to be reversibly encrypted and turned back into plain text before utilisation.<p>So when people complain about password managers storing plain text (as opposed to hashing) they&#x27;re barking up the wrong tree, it is a necessary evil.<p>You just want to see them encrypt those plain text passwords so that offline recovery is harder. That&#x27;s what both Firefox&#x27;s master password, CryptProtectData() for Chrome&#x2F;IE, and the key-chain in OS X provide.
