Password managers compared
Password managers as their makers describe them: the company and its country, free plan, open source, and devices, with their CVE entries since 2021.
A password manager creates a different strong password for every account, stores all of them encrypted, and fills them in when you log in. You remember one main password instead of many, so it has to be long and used nowhere else. This archive adds each manager's own CVE entries since 2021. More entries do not simply mean less safety, since widely used apps are examined more closely.
