Information security experts recommend using complex passwords and creating a unique one for each account. Even three or four passwords are difficult to remember, so people often use the same password or similar ones. A password manager solves this problem: it generates complex passwords and stores them in a convenient form. [Bitwared](https://bitwarden.com/open-source/) can be downloaded and used on your server, which is what we use as part of the SelfPrivacy project. Unlike other free (like freedom) password managers, Bitwarden provides easy synchronization of one database between all devices.
