Password managers

• syspass — PHP, MySQL; installable (Docker, standalone); questionable security model (shared master password which needs to be told to every user); extensive initial setup (there are no default policies and so on); confisung terminology (their use of the term “account” is quite contradictory and leads to misunderstanding)
• Passbolt — installable (Docker); requires browser extension which basically makes it unusable

• SuperGenPass — predictable algorithmic password generator as a browser bookmarklet (alternatives)
• clipperz — Python; is an online service, there is a source code for self-hosted, but it lacks security features (alternatives)

Directly use KeePass databases (*.kdbx)

• KeeWeb — web-version of KeePass installable (self-hosted HTML file); I was unable to use Dropbox support
• AuthPass — serous problems with Debian repository setup (effectively can't install)

• Passit — online and self-hosted; Python, PostgreSQL; decent security model; requires public domain name and public SSL certificate, at least for the Docker installation (alternatives)
• passman (alternatives)
• Psono — requires public domain name and public access
