Psono Secrets

Psono is a self-hosted, open-source password and secrets manager built in Germany and first released in 2017. It targets teams: passwords, files, bookmarks and SSH keys are protected with client-side end-to-end encryption (Curve25519/Salsa20 via NaCl), then a TLS layer and storage encryption, with browser extensions and apps for Chrome, Edge, Safari, iOS, Android, macOS and Linux. The community edition is free; an Enterprise Edition adds LDAP/AD/SAML SSO, audit logs and commercial support, sold per user.
