Psono
EU verifiedOpen-source password manager from Germany with client-side end-to-end encryption – self-hostable or as SaaS.
Psono (esaqa GmbH) is an open-source password manager for teams and companies. Passwords and secrets are end-to-end encrypted on the client side, so the server only stores encrypted data. The server is open source and can be fully self-hosted – for maximum data sovereignty – or used as a hosted SaaS. For businesses, Psono offers SAML/LDAP integration, audit logs and sharing; the self-hosted community edition is free. Security audits (e.g. by Cure53) are publicly available.
Note on ownership: Open-source password manager by esaqa GmbH (Vorra, Bavaria), founded by Sascha Pfeiffer. The server code is open source and can be fully self-hosted; alternatively there is a hosted SaaS. At its core is client-side end-to-end encryption – passwords are encrypted and decrypted in the browser and the server only sees encrypted data. When self-hosting, the data stays fully under your own control.
