Psono

Psono is an open-source, self-hosted password manager with a strong emphasis on team functionality. It offers client-side encryption, secure sharing of passwords, files, and bookmarks within teams, and support for YubiKey hardware tokens. The server code can be deployed on-premise, giving organizations full control. A free hosted version is available with limited features, while paid hosted plans and enterprise self-hosted licenses unlock more storage and users.

Its interface is functional rather than beautiful. It's a compelling option for European companies concerned with data sovereignty, tech collectives, and any team that prioritizes open-source software and self-hosting for their credential management.
