Bitwarden

Bitwarden is a password manager with an open source core for individuals and businesses. Logins, secure notes and cards sit end-to-end encrypted in a vault that only its users can decrypt. Teams get organisations with shared collections, groups, policies and event logs, self-hosted if they prefer. On top come a command line interface (CLI), a Public API for administrators and Bitwarden Send, a service for sharing text and files securely. For AI assistants, Bitwarden offers an official MCP server. MCP is an open standard that lets AI assistants use external tools.
