Passbolt

Passbolt is an open-source password manager designed for teams and enterprises with strong security requirements. It uses GPG-based end-to-end encryption, ensuring only authorized users can access shared passwords. Features include secure password sharing, role-based access control, LDAP/AD integration, audit logs, and browser extensions. Passbolt is audited for security and complies with regulations like GDPR. It's ideal for organizations that need enterprise-grade password management with complete control.

Passbolt runs on PHP with a MySQL/MariaDB database and requires a GPG keyserver component. The application handles user authentication, key management, encrypted password storage, and permission enforcement. Resource usage scales with the number of users, passwords, and concurrent access. Background tasks handle email notifications and health checks. The GPG operations are CPU-intensive during user registration and key operations.
