How Bitwarden Works

End-to-End Encryption by Default

Vault items are encrypted locally using strong, modern cryptography. Your master password never leaves your device. Only encrypted ciphertext is transmitted and stored, enabling a true zero-knowledge model.

• Keys derived with industry-standard KDF and configurable iterations
• Items remain encrypted at rest and in transit
• Open source codebase for transparent verification

Collections and Secure Sharing

Create collections for teams, projects, or clients. Share credentials, notes, and files without pasting secrets into chat or tickets. Assign roles and policies to keep access least-privileged.

Audit Trails and Breach Monitoring

Track changes with exportable audit logs. Monitor exposure using leak and breach alerts to proactively rotate credentials.

Self-Hosting Options

Run Bitwarden with Docker and maintain full control over data locality and lifecycle. Admin tools streamline backups, upgrades, and high availability configurations.
