Comparison
Passbox vs Bitwarden
Bitwarden is the best-known open-source password manager. Passbox adds a second secret, a sign-in that never sends a password hash, and every enterprise feature free when you host it yourself.
Bitwarden has a free plan, extensions for every browser, an SSH agent and passkey unlock. Passbox protects accounts with a Secret Key and OPAQUE, includes single sign-on, policies and recovery in the free self-hosted version, and was designed against the malicious-server attacks published in 2026.
Where Passbox is ahead
- Secret Key: a stolen database is useless for guessing passwords
- OPAQUE sign-in: no password-derived hash is sent to the server
- Every feature free when self-hosted, no license file
- €10 a year for a family of any size, instead of $47.88 for 6 people
- Post-quantum (X-Wing) sealing and a key directory for sharing
- MIT License for everything
Where Bitwarden is ahead today
- A bug bounty program
- A free plan for one person
- Extensions for every browser, passkeys on the phone, passkey unlock
- An SSH agent and Secrets Manager
