Open‑source password manager with all core features free forever. Unlimited passwords, cross‑platform sync, TOTP generation, password strength auditing. End‑to‑end encrypted and self‑hostable.
Password leaks are a top cybersecurity threat. Bitwarden generates strong random passwords and stores them securely—all data is encrypted locally before syncing to the cloud. Unlike commercial managers, Bitwarden’s free tier is nearly unlimited, and open‑source code ensures transparency.
We analyzed Bitwarden’s encryption. It uses PBKDF2 or Argon2id key derivation, AES‑256 encryption, and the master password never leaves your device. Even if servers are compromised, plaintext passwords remain safe. Two‑factor authentication (via Authy, etc.) is supported.
Independent security audits and a bug bounty program keep Bitwarden safe. A 2024 third‑party audit found no critical vulnerabilities.
Pro tip: Enable 2FA—even if your master password is leaked, attackers can’t log in. Bitwarden supports hardware keys (e.g., YubiKey) as a second factor for maximum security.
