Password Centinel

Password Centinel is now active in your browser. A fully local password manager: encryption, TOTP and breach checking

Password Centinel

Quick start

  1. 1

    Create your vault

    Set a master password; your vault is encrypted locally with AES-256-GCM from the very first second.

  2. 2

    Save and generate

    Add existing credentials or generate secure passwords and passphrases on the fly.

  3. 3

    Check and protect

    Analyze strength and check for breaches (HIBP) without your password ever leaving the browser.

Password Centinel

Worth knowing

  • AES-256-GCM encrypted vault

    Key derived from your master password via PBKDF2 (100,000 iterations, SHA-256). The master password never leaves browser memory.

  • Built-in TOTP / 2FA

    Generate one-time codes directly from the vault, with no external app required.

  • Breach checking (HIBP)

    Uses the Have I Been Pwned k-anonymity model: only 5 characters of a SHA-1 hash are sent, never your password.
