Secure Password Generator

A secure password generator creates passwords suitable for protecting sensitive accounts and data — using cryptographically secure randomness, full character sets, and lengths that resist both brute-force and dictionary attacks. All generation runs client-side with no transmission of any kind.

    🔒 Passwords are generated in your browser and never transmitted to any server.

    What makes a password generator "secure"?

    Security comes from the randomness source. PassFortify uses crypto.getRandomValues(), the Web Cryptography API's CSPRNG (Cryptographically Secure Pseudo-Random Number Generator). This is the same standard used by TLS, SSH key generation, and encryption libraries. Math.random(), used by many sites, is NOT cryptographically secure and should never be used for passwords or keys.

    Secure passwords and password managers

    A secure password generator is most powerful when paired with a password manager like Bitwarden, 1Password, or KeePass. The manager stores unique passwords for every account, so you only need to remember one strong master password. Generate 16–24 character passwords for all your accounts, and use a 6-word passphrase as your master password.

    Frequently Asked Questions

    A CSPRNG (Cryptographically Secure Pseudo-Random Number Generator) generates numbers that are statistically indistinguishable from true random numbers and are unpredictable even if previous outputs are known. The browser's crypto.getRandomValues() API provides CSPRNG output seeded from OS-level entropy sources.

    Yes, when it uses crypto.getRandomValues() as PassFortify does. The security depends entirely on the randomness source — not on whether it runs in a browser. Browser-based generators are actually more private than server-side ones because nothing is transmitted.

    Use a reputable password manager: Bitwarden (open-source, free), 1Password, or KeePass. Never store passwords in plain text, browser notes, or spreadsheets without encryption.

    With all character types (94 characters), a 16-character random password has ~105 bits of entropy. This exceeds all current security recommendations and is effectively uncrackable with modern hardware.
