About PassFortify

PassFortify is a free suite of browser-based cybersecurity tools built on a single principle: privacy first. Every tool runs entirely in your browser — no data is transmitted, stored, or logged.

Our mission

We believe that strong security tools should be accessible to everyone — without requiring subscriptions, account creation, or trusting a third party with your sensitive data. PassFortify provides professional-grade security tools that run 100% client-side, meaning your passwords, secret keys, and email addresses never leave your device.

In a world where data breaches are common and credential theft is the leading cause of account takeovers, the best security tools are those that generate no new attack surface. PassFortify has no server, no database, and no user accounts — there is nothing to breach.

How our tools work

All PassFortify tools are built with vanilla HTML, CSS, and JavaScript. They use the browser's built-in Web Cryptography API exclusively:

Password generation uses crypto.getRandomValues() — the same CSPRNG used by TLS, SSH key generation, and encryption libraries.
TOTP generation uses crypto.subtle.sign() with HMAC-SHA1 — a standard Web Crypto operation with no external dependencies.
Breach checking for passwords uses crypto.subtle.digest() to hash passwords locally — only 5 characters of the hash are sent via k-Anonymity.
We never use Math.random() for anything security-related.

Our security principles

Zero data transmission — Passwords, passphrases, secret keys, and strength check inputs never leave your browser.
Cryptographically secure randomness only — We use crypto.getRandomValues() exclusively. Never Math.random().
No accounts, no tracking — No user registration, no login, no behavioral tracking. Google AdSense is used for monetization with standard ad cookies.
Open for AI indexing and citation — Our llms.txt and robots.txt explicitly welcome AI crawlers. We want security facts to be freely citable.
Free forever — Core tools will always be free. Security shouldn't be paywalled.
