About PassForge

A fast, private, client-side password generator with no strings attached.

How it works

Every password PassForge generates runs entirely inside your browser — no data is ever sent to a server. The generator uses the Web Crypto API:

crypto.getRandomValues(new Uint32Array(length))

This API is built into every modern browser and provides cryptographically secure random numbers seeded by the operating system — the same source of randomness used by security software and password managers.

Privacy by design

PassForge has no backend. There is no database, no user accounts, and no API that receives your passwords. The page loads once, and after that everything happens locally in JavaScript.

We use Google Analytics to measure aggregate traffic (page views, not password contents). No personally identifiable information is collected, and we never log any generated passwords.

Why client-side generation matters

Many password generator websites secretly log the passwords they generate — or could, if their server were compromised. Client-side generation eliminates this attack surface entirely:

No server-side logging — Your password is never transmitted, so it cannot be intercepted or stored.

No supply-chain risk — A compromised CDN or server cannot inject a keylogger that phones home.

Auditable — The source code is straightforward JavaScript you can read in DevTools.

Understanding password strength

PassForge measures strength in entropy bits. Entropy is calculated as:

bits = log₂(pool_size ^ length)

Each additional bit doubles the number of guesses required to brute-force the password. A 16-character password with all character sets enabled achieves approximately 100 bits of entropy — more combinations than atoms in the observable universe.

Strength	Entropy	Verdict
Weak	< 40 bits	Avoid
Fair	40–59 bits	Low-value accounts only
Strong	60–79 bits	Good for most uses
Very Strong	80+ bits	Excellent

How PassForge compares to built-in generators

Most password generators you encounter are bundled inside password manager marketing pages. They work, but they come with trade-offs.

Generator	Client-side?	No tracking?	Ad-free?
PassForge	Yes	Yes	No (ads below the fold)
LastPass Generator	No	No	Yes (upsell funnel)
1Password Generator	Yes	No	Yes (upsell funnel)
Bitwarden Generator	Yes	Yes	Yes (account required)
Norton Generator	No	No	No

We're honest: PassForge shows ads. The difference is they're below the fold and don't interrupt the tool. We're not here to sell you a subscription — just to give you a fast, trustworthy generator.
