About Password Rangers

Password Rangers is a small independent site offering free password generators that run entirely in your browser. Every password, passphrase, and PIN is created on your own device using the Web Crypto API. Nothing you generate is ever sent to a server, and you can verify that yourself in your browser's DevTools.

What this site is

Password Rangers launched in 2026 as a collection of free password tools that need no account and store no passwords. The main strong password generator lives on the homepage, with focused tools for Wi-Fi passwords, passphrases, PINs, and bulk generation.

Alongside the tools, we publish short, plain-English guides on password security. They answer the questions people actually search for, like how long a password should be, without padding or scare tactics. There's also a strength checker on the homepage if you want to test something you already use.

Why we built it

We built Password Rangers because most top search results for password generators are marketing pages for subscription password managers. The generator is the bait, the funnel is the product. We wanted the opposite: the tool by itself, with no account, no upsell, and no password ever touching a server.

To be clear, password managers are genuinely useful, and our guides recommend using one. But you shouldn't have to walk past a sales pitch to get twenty random characters. A generator is a small, well-understood piece of software. It should be free, fast, and honest about how it works.

How the generator works

Every password comes from crypto.getRandomValues, the Web Crypto API function browsers provide for cryptographic randomness. We apply rejection sampling to remove modulo bias, so each character in the pool has exactly the same chance of being picked. Generation makes zero network requests, which you can confirm in the DevTools Network tab.

Strength estimates are shown honestly, in bits of entropy, using a fixed attack model: an offline attacker making 10 billion guesses per second, cracking in the average case (half the keyspace). We'd rather show you a sobering number than a comforting one. The code runs in the page itself, so anyone can inspect the source, and the tools keep working offline once the page has loaded. If you're wondering how any online generator can be trusted, we wrote a guide on exactly that: are online password generators safe.

Our editorial standards

Our guides are grounded in two public standards: NIST SP 800-63B, the US federal guideline on digital identity, and CISA's Secure Our World program. When we cite a number, like the 15-character minimum NIST recommends for accounts protected by a password alone, we link the source so you can check it.

Security advice goes stale. When these standards move, we update the affected pages and date the updates, so you can tell whether what you're reading reflects current guidance. Every crack time we publish comes from the same entropy math the tools use, not from a headline we found somewhere.

How the site is funded

Advertising on our informational pages keeps the tools free. That's the whole model: no subscriptions, no premium tier, no affiliate commissions pushing you toward any product. Ads never influence what the generators do, and because everything runs in your browser, we never see a single password you create.

There's nothing to see even if we wanted to look. Generation happens on your device, and no generated value is ever transmitted, logged, or stored by us. An advertiser can buy space on a guide page. They can't buy a change to the tools.

Contact us

Questions, corrections, or bugs are always welcome. The fastest route is the contact page, or you can email [email protected] directly. We read everything, and reports of factual errors in the guides get fixed first. If a number on this site is wrong, we want to know about it.
