About PassGens

What Is PassGens?

PassGens is a free, browser-based tool for generating strong passwords and unique usernames. It was built with one goal: make it easy for anyone to create secure credentials instantly, without handing over personal data or creating yet another account somewhere.

Everything runs locally in your browser. No servers receive your passwords, no databases store your data, and no trackers follow you around. Close the tab and everything is gone.

What Can It Do?

• Generate strong, random passwords up to 64 characters
• Generate unique usernames from a curated word list
• Generate a username and password together in one click
• Customise passwords with length, character types, and exclusion rules
• Check the strength of any existing password with the built-in Strength Checker
• See entropy scores and estimated crack times in plain English

Why We Built It

Most people still use weak, reused passwords — not because they don't care about security, but because creating a strong password for every account is inconvenient. PassGens removes that friction. One click, one strong password, ready to use. No signup, no tracking, no cost.

Privacy First

PassGens uses the Web Cryptography API (crypto.getRandomValues) for all password generation — the same cryptographic standard used in professional security software. Nothing you type or generate here ever leaves your device. For full details, see our Privacy Policy.
