Why Use a Strong Password Generator?

Weak passwords are the leading cause of account breaches. PassGenerator uses browser-grade cryptography (crypto.getRandomValues) with Fisher-Yates shuffling to create passwords built on true entropy — not the predictable output from basic Math.random().

Our password strength meter calculates entropy in real time from your chosen character pools and length. A password scoring 70+ bits of entropy is considered strong for most accounts, while 100+ bits provides bank-grade protection against offline brute-force attacks.

How It Works

Set your password length (4–64 characters) using the slider, then toggle character types: uppercase (A–Z), lowercase (a–z), numbers (0–9), and symbols (!@#$%^&*). Enable “Exclude similar characters” to remove ambiguous pairs like il1Lo0O. The password updates instantly as you adjust any setting — no page reload needed.
