Password Generator — Strong Random Password Maker with Strength Meter (HTML/CSS/JS)

PassGen — Free Password Generator with Strength Meter

Weak passwords are the #1 reason accounts get hacked — yet most people still reuse the same simple password everywhere. PassGen fixes that in one click: it creates strong, random passwords instantly, shows how strong they really are, and never sends anything to a server.

Features

• One-click strong passwords: Generate random passwords from 4 to 64 characters with a length slider.
• Full character control: Toggle uppercase, lowercase, numbers and symbols — plus an option to exclude ambiguous characters (0, O, 1, l, I).
• Live strength meter: Entropy-based rating from Very Weak to Excellent, so you know exactly how secure a password is.
• Crack-time estimate: See roughly how long a password would survive an offline brute-force attack.
• One-click copy: Copy any generated password straight to the clipboard.
• Recent-password history: Last 5 passwords kept on the page — click any entry to reuse it.

What's Inside

index.html, style.css, app.js and a full README.txt (setup + customisation guide). Pure HTML, CSS and JavaScript — no libraries, no build step, no database.

How to Use

Unzip the file, open index.html in any modern browser, set your length and character options, click Generate Password, then Copy. To host it, just upload the folder to any static or PHP hosting.

Security Note

Passwords are generated with the browser's cryptographically secure crypto.getRandomValues() (with rejection sampling to avoid modulo bias) and never leave the visitor's device.
