Free Password Generator Online
Generate strong, random, secure passwords instantly. Customize length, characters & complexity. No data saved — ever.
🔒 What is a Password Generator?
A Password Generator creates random, secure passwords that are extremely hard to crack. It uses a combination of uppercase, lowercase, numbers, and symbols to maximize security.
Weak passwords like “123456” or “password” are cracked in under 1 second. A 16-character random password would take billions of years to crack by brute force.
Our tool uses cryptographically secure randomness (via browser’s Web Crypto API) — so every password is truly random.
🚀 How to Use
- Set your desired password length using the slider (16+ recommended).
- Toggle which character types to include (uppercase, lowercase, numbers, symbols).
- Click “Generate Password” to create a secure password instantly.
- Click “Copy” to copy it to clipboard or regenerate as many times as you want.
- Use “Generate 10 Passwords” to bulk create options and pick your favourite.

Yes. Our tool uses the browser’s built-in Web Crypto API (window.crypto.getRandomValues) to generate passwords. This is the same cryptographic standard used by security professionals and is considered truly random — far superior to Math.random(). Your passwords are never sent to any server.
Security experts recommend at least 12–16 characters for most accounts. For highly sensitive accounts (email, banking), use 20+ characters. A 16-character password with mixed characters would take billions of years to crack by brute force. Our tool defaults to 16 characters as a best-practice starting point.
Absolutely not. Password generation happens entirely in your browser using JavaScript. No passwords, no settings, no data of any kind is ever transmitted to our servers or any third party. Your security is completely in your own hands.
Enable all four character types: uppercase + lowercase + numbers + symbols. This gives the largest possible character pool (94 characters), making passwords exponentially harder to crack. A 16-character password with all types has more combinations than there are atoms in the observable universe.
Some characters look very similar and can cause confusion when reading or typing a password manually — for example: i, l, 1, |, O, 0, o. Enabling this option removes these characters, making your password easier to read and type without sacrificing much security.
