Random Password Generator
Create strong, cryptographically secure passwords with your choice of length and character types.
Why Use a Password Generator?
Human-chosen passwords tend to follow predictable patterns — dictionary words, names, and simple substitutions like "p@ssw0rd". An attacker using a list of common passwords can crack these in seconds. A randomly generated password with a mix of character types has no pattern and requires brute-force enumeration, which is computationally infeasible for long passwords.
This generator uses the browser's built-in Web Crypto API (crypto.getRandomValues) rather than the less secure Math.random(), ensuring your passwords are cryptographically random.
Frequently Asked Questions
How random are the generated passwords?
Passwords are generated using the Web Crypto API's crypto.getRandomValues(), which produces cryptographically secure random numbers. This is far more secure than Math.random().
What length password should I use?
Security experts generally recommend a minimum of 12 characters for most accounts, and 16 or more for important accounts such as email, banking, or password managers.
Are my passwords stored or transmitted?
No. Password generation happens entirely in your browser using JavaScript. Nothing is sent to any server, and no passwords are ever stored.
What makes a strong password?
A strong password is long (12+ characters), unique to each site, and uses a mix of uppercase, lowercase, numbers, and symbols. Using a password manager to store generated passwords is strongly recommended.
Can I use this for Wi-Fi passwords?
Yes. For Wi-Fi passwords, avoid symbols that may be difficult to enter on TV or games console keyboards (like | or "). Using 16 characters with letters and numbers is a good balance of security and usability.
