Online Password Generator — Strong Random Password Generator
What is a Password Generator?
A password generator is a tool that creates random, secure passwords using cryptographically strong random number generation. Unlike human-created passwords that tend to follow predictable patterns, generated passwords are truly random and include a mix of characters that makes them extremely difficult to crack.
Our password generator uses crypto.getRandomValues() — the same cryptographic API used by security professionals — to ensure your passwords are as random and secure as possible.
Why Use Our Password Generator?
- Cryptographically secure — Uses
crypto.getRandomValues()for true randomness, not Math.random() - Fully customizable — Choose character length (6-64), uppercase, lowercase, numbers, and symbols
- 100% private — Passwords are generated locally in your browser. Never transmitted anywhere.

Frequently Asked Questions
Are the passwords truly random?
Yes. We use crypto.getRandomValues(), a cryptographically secure pseudo-random number generator (CSPRNG) built into modern browsers. It is significantly more secure than Math.random().
Are my generated passwords stored or logged?
No. Everything happens in your browser. The generated password is never saved, sent to a server, or stored anywhere. Once you close the page, it's gone.
What makes a password strong?
A strong password is long (16+ characters), random, and includes a mix of uppercase letters, lowercase letters, numbers, and special symbols. The passwords generated by this tool meet all these criteria.
Can I generate passwords on my phone?
Yes. The tool is fully responsive and works on all modern mobile browsers.
