Password Generator

A password generator is a security tool that creates strong, random passwords to protect your online accounts and sensitive data. In an era of frequent data breaches and sophisticated hacking techniques, using unique, complex passwords for every account is one of the most effective ways to safeguard your digital identity.

Our free online password generator uses the Web Crypto API (crypto.getRandomValues()) to produce cryptographically secure random passwords. Unlike many password generators that use Math.random() — which is predictable and insecure — our tool leverages the same cryptographic random number generator used by security professionals and modern encryption systems.

You can customize your passwords with adjustable length (4 to 128 characters), and toggle uppercase letters, lowercase letters, numbers, and symbols independently. The built-in strength indicator provides real-time feedback based on entropy calculation, helping you understand exactly how strong your generated password is against brute-force attacks.

All password generation happens entirely in your browser. No passwords are ever transmitted to or stored on any server, ensuring complete privacy and security. You can use this tool with confidence, even for generating passwords for your most sensitive accounts.

1. Set the password length — Use the slider to choose a length between 4 and 128 characters. Longer passwords are exponentially harder to crack; 16+ characters is recommended.
2. Select character types — Toggle which character types to include: uppercase letters (A-Z), lowercase letters (a-z), numbers (0-9), and symbols (!@#$%...). More variety means stronger passwords.
3. Check the strength indicator — The strength meter shows how resistant your password configuration is to brute-force attacks, from Very Weak to Very Strong.
4. Click Generate — Press the Generate Password button to create a new random password with your chosen settings.
5. Copy your password — Click the Copy Password button to copy it to your clipboard, then paste it into your password manager or account registration form.
