Set the length (4–128 characters) and choose which character types to include: uppercase, lowercase, numbers, and symbols. Click "Generate Password" to create a strong random password. Copy it and use it in a password manager or for a new account. Generation runs in your browser and nothing is sent to any server.
About Password Generator
Weak or reused passwords are a leading cause of account breaches. A random password generator creates strong, unique passwords that are hard to guess or crack by brute force. This tool uses the browser's secure random source (Web Crypto API) so the passwords are cryptographically random. Nothing is sent to a server — generate and copy locally, then store in a password manager for best security.
How to Use Password Generator
- Set Length (e.g. 16 or 20). Longer is stronger; 12–16 is a common minimum.
- Check the character types you want: uppercase, lowercase, numbers, symbols. Including all four increases strength.
- Click Generate Password. Copy the result and paste it into your password manager or account signup. Generate again if you need a new one.

Technical Details
Randomness comes from crypto.getRandomValues(), which is backed by the operating system's cryptographic random number generator. This ensures output suitable for security-sensitive applications. Always use a password manager to store and fill passwords. Check strength with our Password Strength Checker or measure entropy with the Password Entropy tool. For more memorable passwords, try the Passphrase Generator.
