Passwords are generated locally in your browser — never sent to any server.

How to use
Adjust the length slider (6–64 characters) and toggle character sets: uppercase letters (A-Z), lowercase letters (a-z), numbers (0-9), and symbols (!@#$%^&*). A strong password is generated instantly with every change. Click Copy to copy to clipboard, or Regenerate to get a new password with the same settings.
Why use this tool
Weak passwords are the leading cause of account breaches. This generator uses the browser's Web Crypto API (cryptographically secure random number generation) to create passwords that cannot be predicted. Unlike server-based generators, your passwords are created entirely locally — they are never transmitted to any server, logged, or stored.
FAQ
- Are the generated passwords sent to your servers?
- No. Passwords are generated entirely in your browser using the Web Crypto API (window.crypto.getRandomValues). Nothing is ever transmitted to any server. You can even disconnect from the internet and the tool will still work.
- What makes a password strong?
- Length and character variety. Use at least 12–16 characters with a mix of uppercase, lowercase, numbers, and symbols. A 16-character random password from all character sets would take centuries to brute-force with current hardware.
- How long should my password be?
- At minimum 12 characters for general accounts, 16+ for important accounts (email, banking, work systems). For service accounts or API keys, use 32+ characters. Longer is always better.
- Why include symbols in a password?
- Adding symbols expands the character set from 62 (letters+digits) to ~90 characters, making brute-force attacks exponentially harder. A 12-character password with symbols has ~10^23 possible combinations.
- Can I generate multiple passwords at once?
- Click Regenerate repeatedly to get a new password each time. Each click uses cryptographically secure randomness.
- Is this tool safe to use for real passwords?
- Yes. The Web Crypto API is the same standard used by password managers and security tools. The local-only generation means there is no risk of interception.
