Generate strong random passwords with custom options

Password Generator — Generate Strong, Secure Random Passwords Online

  1. Configure your password requirements: set the length (recommended: 16+ characters), and choose character sets to include — uppercase letters (A-Z), lowercase letters (a-z), digits (0-9), and symbols (!@#$%^&*).
  2. Click Generate to create cryptographically secure random passwords using the browser's built-in Crypto.getRandomValues() API — the same entropy source used by SSL/TLS encryption. The generator ensures at least one character from each selected set.
  3. Copy the generated password and use it for your accounts. The tool displays a strength meter that evaluates entropy, length, and character diversity. Generate multiple passwords at once for batch account setup.

Frequently Asked Questions

Is the Password Generator free?

Yes, completely free. Generate unlimited passwords — no limits, no tracking, no account needed.

Are my generated passwords uploaded or stored anywhere?

No. Passwords are generated entirely in your browser using the Web Crypto API. They are never transmitted, stored, or logged — not even in your browser's local storage. The password exists only in your clipboard after you copy it.

What makes a password truly strong and how should I manage passwords securely?

A strong password has three properties: (1) Length — this is the most important factor. A 16-character random password has about 10^30 possible combinations, making brute-force attacks infeasible. Each additional character multiplies the search space by the character set size. (2) Character diversity — using all four character sets (upper, lower, digits, symbols) maximizes entropy per character. (3) Randomness — human-chosen passwords follow predictable patterns (keyboard walks, dictionary words with number substitutions). Use a cryptographically secure random generator like this tool. Best practices: use a unique password for every service (password reuse is the #1 cause of account compromise), use a password manager (Bitwarden, 1Password, or browser-built-in) to generate and store passwords, enable two-factor authentication (2FA/TOTP) wherever possible, and never share passwords via email, chat, or unencrypted channels. For maximum security, use passphrases (e.g., "correct-horse-battery-staple") — they are easier to remember and type while maintaining high entropy.
