Generate strong, random passwords in your browser. Choose length and character types. Free, no signup—nothing is sent to any server.
Strong passwords resist guessing and brute-force attacks through length, character diversity, and randomness. This generator uses the browser's cryptographically secure random number source (crypto.getRandomValues) to sample from selected character sets: lowercase, uppercase, digits, symbols. Entropy approximates log₂(charset^length); a 16-character password from 94 printable ASCII symbols offers ~104 bits — far beyond online guessing thresholds. NIST SP 800-63B recommends length ≥8 but practical guidance favors 12–16+ unique random characters or long passphrases. Passwords are created locally; nothing is transmitted to servers when used as designed. Password strength depends on length and randomness as much as symbol complexity; passphrases of four or more random words can match high entropy with easier recall when managers support them. Generated secrets should be stored in a reputable password manager with unique entries per site. Local generation avoids network exposure when the tool runs entirely in-browser as designed.
Worked example: 14-character draw from full sets might yield "K7#mQx9pL$2nRw" — estimated entropy above 90 bits, suitable for unique site credentials when stored in a password manager.

Best practices for passwords.
Longer passwords are harder to crack. For important accounts, 16+ characters with mixed types is recommended.
Include uppercase, lowercase, numbers, and symbols when the site allows it. Avoid predictable patterns like "Password1!".
Reusing the same password across sites means one breach can compromise many accounts. Use a password manager to store them.
Generated strings are only as safe as storage and uniqueness practices. Use one distinct password per site; reuse defeats randomness. Prefer a reputable password manager over memorizing many complex strings.
About the password generator.
Yes. Passwords are generated in your browser using the same cryptographically secure random API that websites use for security. No password is sent to or stored on our servers.
Yes. The randomness is suitable for real use. We recommend using a password manager to store them and never reusing the same password across different sites.
Symbols expand the character set, making brute-force attacks slower. Many sites require at least one symbol. If the site allows it, including symbols strengthens the password.
