Quick tips

  • Use 12–16+ characters (longer is generally better).
  • Prefer randomness over names, dates, or common phrases.
  • Use a unique password per site; a password manager makes this practical.

Password generator: create strong, random passwords in your browser

A good password generator helps you produce long, unpredictable strings so you are not reusing weak defaults like password123 across sites. This online password generator runs locally in your browser: your generated secure password is not sent to our servers, which supports better privacy when you experiment with length and character sets.

What makes a strong password?

Password strength usually comes from length, randomness, and character diversity. Longer passwords increase the search space against brute-force and dictionary attacks. Mixing uppercase letters, lowercase letters, numbers, and symbols (when the site allows them) makes guessing harder than using only letters. Our tool estimates strength and a rough crack time for education only—real-world risk also depends on leaks, phishing, and malware.

Random password vs passphrase

A random password from a generator is ideal for logins you paste from a vault. A passphrase (several random words) can be easier to type while staying long enough to be strong, if you pick words unpredictably. Either way, use a unique password per account so one breach does not unlock everything.

Habits that improve account security

  • Prefer 12–16+ characters (or more) for important accounts; length often beats complexity shortcuts.
  • Store secrets in a reputable password manager instead of spreadsheets or chat logs.
  • Enable two-factor authentication (2FA) where available—especially email, banking, and work accounts.
  • Avoid personal data (names, birthdays) and famous number patterns in any secure password you create.
