💡 Password Security Tips

  • Never reuse passwords across multiple accounts.
  • Avoid personal information like birthdays, names, or phone numbers.
  • Use a different password for every website and service.
  • Enable two-factor authentication (2FA) wherever possible.
  • Update critical passwords every 3–6 months.
  • Consider using passphrases — long strings of random words are both strong and memorable.

❓ Frequently Asked Questions

Is this password generator really secure? +
Yes! We use the Web Crypto API's crypto.getRandomValues() method, which provides cryptographically secure random numbers — the same standard used by security professionals and financial institutions.
Are my passwords stored on your servers? +
Absolutely not. Everything runs directly in your browser. Your passwords are never transmitted over the internet. The history feature only saves data locally on your own device using browser storage.
What is password entropy? +
Entropy measures how unpredictable a password is, calculated in bits. Higher entropy = harder to crack. A good password should have at least 60 bits of entropy; 100+ bits is considered extremely strong.
How long should my password be? +
For most accounts, 12–16 characters is a good minimum. For highly sensitive accounts (email, banking), use 20+ characters. Longer passwords are exponentially harder to crack.
What is a passphrase? +
A passphrase is a sequence of random words (like "correct-horse-battery-staple"). They are easy to remember but extremely difficult to crack due to their length.
Can I use this tool offline? +
Once the page is loaded, yes! The password generation happens entirely in your browser, so it works even without an internet connection after the initial load.
