Browse allWhat Is a Password Generator?
A password generator creates long, random strings from letters, numbers, and symbols so you do not rely on guessable words or reused logins. Strong passwords are long and unpredictable.
Why Client-Side Matters
This tool uses window.crypto.getRandomValues in your browser. The password is never uploaded. Prefer offline generators over sites that send secrets to a server.
Frequently Asked Questions
How long should a password be?
Aim for 16+ characters with a mixed charset for most accounts; longer is better for high-value logins.
Passphrases vs random passwords?
Random strings maximize entropy per character; long unique passphrases can also be strong if truly random and unused elsewhere.
Is this password generator safe?
Yes for privacy — generation is client-side only. Still store passwords in a manager and enable 2FA where possible.
Should I use special characters?
When sites allow them, symbols enlarge the charset and strengthen shorter passwords.
Is this password generator free?
Yes — free, private, no signup.
