Generate Strong Passwords Instantly
Create secure, random passwords in seconds by choosing a preset and adjusting the length and character set.
Everything runs directly in your browser using a cryptographically secure random generator — no data is sent anywhere, and no passwords are stored.
What Makes a Password Strong?
A strong password is long, random, and unpredictable — it doesn't rely on real words, personal information, or common patterns that attackers can guess.
Password strength is measured in bits of entropy: the more possible combinations a password could be, the longer it would take to crack by brute force.
Why Use a Password Generator?
Humans are bad at creating truly random passwords — we tend to reuse patterns, dates, and words that are easier to guess or that appear in leaked password lists.
A password generator removes human bias entirely, producing passwords that are far more resistant to guessing, dictionary attacks, and brute-force attempts.

Password Strength Guide
| Below 40 bits | ❌ Weak — easy to crack |
| 40–64 bits | ⚠️ Medium — acceptable for low-risk accounts |
| 64–100 bits | ✅ Strong — good for most accounts |
| 100+ bits | ✅ Very strong — ideal for critical accounts |
Password Best Practices
Use a unique password for every account — reusing passwords means one leaked account can compromise many others.
Store your passwords in a reputable password manager instead of memorizing or writing them down.
Enable two-factor authentication (2FA) wherever possible for an extra layer of security beyond the password itself.
Common Password Mistakes to Avoid
Avoid using personal information such as names, birthdays, or pet names — these are often guessable or discoverable.
Avoid short passwords or simple patterns like "123456" or "password" — these are the first passwords attackers try.
Avoid reusing the same password across multiple websites, especially for email and financial accounts.

Frequently Asked Questions
Are these passwords truly random?
Yes. Passwords are generated using your browser's cryptographically secure random number generator (Web Crypto API), not a predictable pseudo-random function.
How is password strength calculated?
Strength is measured in bits of entropy based on the password length and the size of the character set used. More bits mean more possible combinations and better resistance to brute-force attacks.
Can I use the same generated password for multiple accounts?
No. Each account should have its own unique password so that a breach on one site doesn't put your other accounts at risk.
Where are my generated passwords stored?
Nowhere. Passwords are generated locally in your browser and are never sent to or stored on our servers.
Is a PIN code as secure as a full password?
PIN codes are shorter and less secure than full passwords, so they should only be used where required, such as device unlock screens, not for online accounts.
