How to Generate a Strong Password

Use the slider to set your desired password length (16+ characters recommended). Toggle on the character types you want — uppercase, lowercase, numbers, and symbols. Click "Generate Password" and your new password appears instantly. Click "Copy" to copy it to your clipboard and paste it wherever you need it.

What Makes a Password Strong?

  • Length — longer passwords are exponentially harder to crack. 16+ characters is recommended. 20+ for high-security accounts.
  • Randomness — passwords based on real words, names, birthdays, or patterns are easy to guess. Truly random passwords are not.
  • Character variety — mixing uppercase, lowercase, numbers, and symbols dramatically increases the number of possible combinations.
  • Uniqueness — never reuse the same password across multiple sites. One breach shouldn't compromise all your accounts.

How Long Does It Take to Crack a Password?

Cracking time depends on password length and complexity. Here are rough estimates for a brute-force attack:

Password Security Tips

  • Use a password manager — tools like 1Password, Bitwarden, or the built-in managers in Chrome, Safari, and Firefox store unique passwords for every site.
  • Enable two-factor authentication (2FA) — even if someone gets your password, 2FA adds a second layer of protection.
  • Never share passwords — not by text, email, or chat. Legitimate services will never ask for your password.
  • Don't reuse passwords — if one site gets breached, unique passwords prevent a domino effect across your other accounts.
  • Change compromised passwords immediately — if a service reports a data breach, change your password for that site right away.
  • Avoid personal information — names, birthdays, pet names, and addresses are the first things attackers try.

Why Kids Should Learn About Password Security

Kids today have online accounts for school, gaming, email, and social media. Teaching password security early helps them protect their digital identity. At Hackingtons, students learn not just how to code — but how to think about security, privacy, and responsible technology use.

Frequently Asked Questions

Is this password generator safe?

Yes. Passwords are generated entirely in your browser using the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure randomness. No password is ever sent to a server or stored anywhere.

How long should my password be?

At least 12 characters for basic security. 16+ characters is recommended for most accounts. For high-security accounts (banking, primary email), use 20+ characters with all character types enabled.

Is this password generator free?

Yes — 100% free with no sign-up, no account, no ads, and no limits. Generate as many passwords as you need.

What makes a password strong?

A strong password is long (16+ characters), truly random (not based on words or personal info), and uses a mix of uppercase, lowercase, numbers, and symbols.

Do you store or see my passwords?

No. Everything runs in your browser. Passwords are generated using JavaScript and the Web Crypto API. Nothing is transmitted, logged, or stored.

Why shouldn't I reuse passwords?

If one site gets hacked and your password is leaked, attackers try that password on your other accounts. Unique passwords for each site means one breach doesn't compromise everything.

Should I use a password manager?

Yes. A password manager stores unique passwords for every site so you don't have to remember them. Popular options include 1Password, Bitwarden, and the built-in managers in Chrome, Safari, and Firefox.
