Your Passwords

A password generator creates random, hard-to-guess passwords using cryptographic randomness. It eliminates the human tendency to pick predictable patterns — birthdays, pet names, "password123" — that attackers exploit first.

According to Verizon's 2024 Data Breach Investigations Report, 81% of hacking-related breaches involve stolen or weak passwords. The average person has over 100 online accounts (NordPass, 2023), making it practically impossible to create and remember unique strong passwords without a tool.

This generator uses the Web Crypto API (crypto.getRandomValues), the same cryptographic random number generator used by banking and security applications. Unlike Math.random(), which is predictable, crypto.getRandomValues provides true cryptographic randomness suitable for security-sensitive use.

The strength of a password is measured in entropy — the number of possible combinations an attacker would need to try. A 12-character password using all character types has roughly 79 bits of entropy, meaning 2^79 possible combinations. At one trillion guesses per second, that would take over 19,000 years to crack by brute force.

Every password generated here stays in your browser. Nothing is transmitted, stored, or logged. You can verify this by checking your browser's network tab — no requests are made when generating passwords.

How to Use This Generator

  1. Set your length: Use the slider to choose password length. 16 characters is a good default for most accounts.
  2. Choose character types: Toggle uppercase, lowercase, numbers, and symbols. More character types increase strength.
  3. Generate: Passwords generate automatically as you change settings. Click "Regenerate" for new ones.
  4. Check the strength meter: The visual indicator shows estimated crack time based on current computing power.
  5. Copy and store: Click the copy button next to any password, then paste it into your password manager or account settings.

Pro Tips

  • Use 16+ characters: Every extra character multiplies the difficulty exponentially. Going from 12 to 16 characters makes brute-forcing roughly 65,000 times harder.
  • Enable all character types: Using uppercase, lowercase, numbers, AND symbols maximizes entropy per character from 26 possibilities to 95.
  • Use a password manager: Generate unique passwords for every account and store them in a password manager like Bitwarden, 1Password, or KeePass.
  • Enable 2FA: Even the strongest password can be phished. Two-factor authentication adds a second layer that stops most attacks.
  • Never reuse passwords: If one service is breached, attackers will try that password on every other service you use. Unique passwords contain the damage.

Frequently Asked Questions

What makes a password strong?
A strong password is at least 12 characters long and includes a mix of uppercase letters, lowercase letters, numbers, and special characters. Length is the single most important factor — each additional character exponentially increases the time needed to crack it. A 16-character random password would take billions of years to brute-force with current technology.
Is this password generator safe to use?
Yes. This generator runs entirely in your browser using the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. No passwords are sent to any server, stored, or logged. The code is visible in your browser's developer tools if you want to verify.
How long should my password be?
NIST (National Institute of Standards and Technology) recommends a minimum of 8 characters, but security experts recommend 14-16 characters or more. For high-security accounts like banking or email, use 20+ characters. Longer passwords are exponentially harder to crack.
Should I use a different password for every account?
Absolutely. Credential stuffing attacks use leaked passwords from one site to try logging into others. If you reuse passwords, a single breach compromises all your accounts. Use a password manager to store unique passwords for every service.
Are passphrases better than random passwords?
Passphrases (like 'correct horse battery staple') are easier to remember and can be very secure if long enough (4+ random words). However, truly random passwords of the same length have higher entropy. For accounts protected by a password manager, random passwords are ideal since you don't need to memorize them.
How often should I change my passwords?
NIST's 2024 guidelines no longer recommend routine password changes. Instead, change passwords only when you suspect a breach or compromise. Frequent forced changes lead to weaker passwords because users make minimal modifications. Focus on unique, strong passwords and enable two-factor authentication.
