Why You Need a Strong Password

Password-related cybercrime affects users worldwide every year. The most common attack vectors are:

  • Brute force attacks - billions of guesses per second by automated bots
  • Credential stuffing - using leaked passwords across multiple sites
  • Dictionary attacks - common words and patterns are tried first

A 16-character random password with mixed character types takes trillions of years to brute force, even with the most powerful computers. By contrast, "password123" can be cracked in under 1 second.

Our generator uses the Web Crypto API - the same cryptographic standard used by banks and governments - to ensure true randomness. The password is generated entirely in your browser; nothing is sent to any server.

Password Safety Tips Before You Create a New Login

Strong passwords should be long, unique, and hard to guess. A password that is reused across multiple accounts can become risky if one website has a data breach, so generate a fresh password for every important account.

For banking, email, hosting, cloud storage, and admin panels, use a password manager to store generated passwords securely. A longer password with mixed characters is usually more useful than a short password with only small substitutions.

Best use cases

  • Create passwords for hosting accounts
  • Generate admin panel credentials
  • Protect email and cloud storage accounts
  • Make temporary secure passwords for client handoff

Pro tips

  • Use at least 16 characters for important accounts
  • Never reuse passwords
  • Enable two-factor authentication
  • Store passwords in a trusted password manager

Frequently Asked Questions

How secure are these passwords?

We use Web Crypto API (crypto.getRandomValues) for cryptographically secure random numbers. A 16-char mixed password takes trillions of years to brute-force.

Is the password sent anywhere?

No. Generated entirely in your browser. Never transmitted, logged, or stored on any server.

What length is recommended?

For most accounts, 16 chars mixed is excellent. For banking/email, use 20+ characters.
