Why Use a Password Generator?

Humans are notoriously bad at creating random passwords. We tend to use dictionary words, predictable patterns, and personal information — all of which make passwords easy to crack. A password generator creates truly random strings that resist brute-force and dictionary attacks.

How to Use This Tool

  1. Set your desired password length (8–128 characters)
  2. Choose which character types to include
  3. Click “Generate” to create a new password
  4. Copy the password to your clipboard

  • Update passwords immediately if a service reports a breach

Need a password manager? 1Password and Bitwarden are excellent choices trusted by millions of developers.

Frequently Asked Questions

How secure are the generated passwords?

Passwords are generated using the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. This is the same source of randomness used by security-critical applications.

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. Longer passwords are exponentially harder to crack.

Are the passwords stored anywhere?

No. Passwords are generated entirely in your browser and are never sent to any server. Once you leave the page, the passwords exist only if you saved them.

How long should my password be?

We recommend at least 16 characters for important accounts. Each additional character multiplies the number of possible combinations, making brute-force attacks exponentially harder.

Should I use a password manager?

Absolutely. Password managers like 1Password or Bitwarden store all your passwords securely so you only need to remember one master password. They can also generate strong passwords for you.
