Password Generator
Generate cryptographically secure random passwords in one click. Choose your desired length and character set — uppercase letters, lowercase letters, numbers, and symbols — and copy the result to your clipboard instantly. Passwords are generated entirely in your browser and never transmitted anywhere.
How to use the Password Generator
Set the password length using the slider (8–64 characters), toggle the character types you want to include, and click Generate. Click the copy icon to copy the password to your clipboard without having to select it manually.
How secure passwords are generated
The generator uses the browser's built-in crypto.getRandomValues() API, which draws from the operating system's cryptographically secure pseudo-random number generator (CSPRNG). This is the same source used by cryptographic libraries. The character pool is assembled from your selected options, and each position in the password is filled by drawing a random index into that pool. Because each character is chosen independently from a uniform distribution, guessing a 20-character password with all character types would require testing roughly 9520 ≈ 1039 combinations.
