How It Works
Our password generator uses advanced cryptographic techniques to create secure, unpredictable passwords that protect your digital identity.
Cryptographically Secure Randomness
Unlike simple random functions, we use the browser's built-in crypto.getRandomValues() API, which provides cryptographically strong random values that are:
- Unpredictable: Even knowing previous passwords won't help predict future ones
- High-entropy: Maximizes randomness to resist brute force attacks
- Non-deterministic: Generated using hardware sources of randomness
// Cryptographically secure random selection
const randomIndex = Math.floor(
crypto.getRandomValues(new Uint32Array(1))[0]
/ (0xffffffff + 1) * chars.length
);
password += chars.charAt(randomIndex);Character Set Selection
You control exactly what goes into your password by selecting which character types to include:
- Alphanumeric: A-Z, a-z, 0-9
- Numbers only: 0-9
- Alphabets only: A-Z, a-z
- Special characters: !@#$%^&*()_+-=[]{}|;:',.<>?/`~
This flexibility allows you to create passwords that meet specific requirements for different services.
Balanced Distribution
Our algorithm ensures that your password includes at least one character from each selected type. This prevents the random generation from creating a password that's missing a required character type.
After generating the initial random password, we shuffle the positions and strategically insert characters from each selected type, ensuring a balanced but still random distribution.
