Why You Need a Strong Password Generator

Human-created passwords are inherently predictable. Studies show that 81% of data breaches are caused by weak or reused passwords. Our password generator uses the Web Crypto API (the same cryptographic engine used by banks and governments) to create truly random passwords that are virtually impossible to crack.

How Strong Is a 16-Character Random Password?

A 16-character password using all character types has approximately 10^30 possible combinations. Even with the world's most powerful supercomputer testing 1 trillion passwords per second, it would take longer than the age of the universe to crack.

Password vs. Passphrase

While random character passwords are the most secure per-character, passphrases (like "correct-horse-battery-staple") are easier to remember. For maximum security without a password manager, use a 5+ word passphrase with numbers and symbols mixed in.

FAQ

Is this generator safe?

Yes. Passwords are generated entirely in your browser using the Web Crypto API. Nothing is sent to any server.

What password length should I use?

We recommend at least 16 characters for general use, and 20+ characters for high-security accounts like banking or cryptocurrency.

Should I include special characters?

Yes. Special characters dramatically increase the number of possible combinations, making brute-force attacks exponentially harder.
