Why Password Strength Matters
Entropy Explained
Entropy measures the unpredictability of a password in bits. Higher entropy means a password is harder for hackers to crack using brute-force methods. A secure password should ideally have at least 80 bits of entropy.
Secure Generation
This tool uses the crypto.getRandomValues() API, which provides cryptographically strong random numbers. Unlike Math.random(), this ensures your passwords are truly unpredictable.
