Security Best Practices
Length Matters
A longer password is significantly harder to crack. Aim for at least 12-16 characters for critical accounts.
Mix it Up
Combining letters, numbers, and symbols creates exponential complexity for brute-force attacks.
Unique is Key
Never reuse passwords across different sites. If one account is compromised, your others remain safe.
How it works
This generator uses the Web Crypto API, specifically window.crypto.getRandomValues(). This provides "cryptographically strong" random numbers, unlike standard Math.random(), ensuring your passwords are truly unpredictable. Everything happens in your browser—no data is sent to any server.
