How It Works
We calculate "Entropy" based on length and character variety (uppercase, lowercase, numbers, symbols). Higher entropy means exponentially harder to crack.
Tips & Best Practices
- •Length beats complexity. A 15-char phrase is often stronger than an 8-char complex code.
- •Don't use common words or personal info.
- •Use a Password Manager to generate unique passwords for every site.
