Clear, practical explainers about passwords, entropy and account security.
What Makes a Password Strong
Length, randomness and uniqueness — not clever substitutions — are what actually make a password hard to crack. Here's how each one works.
Password Entropy Explained
Entropy is the one number that objectively measures password strength. Learn the formula, what the bits mean and how to read a crack-time estimate.
Passphrases vs Passwords: Which to Use
Random character strings and multi-word passphrases can be equally strong. The difference is where you use them and whether you have to remember them.
