Passwords that actually protect you
Generate truly secure passwords. Understand entropy, crack times, and what makes a password strong. Test your own passwords, create passphrases — all locally, no tracking.

understanding password security
Entropy measures password strength in bits. Each additional bit doubles the time to crack. 80+ bits is considered secure against brute-force attacks.
Crack times shown assume: 1 billion guesses/second (professional GPU rig). Modern password managers recommend 16+ random characters or 4+ random words.
Avoid patterns like sequential numbers, keyboard patterns, dictionary words, or common substitutions (p@ssw0rd). The strongest passwords are random and unique.
