  • This calculator assumes the password is randomly generated (Example: AqdPHw=x7*Mz7LPp).
  • Reusing a password gives you a weak score because password reuse increases your chances of being affected by credential stuffing attacks. Every account needs to have its own random password that you never reuse; a password manager makes this easy.
  • The answers above are how long it would take to go through every possibility. You can safely divide the answers above in half to give the attacker a 50/50 shot of finding the password in the first half of guesses.
  • Bitcoin mining is not set up to crack passwords and is only used as an over-the-top example.
