Password Combination Calculator

Your details

The number of characters in the password. Every extra character multiplies the search space by the pool size.

Adds 26 lowercase characters to the pool.
Adds 26 uppercase characters to the pool.
Adds 10 digit characters to the pool.
Adds 32 standard ASCII punctuation and symbol characters to the pool.
Estimated brute-force speed used to calculate the crack time. Online attacks are throttled by server rate limits; offline attacks against a leaked hash file are far faster.

71.5 bits of entropy - Moderate password space.

  • With a 12-character password from a pool of 62 characters, there are 3.23 sextillion possible passwords.
  • A moderate password space. Adding symbols or two more characters would push entropy above 80 bits, the threshold most security experts consider comfortable for general use.
  • At the selected attack speed, exhausting the full search space would take: 10 millennia.

Next stepTry increasing the password length by 2-4 characters, or enabling the symbol set, to reach a strong 80+ bit threshold.
