Unique Characters Rule

The Unique Characters rule rejects passwords that do not contain a minimum number of unique characters. For example, the password "aaaaaaaa" only contains one unique character (a), whereas "mypassword" contains nine unique characters (mypasword). Increasing the number of unique characters in a password increases password strength by avoiding repetitive sequences that are easily guessed. The Unique Characters rule is case sensitive, so "LoOpHole" contains seven unique characters (LoOpHole).

  • Enable the Unique characters button to enable the Unique Characters rule.
  • Must contain <_number_> or more unique characters – Select the minimum number of unique characters in the number drop-down list the passwords must contain.
