Fuzzy password matching checks for multiple variants of the password, including case insensitivity and common substitutions such as leetspeak (o for 0, i for 1, e for 3, a for 4, etc.) and reversing the order of characters.

For example, the password 'G30rg13' would be evaluated as written, but also evaluated as 'georgie' and 'eigroeg'. 

When enabled, Fuzzy Matching is also applied to entries in the Custom Dictionary
