you'll notice we use extra characters in the passcode.

they are: ! @ # % & + ?

these characters can be misinterpreted as other letters or numbers by computer algorithms.

! could be mistaken for l or i or I depending on the font used.

@ could be a or o or c or C or O or 0.

# could be tt or tf or ft or ++.

& could be 8 or B or even D depending on text decoration.

+ could be t or f or even i or l or I depending text decoration.

% and ? are just there for plain ol' confusion.

also, we randomly choose a different font and text decoration like: italic, bold, underline, strike through.
