Confusing between characters within the password string is annoyong. The solution to avoid cofusion between I (cap letter or small letter I), small letter L, 1 (the digit), 0 (zero) & O (cap or small letter), can be done by adding a feature to enable changing the font of the password display. Or, just put an appropriate font that differentiates between these characters.
