No, case sensitive only means that the upper or lowercase characters will be remembered as such. For example, if your psword contains an uppercase letter, it will not be accepted if that letter is entered in lowercase. For something that is not case sensitive, this will not matter. In a case sensitive scenario, if your psword is Killjoy1, when typed killjoy1 it will not be accepted.
