with a minimum length of seven characters that contains at least one non-alphanumeric character.
It displays an appropriate error message below the control, shown in Figure 16-15. Note that numbers are not considered non-alphanumeric characters, so you need to make sure your password contains at least one character like # or $ or *. For example, Pa55word is not a valid password, but Pass##Word will be accepted. Also note that the password is case sensitive.
