Your Password must be at least 8 characters long.
A strong password is not required, but highly recommended.
To increase password strength, use at least 1 number,
capitalized letter, and special character.
The "Strength" box is just a measure of password strength and is only for your convenience.
Strong passwords contain at least 3 of the 4:
lowercase letters
UPPERCASE letters
Numbers (1,2,3,etc.)
Symbols ($,(,),|,!,etc.)
