Password Strength Algorithm:

Password Length:
5 Points: Less than 4 characters
10 Points: 5 to 7 characters
25 Points: 8 or more

Letters:
0 Points: No letters
10 Points: Letters are all lower case
20 Points: Letters are upper case and lower case

Numbers:
0 Points: No numbers
10 Points: 1 number
20 Points: 3 or more numbers

Characters:
0 Points: No characters
10 Points: 1 character
25 Points: More than 1 character

Bonus:
2 Points: Letters and numbers
3 Points: Letters, numbers, and characters
5 Points: Mixed case letters, numbers, and characters

Password Text Range:

>= 90: Very Secure
>= 80: Secure
>= 70: Very Strong
>= 60: Strong
>= 50: Average
>= 25: Weak
>= 0: Very Weak
