Use min digits in password to specify the minimum number of digits in a password. Valid values are:
0 through 16 – the minimum number of digits that must exist in a password.
-1 – the password cannot contain digits.
By default, this password complexity option is turned off and this check is not applied to passwords.
To set this option, enter:
sp_passwordpolicy 'set', 'min digits in password', number
For example, if you have set min digits in password to 4, you must have at least four digits in your password.
