Passwords can be up to 15 alphanumeric characters.  They must contain a minimum of 5 characters.  They also may contain special characters.  There is not a way to require passwords to use numbers or characters.

FundWare has the Password Aging feature.  The Password Aging feature allows you to determine a specific number of calendar days that your users' passwords are valid.  When each user's password is nearing expiration, a warning will display offering the user the opportunity to change their password at that time.  This can be set up on the Home Page of System Administration.
