Customer Login -- Security Question
I am developing a FM database for a client who operates a moving and storage company. The file stores sensitive information including: name, phone number, email, and physical addresses. My client would like his customers to be able to log-in through web direct and access their record in order to obtain signatures, select options, etc.
Is there a way to do this that does not compromise the privacy and security of all the customers? We are currently hosting through filemakerhostingpros.com, but will obtain a copy of FM Server if that makes any difference.
