As you may have gathered from the title I am selling my house. The website will only include photographs of the house and will be very minimal in content. To access the site I want users to be prompted with a login prompt which will require a bespoke password (available on request from our estate agent) which should change every 7 days or should expire 7 days after it has first been used. Is there a way to do this and if so would it require excessive SQL knowledge? Would this be extremely hard to design or can it be done easily? Many thanks.
