Let's say, for example, I want to create a specialized calendar application for consumers. Once I'm done creating this web application, I now want to make this web application customer-facing where each customer can:
- Create his own unique login / password
- See ONLY his data that he enters
In theory, I would like to have hundreds -- if not thousands -- of clients to use this web application, each with his own unique login credentials and data only he can see when he logs in.
Million-Dollar Question: Can I create the above...? If so, would it cost anything extra (beyond my monthly Starter or Pro subscription) to accomplish this...?
