Writing a registration system is a lot of work. You have to write code that validates email addresses, sends confirmation emails, provides forgotten password functionality, stores passwords securely, validates input forms and a lot more. Even when you do all of this, users will still be reluctant to register as it involves a lot of effort on their part as well.
In this tutorial, we will make a very simple registration system that doesn’t require or store passwords at all! The result will be easy to modify and embed into an existing PHP website. Read on to find out how it works.
