I want to have a link to a webpage, but keep it secure without using any membership authentication.
I will be sending an email out to people that will contain a code (ex: abc123).
When the user navigates to the page, before the page is displayed, I want them to be prompted to enter the code.
I'm using SQL and VS2013 C#. I'm thinking it would be a sql query on Page_Load code-behind to retreive/confirm code.
Any thoughts on how to do this?
