What is Forms Authentication in ASP.NET and how does it work?

Question

ICSM Computer · Answer

Forms Authentication in ASP.NET is a way to authenticate users by having them log in through a web form. Instead of using Windows authentication, users enter their credentials on a login page. When they successfully log in, ASP.NET issues an authentication ticket, usually stored in a cookie, which identifies the user on subsequent requests. How Forms Authentication Works: The user tries to access a page or resource that requires authentication.If the user is not authenticated, ASP.NET automatically redirects them to a configured login page.The user submits their username and password on the login page.The application validates the credentials (often by checking a database).If validation succeeds, ASP.NET creates an authentication ticket and places it in a cookie sent to the user's browser.For all future requests, the browser sends this cookie back to the server, and ASP.NET uses it to identify and authenticate the user. Configuration example in web.config: The loginUrl specifies the page where users enter their credentials.The &lt;deny users="?"&gt; means anonymous users (not logged in) are denied access to the protected resources. Creating the authentication ticket in code: Logging out: Summary Users log in through a form.A cookie holds an encrypted ticket identifying the user.ASP.NET uses this ticket to authenticate requests.Works well for web apps requiring simple login functionality.
