# How to Implement form Authentication in MVC?

Step 1- Set the form authentication mode equals to form

Step 2-In web.config add following code

Inside system.web

```
    <authentication mode="Forms">      <forms loginUrl="~/Home/SignIn" timeout="2880"/>    </authentication>
```

Step 3-In this step we need to controller for checking authentication. Here we check that user is authorize or not.

In home controller add following code

```
        [Authorize]       
public ActionResult About()       
{            return View();//This
view is viewed by authenticated user only       
}        [HttpPost]       
public ActionResult SignIn(Login Model)       
{             if
((Request.Form["txtUserName"] == "Manish")
&&        
(Request.Form["txtPassword"] == "Mindstick"))            {                FormsAuthentication.SetAuthCookie("Manish", true);                return View("About");            }            else            {                return View("Index");            }
```
