How To Set Login Page As Default In Asp Net

How To Articles

Setting the login page as the default page in an ASP.NET application is a common requirement for many web developers. In this article, I will guide you through the process of configuring the login page as the default page in an ASP.NET application. I will provide step-by-step instructions and also add some personal touches and commentary along the way.

Step 1: Creating the Login Page

The first step is to create the login page in your ASP.NET application. You can use ASP.NET Web Forms or ASP.NET MVC to create the login page, depending on your application’s architecture.

In my personal experience, I have found ASP.NET Web Forms to be a good choice for building login pages. It provides a rich set of controls like the Login control and CreateUserWizard control, which can simplify the login process.

Once you have created the login page, make sure it includes the necessary input fields for the user to enter their username and password. You can also include additional features like a “Remember Me” checkbox or a “Forgot Password” link to enhance the user experience.

Step 2: Configuring the Default Page

Now that we have our login page ready, let’s configure it as the default page for our ASP.NET application. To do this, we need to modify the web.config file of our application.

In your web.config file, locate the <system.web> section. Inside this section, you will find a <authentication> element. Within the <authentication> element, set the defaultUrl attribute to the URL of your login page. For example:

<authentication mode="Forms">
<forms loginUrl="~/Login.aspx" defaultUrl="~/Default.aspx" />

Make sure to replace ~/Login.aspx with the actual URL of your login page.

Step 3: Testing the Configuration

Now that we have configured our login page as the default page, let’s test it to ensure everything is working as expected.

Start your ASP.NET application and navigate to the root URL. You should be automatically redirected to the login page. If you are not redirected, make sure you have set the correct URL in the defaultUrl attribute in the web.config file.

On the login page, enter your username and password and click the “Login” button. If your credentials are correct, you should be redirected to the default page of your application. If not, make sure you have implemented the login functionality correctly.


In this article, we explored how to set the login page as the default page in an ASP.NET application. We started by creating the login page and then moved on to configuring it as the default page by modifying the web.config file. We also tested the configuration to ensure everything was working correctly.

Setting the login page as the default page can improve the user experience and make the authentication process seamless for your users. By following the steps outlined in this article, you should now be able to successfully set the login page as the default page in your ASP.NET application.
