What is Login Page in web application?

So, let's see the Login Page of the applications. If you get asked, you don't need to know. Basically you should think like this:

  • Login Page is the page where you can get authenticated before the access of the application.
     
  • Web Application is the interface to the main server and you can access the application through web browser. Before accessing the secured part of the application you must authenticate yourself with the website by providing your username and password. If you don't have username/password (account) on the website you should register with the website and create credentials(username/password) for yourself.
     
  • Login Form is the page where you can login to the application or the page where the system will display the information you are going to enter for the application. For example, you can login to website and access the secured dynamic content.
     
  • Insecure Login Page may lead to application security vulnerabilities in the web applications. So, you should properly secure your login page with the SSL and other security measures.

We all need to create some form on our site that is mandatory for the visitor to register and a new user to be able to access the website. For example, users would need to enter their email and provide their password to register if they are getting the login form from a login page.

By default such login forms are protected by the server. All we need to do is check if user's passphrases are correct before they can log in. If users' passphrases are not correct the user log out which could make the web application vulnerable because any wrong user can potentially use the login page as a login for other accounts.
