Good day, IT Source Coders! For this simple tutorial, you can learn the step-by-step and easy process of How To Create a Login Page In ASP.net MVC with Database.

A login page is a web page or website entry page that requires user identification and authentication, which is often accomplished by providing a username and password combination.

Logins might give you access to the full site or just a section of it.

Logging in allows the website to track the user’s activity and habits in addition to providing site access.

The user can log off a webpage or site manually, or it can happen automatically when specified criteria (such as closing the page, turning off the computer, or waiting a long period) are met.

SQL login is specific for the database server, and SQL Server database user is set for individual SQL Server Database if the SQL Server login is the Windows system account.
SQL Server login account differs from a Database user in that it is the login user for a SQL Server database. If you have multiple databases, each database user has their own SQL Server login. At the same time, one or a few login users are restricted to a single database user.

So far, we’ve learned that SQL Server login is linked to the database user and that the two are distinct.

To connect to SQL Server, you’ll need an SQL Server login, and you’ll need a database user to access a specific database.

We could only log into SQL Server and access a certain database if we logged in as both SQL Server and database user at the same time.

In this 2022 ASP.NET tutorial, We will learn How To Create a Login Page In ASP.NET MVC with a Database.

A programmer can develop two types of login forms: one that is static and the other that is dynamic.

The username and password in a static login form are fixed and predefined by the programmer, however in a dynamic login form, the username and password match the database username and password, and multiple users can log in with this dynamic login form.

Create a database table for username and password before creating a dynamic login form in asp.net.

We’ve made a table called “LoginMst” that has three columns: ID, Username, and Password.

We first check if the username and password textboxes are blank in this asp.net login form example, then show the error message “Please input username” for the username textbox and “Please enter password” for the password textbox using the required field validator control in asp.net.

If the textbox is not empty, compare the username and password to database fields; if they match, display a success message such as “Welcome to System,” if they don’t, display an error message such as “Invalid username and password.”
