In my previous article, I wrote about how to authenticate by creating new user accounts. Now what if, anyone doesn’t want to add another pair of user id password to his memory and want to use the existing ones which he/she is using very frequently in his/her day-to-day life. Well, here comes the external providers in the picture. In this article, I won’t be covering the basics on how to create a website from scratch as it is already covered in an earlier article. So, let’s quickly jump on to the login screen and on right hand side, you will see the text as ‘Use another service to log in.’ . It  also provides a hyperlink, which will guide us on how to setup the authentication using external providers. What are external providers? There is a huge list of authentication providers. The most common one’s are Twitter, Facebook, Google and Microsoft. This list is not restricted till here as it can be any other custom provider. Throughout this article, I’ll be driving you to set

Today I’m so happy and excited to share with you all that I’ve received the Most valuable Professional (MVP) award from C# Corner for the second time. Last week, I received an email that I’ve been awarded this esteemed award for my community contributions.

Recently I met one of my readers and he asked me what is authentication and why is it required in very simple terms. So, here is the post. What is Authentication? To understand the fundamentals of authentication, let's begin by taking an easy example. You are working on some file and now you want to share that file to a person named XYZ over OneDrive. So, the purpose of authentication in this case is to make sure that only XYZ can access that document. How to achieve it? It can be achieved by setting up the authentication system and this system will tell who all can access this file based on some predefined rules. In our case, the rule is simple - none except XYZ should be able to access the file. How verification happens? Entire verification activity solely depends on our authentication system. When I'm saying authentication system, it means it is nothing but a piece of software written by someone. Now how will this piece of software validate the incoming us

In this article, I’m going to write bit about security aspects in ASP.Net Core 2.0. Whenever you create a new ASP.NET Core application, you must notice that there is an option on dialog with a button captioned as Change Authentication and once you click on that, you will land upon a dialog having below 4 options as shown below:    I’ll discuss about each of these options in detail but as of now, to get started, let’s take a high-level idea about these No Authentication – which means application is completely anonymous and open for everyone to access it. Individual User Accounts – it uses local database for storing the information related to user. Work or School Accounts – it means application will work with Office365, Active Directory, support for cloud, etc.. Windows Authentication – For internet application and uses IIS capabilities to know who has logged in. Here I’ll be choosing my option as ‘ Individual User Accounts ’ which is very easy, simplest as well

This time rather than jumping directly into the topic, let's have a look at the Login form code which you must have definitely seen while working on MVC application. What do you think about the above code snippet? Indeed, it works alright, but there are few problems with this. But the major problem is its a bit messy and difficult to read due to excessive use of @. So, now we have understood the problem, what is the solution? Here comes the Tag Helpers for our rescue. Let's quickly have a look at the code generated by the ASP.NET Core framework for the same functionality: The above code looks much cleaner. Isn’t it? If it looks interesting to you, we should learn more about it. What are Tag Helpers Tag Helpers are classes written in C# but are attached to HTML elements in order to run server-side code from Razor view. In other words, view created in HTML has its presentation logic defined in C#, which is ultimately executed on the w
