How to add Authentication in Server-side Blazor | Blazor Tutorial 8

[@j_ason_rpg]

Gold to the first person to post a video showing how to properly generate authentication and authorization components using Blazor WITHOUT littering the project with Entity Framework, as so far, after looking far and wide, I have found no one.

[@Serjaru]

Good practice and respect for subscribers when posting sources code. This is for the future!

[@thibaudgalland1524]

Great video ! How would you handle the authentication process with an external WebApi and JWT token ?

[@RandomPerson-nh7yk]

Fantastic tutorial! Very helpful and works like a charm. One request though for a follow up video, I guess: could you possibly walk through how to add user roles to this process. I want to have various roles like Admin, Contributor, Readonly, etc. I know there are tables in the created database like Roles and UserRoles where such association is created, but how do I have those populated when users are created and then how do I retrieve this information to restrict access to various components accordingly? This would be very very helpful indeed!

[@onnuttig]

Thanks for the clear explanations, it was very easy to follow

[@iancarr3923]

Great thanks - fits it well with a current project.

[@whynotsquat8315]

I could not find your CLIENT-SIDE video. Also, no videos on WebAssembly Blazor at all? :(

[@morph4358]

What if we are using an external API to login using JWT and an external REST API to send and receive data, and we are using the Blazor app as if it was a Client which isn't directly connected to a database of its own? How would we then do this authentication/authorization?

[@MrBa143]

I know your comment is old, but for everyone else looking for a "custom" solution with or without your own database. You can create your own custom authentication state provider, and that will provide methods, in which you return AuthStates containing claims. You can then generate these claims yourself, based on your own data (A token you have received from your AuthProvider containing your claims / data etc)

[@KenzoArts]

Hello my friend, do you have a tutorial on CustomAuthentificationStateProvider ?

[@trongphan6197]

Thanks for the series. Can you do the login that using razor component for Blazor server?

[@shahab2025]

Thanks for Video, What is the name of IDE ?

[@DeathStarKitty]

at 12:55 when you add the logout link to _LoginPartial it should be a submit button inside a form so that LogOut.cshtml can handle the post. Otherwise it doesn't do anything but display a blank page.

[@naasthikan]

Can you please help me to do it i'm a beginner

[@naasthikan]

@@DMS20231 thanks for replying bro but it doesn't work

[@ej2649]

Yes. instead of using "LogOut", use " Logout"

[@graynoble4795]

Great video! Thank you!

[@joaquinlion]

Excuse me, are you using here the Authentication option when creating the project template from zero? how can i use this authentication option adding a postgreSql database for users data?

[@talkathiriify]

Great job Thank you very much.

[@bashirmanafikhi]

How can we set Identity layout to our blazor layout?

[@jozefkomara7065]

great tutorial

[@rainron2664]

Sir how about blazor server dealing with identity server?. 😊

[@3wsystems663]

not found...the .AddDefaultIdentity .. services.AddDefaultIdentity().AddEntityFrameworkStores();

[@MerrStudio]

How do I change the login form? I just want a login and a password and that's all. Also a simpler database table for logins.

[@Balgoriusis]

You must implement your own user class and usestore and give that to the identity Builder. That also means making all of the database calls for the userstore.

[@80-two]

Busta Rhymes?! Is that you?!

[@petemartinez3017]

I am a little confused because it seems like Identity Server 4 isn't free for Production.

[@nickchapsas]

This is ASP.NET Core Identity not Identity Server 4

[@petemartinez3017]

@@nickchapsas wasnt aware of that! Thanks for letting me know.

[@iraqjongen]

Where can I change the login view?

[@christianrazvan]

Now make the same video without using entity framework

[@mohammadmz1058]

Great video, but where is the source code

[@iteospace]

Try add scaffild identity pages for customizing and it broke your project

[@fahadmullaji]

If you use visual studio and select authentication support, when you create the project then all you showed comes out of the box

[@nickchapsas]

I am well aware of it. Rider has the exact same functionality. The point was to explain exactly what’s going on instead of blindly following it.

[@manoa98]

Wheres the Register and Login code page?

[@nickchapsas]

It’s within the aspens.identity package

[@filippomingo6784]

​@@nickchapsas yes but u dont show scaffolding, so my question is ho can i go to the Login's Url if is dosent exist the login page? The problem is that uo pass form the previous video to this one without showing some passages. I also pay the monthly bill but....

[@kourosh234]

wasn't it easier to scaffold the identity area?

[@nickchapsas]

It was you totally right but I would have to also explain what scaffolding is. I wanna keep my videos as self contained and as to the point as possible.

[@e.h.5680]

@@nickchapsas You hammered away at the keyboard for half an hour straight, to add something as straightforward as enabling authentication in a website. Either you are using the wrong way to do this or Blazor and its identity and authentication model is very broken.

[@wassollderscheiss33]

After watching until minute 1 I realized your example would employ those weirdo MS database tables for storing userdata. No sane person is interested in that. I would never litter my database with that.

[@sinan720]

Do you realize that you can customize it? If you're not smart enough to be able do that than thats your problem. Dont call people insane just because you dont know how asp net core identity works.

[@mohammadmz1058]

Just use mssql instead, like this: add nuget package: Microsoft.EntityFrameworkCore.SqlServer in program.cs add builder.Services.AddDbContext(options => options.UseSqlServer(builder.Configuration.GetConnectionString("DefaultConnection"))); and in in appsettings.json add "ConnectionStrings": { "DefaultConnection": "Server=localhost; Database=mydatabasename; Trusted_Connection=true; MultipleActiveResultSets=true; TrustServerCertificate=true;" },

Just another incomplete video. Where is the data(username password) in database against which the user will be validated. You did not show us that information.

[@nickchapsas]

Well that wasn't really polite but I'm going to reply anyway. Since we are using ASP.NET Core Identity, this is all managed automatically by .NET Core, and EF Core for us so we don't need to deal with it ourselves. This is why nobody is talking about it. Because nobody needs to. The framework is doing that for us.

[@resistnoevil622]

@@nickchapsas thanks for the reply. However, isn't there a way to add more fields(such as Country, City, Zipcode...) in the user-registration form generated by Blazor?

[@nickchapsas]

@@resistnoevil622 Yeah there is. You need to extend the IdentityUser class and add your own custom properties, then update the DbContext to be an IdentityDbContext and make sure that you create and run EF migrations and that's it.

[@resistnoevil622]

@@nickchapsas we can do this via ApplicationUser class, not IdentityDbContext. But can we customize the internal authentication logic, change field types etc? If yes, how?
