Are you tired of struggling with custom authentication on Umbraco 13.3.2? Do you find yourself stuck in a never-ending loop of errors and frustrations? Fear not, dear developer, for we’ve got you covered. In this comprehensive guide, we’ll delve into the world of custom authentication using HttpContext.SignInAsync and explore the solutions to the pesky “User object not set” issue.
The Problem: “User object not set” Error
When implementing custom authentication on Umbraco 13.3.2, you may have encountered the following error:
Error: User object not setThis error occurs when the HttpContext.SignInAsync method is called without properly setting the User object. But fear not, we’ll show you how to overcome this hurdle and get your custom authentication up and running in no time.
Understanding Umbraco’s Authentication Pipeline
Before we dive into the solution, let’s take a brief look at Umbraco’s authentication pipeline. The pipeline consists of the following stages:
- Authentication Providers**: Umbraco uses authentication providers to authenticate users. These providers can be configured to use various authentication methods, such as username/password, OAuth, or custom implementations.
- Authentication Service**: The authentication service is responsible for validating the user’s credentials and returning an authentication result.
- SignInAsync Method**: The SignInAsync method is used to sign in the user and set the User object on the HttpContext.
Implementing Custom Authentication using HttpContext.SignInAsync
Now that we’ve covered the basics, let’s create a custom authentication implementation using HttpContext.SignInAsync. We’ll create a simple username/password authentication provider for demonstration purposes.
Step 1: Create a Custom Authentication Provider
Create a new class that inherits from Umbraco.Core.Security.IAuthenticationProvider. This class will contain the logic for authenticating users:
public class CustomAuthenticationProvider : IAuthenticationProvider
{
public bool Authenticate(string username, string password)
{
// TO DO: Implement custom authentication logic here
// For demonstration purposes, we'll assume a successful authentication
return true;
}
}
Step 2: Configure the Custom Authentication Provider
In the Startup.cs file, add the custom authentication provider to the authentication pipeline:
public void ConfigureServices(IServiceCollection services)
{
services.AddUmbraco(options =>
{
options.Authentication.Type = "Custom";
});
services.AddTransient();
}
Step 3: Implement the SignInAsync Method
Create a new class that inherits from Umbraco.Core.Security.SignInManager. This class will contain the implementation of the SignInAsync method:
public class CustomSignInManager : SignInManager
{
public override async Task SignInAsync(IUser user, bool isPersistent, string authenticationMethod)
{
await HttpContext.SignInAsync(user, isPersistent, authenticationMethod);
}
}
Step 4: Use the Custom SignIn Manager
In the Startup.cs file, replace the default SignInManager with the custom implementation:
public void ConfigureServices(IServiceCollection services)
{
services.AddTransient();
}
Solving the “User object not set” Error
So, why do we get the “User object not set” error when using HttpContext.SignInAsync? The reason lies in the fact that the User object on the HttpContext is not set before calling the SignInAsync method.
To solve this issue, we need to set the User object on the HttpContext before calling SignInAsync. We can do this by creating a new ClaimsPrincipal object and setting it on the HttpContext:
public override async Task SignInAsync(IUser user, bool isPersistent, string authenticationMethod)
{
var claims = new List<Claim>
{
new Claim(ClaimTypes.Name, user.Username),
new Claim(ClaimTypes.Email, user.Email)
};
var claimsPrincipal = new ClaimsPrincipal(new[] { new ClaimsIdentity(claims, authenticationMethod) });
HttpContext.User = claimsPrincipal;
await HttpContext.SignInAsync(claimsPrincipal, isPersistent, authenticationMethod);
}
By setting the User object on the HttpContext, we ensure that the SignInAsync method can properly sign in the user and set the authentication cookies.
Conclusion
Implementing custom authentication on Umbraco 13.3.2 can be a daunting task, but with the right guidance, you can overcome the challenges and create a robust and secure authentication system. By following this guide, you’ve learned how to use HttpContext.SignInAsync to implement custom authentication and solve the “User object not set” error.
Remember to always keep your custom authentication implementation secure and follow best practices for password storage and authentication. With custom authentication, you can unlock a world of possibilities and create a unique user experience for your Umbraco application.

Frequently Asked Question
Get answers to your burning questions about custom authentication on Umbraco 13.3.2 using HttpContext.SignInAsync.
Why is the User object not set after calling HttpContext.SignInAsync in Umbraco 13.3.2?
When you call HttpContext.SignInAsync, it only sets the authentication cookie, but it doesn’t automatically set the User object. This is because the User object is populated on the next request, not immediately after signing in. You can use RedirectToPage or RedirectToAction to force a redirect and then the User object will be set.
How do I manually set the User object after calling HttpContext.SignInAsync in Umbraco 13.3.2?
You can manually set the User object by using the UserManager to get the user and then setting the HttpContext.User property. For example: `var user = await _userManager.GetUserAsync(HttpContext.User); HttpContext.User = new ClaimsPrincipal(user);`. Keep in mind that this is not recommended as it can lead to unexpected behavior.
What is the correct way to use custom authentication with Umbraco 13.3.2 and HttpContext.SignInAsync?
The correct way is to use a custom authentication middleware that handles the sign-in process and sets the authentication cookie. Then, in your controller, use `await HttpContext.SignInAsync(userInfo)` to sign in the user. Make sure to redirect to another page or action after signing in to force the User object to be set.
Why does HttpContext.SignInAsync not work with Umbraco 13.3.2 out of the box?
Umbraco 13.3.2 uses a custom authentication pipeline that doesn’t integrate with the default ASP.NET Core authentication system. Therefore, HttpContext.SignInAsync doesn’t work out of the box and requires custom implementation to work with Umbraco’s authentication system.
Can I use HttpContext.SignInAsync with Umbraco 13.3.2 and still use Umbraco’s built-in membership system?
Yes, you can use HttpContext.SignInAsync with Umbraco 13.3.2 and still use Umbraco’s built-in membership system. However, you’ll need to implement a custom authentication middleware that integrates with both Umbraco’s membership system and ASP.NET Core’s authentication system.
I hope this helps! Let me know if you need anything else.
