ASP.NET SimpleIdentity

A simple ASP.NET Core authentication and identity provider, ideal for smaller websites. Valid users are specified in a simple configuration file rather than a database.

Bug reports and feature requests are welcome!


If you are creating a brand new ASP.NET Core web application, ensure you select "No Authentication" when creating it.

Install NuGet package:

Install-Package Daniel15.SimpleIdentity

Create configuration. SimpleIdentity uses the standard ASP.NET configuration library. Running Daniel15.SimpleIdentity.Setup will allow you to enter a email address and password, and output the required config section. An example using as the email address and password as the password:

    "Auth": {
        "Users": {
            "USER@EXAMPLE.COM": {
                "Email": "",
                "NormalizedUserName": "USER@EXAMPLE.COM",
                "PasswordHash": "AQAAAAEAACcQAAAAEJOYL0MGZ5CNnERvqzI2Wl9eJLXMsuchKP1EIWGQneZ1GuNCjheC4pD1AWgVy+decQ=="

Place this in any config file (for example, config.json). In a production scenario, you will want to store this in a separate config file that's not checked in to source control.

Configure SimpleIdentity in Startup.cs:

public void ConfigureServices(IServiceCollection services)
    // Add Identity services to the services container.
    services.AddIdentity<SimpleIdentityUser, SimpleIdentityRole>()

Enable identity services by adding this before app.UseMvc:

// Add cookie-based authentication to the request pipeline.

Create login form. Some example files are included, based off the regular ASP.NET authentication:

Hit /Account/Login and it should work :)

For a full example, see the included sample project.
