How to remove default ASP.NET Core Identity endpoints?

Question

Let's say I'd want to write my own Login, Logout endpoints and their Views

But for some reason I'm struggling hard with removing an existing endpoints

Whenever I remove things that probably are associated with those endpoints, then they recreate themselves and return their default Views.

Basically I'd want to remove as much as possible default endpoints/views of those generated from ASP.NET Core Identity

Any ideas on how can I acheive that?

Answer 1

You cannot use AddDefaultIdentity , since internally, this calls AddDefaultUI , which contains the Razor Pages "endpoints" you don't want. You'll need to use AddIdentity<TUser, TRole> or AddIdentityCore<TUser> instead.

Answer 2

I checked source code on ASPNET's Github and edited it a little bit

https://github.com/aspnet/Identity/blob/c7276ce2f76312ddd7fccad6e399da96b9f6fae1/src/UI/IdentityServiceCollectionUIExtensions.cs#L47

public static IdentityBuilder AddDefaultIdentity<TUser>(this IServiceCollection services, Action<IdentityOptions> configureOptions) where TUser : class
{
    services.AddAuthentication(o =>
    {
        o.DefaultScheme = IdentityConstants.ApplicationScheme;
        o.DefaultSignInScheme = IdentityConstants.ExternalScheme;
    })
    .AddIdentityCookies(o => { });

    return services.AddIdentityCore<TUser>(o =>
    {
        o.Stores.MaxLengthForKeys = 128;
        configureOptions?.Invoke(o);
    })
    .AddDefaultUI() // It'll be removed
    .AddDefaultTokenProviders();
}

Here's the code:

Extension method:

public static class IServiceCollectionExtensions
{
    public static IdentityBuilder AddCustomDefaultIdentity<TUser>(this IServiceCollection services, Action<IdentityOptions> configureOptions) where TUser : class
    {
        services.AddAuthentication(o =>
        {
            o.DefaultScheme = IdentityConstants.ApplicationScheme;
            o.DefaultSignInScheme = IdentityConstants.ExternalScheme;
        })
        .AddIdentityCookies(o => { });

        return services.AddIdentityCore<TUser>(o =>
        {
            o.Stores.MaxLengthForKeys = 128;
            configureOptions?.Invoke(o);
        })
        .AddDefaultTokenProviders();
    }
}

Startup.cs

services.AddCustomDefaultIdentity<User>
(
    o => { /* options e.g */ o.Password.RequireDigit = true;}
)
.AddSignInManager()
.AddEntityFrameworkStores<Context>();

services.ConfigureApplicationCookie(options =>
{
    options.AccessDeniedPath = "some_value";
    options.Cookie.Name = "some_value";
    options.Cookie.HttpOnly = some_value;
    options.ExpireTimeSpan = TimeSpan.FromMinutes(some_value);
    options.LoginPath = "some_value";
    options.LogoutPath = "some_value";
    options.ReturnUrlParameter = CookieAuthenticationDefaults.some_value;
    options.SlidingExpiration = some_value;
});
