Nedo.AspNet.Authentication.Auth0

Auth0 as the canonical token issuer (JWT-bearer pattern). Validates Auth0-issued JWTs and auto-maps Auth0's namespace-prefixed custom claims + RBAC permissions to ASP.NET Core's ClaimTypes.Role.

Install

dotnet add package Nedo.AspNet.Authentication.Auth0

Quickstart

using Nedo.AspNet.Authentication.Auth0;

builder.Services.AddAuth0(opts =>
{
    opts.Domain   = builder.Configuration["Auth0:Domain"]!;     // "my-tenant.auth0.com"
    opts.Audience = builder.Configuration["Auth0:Audience"]!;   // "https://api.example.com"
});

builder.Services.AddAuthorization();
builder.Services.AddHttpContextAccessor();
builder.Services.AddScoped<IAuthContext, AuthContext>();

var app = builder.Build();
app.UseAuthentication();
app.UseNedoAuthContext();
app.UseAuthorization();

app.MapGet("/admin", (IAuthContext auth) => auth.UserId)
   .RequireAuthorization(p => p.RequireRole("admin"));

Claims auto-mapping

Auth0 prefixes custom claims with a namespace URL (e.g. https://my-app.example.com/roles) to comply with OIDC. The defaults map the common shapes:

Auth0 claim Mapped to
https://{namespace}/roles: ["admin"] ClaimTypes.Role
permissions: ["read:reports", "write:reports"] (Auth0 RBAC) permission claims
email_verified left as-is
sub ClaimTypes.NameIdentifier

Configure your namespace via opts.RolesClaimNamespace = "https://my-app.example.com/roles"; if you use a non-default URL pattern.

Auth0 Action / Rule prerequisites

To get roles and permissions in the access token, configure them on the Auth0 side:

  • Roles — add an Action that copies event.user.app_metadata.roles (or your role source) onto event.accessToken under your namespace claim: 
    exports.onExecutePostLogin = async (event, api) => {
    const namespace = 'https://my-app.example.com/';
    api.accessToken.setCustomClaim(`${namespace}roles`, event.user.app_metadata?.roles ?? []);
};
  • Permissions — enable RBAC + "Add Permissions in the Access Token" on the API in the Auth0 dashboard.
