Authsignal + IdentityServer Example

Overview

Duende IdentityServer is an ASP.NET Core framework for building your own login server in compliance with OpenID Connect and OAuth 2.0 standards.

This example shows how to integrate IdentityServer with Authsignal:

1. Adding MFA to a traditional username & password login flow
2. Allowing passkey login as an secure and user-friendly alternative to username & password

Authsignal can be used to facilitate both MFA on login (step 1) and passwordless login (step 2).

For the full step-by-step guide check out our docs.

Running the Application

Prerequisites

• Authsignal Account
• .NET SDK
• Authsignal Dotnet SDK

Configuration

• Create an account at Authsignal and grab your Tenant ID, API host and API Key Secret.
• Add your AuthsignalSecret (API Key Secret) to both project's appsettings.json files:
  • src/IdentityServer/appsettings.json
  • src/WebClient/appsettings.json

Running the Application

1. Clone the repository

   git clone https://github.com/authsignal/identity-server-example.git
   cd identity-server-example
   

2. Start the IdentityServer (authentication server)

   cd src/IdentityServer
   dotnet run
   

   IdentityServer will run on https://localhost:5001

3. In a new terminal, start the WebClient (client application)

   cd src/WebClient
   dotnet run
   

   WebClient will run on https://localhost:5002

4. Open your browser and navigate to https://localhost:5002

   • You will be redirected to the IdentityServer login page
   • Log in with one of the test accounts:
     • Username: alice, Password: alice
     • Username: bob, Password: bob

5. After logging in, you'll be presented with MFA options if configured in your Authsignal account

Troubleshooting

• In development mode, the application is configured to accept untrusted SSL certificates
• If you encounter SSL certificate errors, you might need to trust the development certificates by running:

  dotnet dev-certs https --trust
