Implementing Level of Identification (LoI) with ASP.NET Core Identity and Duende
This article explores how to implement Level of Identification (LOI) in an ASP.NET Core application. The solution uses Duende IdentityServer as the OpenID Connect provider and ASP.NET Core Identity for user management. Identity verification is performed using the Swiyu Public Beta infrastructure. Any OpenID Connect client can consume the loi claim together with the loa […]
Implementing Level of Authentication (LoA) with ASP.NET Core Identity and Duende
This post shows how to implement an application which requires a user to authenticate using passkeys. The identity provider returns three claims to prove the authentication level (loa), the identity level, (loi) and the amr claim showing the used authentication method. Code: https://github.com/swiss-ssi-group/swiyu-passkeys-idp-loi-loa Blogs in this series: The amr claim and the loa claim returns […]
Implement forgot your password using swiyu, ASP.NET Core Identity and Aspire
This post show to implement a “Forgot your password” flow using the Swiss Digital identity and trust infrastructure, (swiyu) in an ASP.NET Core web application using ASP.NET Core Identity and Duende IdentityServer. The generic containers from swiyu are used to integrate the Swiss E-ID and the OpenID for Verifiable Presentations standards. .NET Aspire is used […]
Implement MFA using swiyu, the Swiss E-ID with Duende IdentityServer, ASP.NET Core Identity and .NET Aspire
The post shows how to use the Swiss Digital identity and trust infrastructure, (swiyu) as an MFA method in an ASP.NET Core web application using ASP.NET Core Identity and Duende IdentityServer. The generic containers from swiyu are used to integrate the Swiss E-ID and the OpenID for Verifiable Presentations standards. Code: https://github.com/swiss-ssi-group/swiyu-idp-mfa-aspire-aspnetcore Blogs in this […]
Use swiyu, the Swiss E-ID to authenticate users with Duende and .NET Aspire
This post shows how to authenticate users using Duende IdentityServer and ASP.NET Core Identity which verifies identities (verifiable digital credentials) using the Swiss Digital identity and trust infrastructure (swiyu). The swiyu infrastructure is implemented using the provided generic containers which implement the OpenID for Verifiable Presentations standards as well as many other standards for implementing […]
Implement a secure MCP OAuth desktop client using OAuth and Entra ID
The article demonstrates how to implement a secure MCP OAuth desktop client using Microsoft Entra ID. The MCP server is built with ASP.NET Core and secured using Microsoft Entra ID. The MCP client is a .NET console application that must acquire an OAuth access token to interact with the MCP server. Code: https://github.com/damienbod/McpSecurity Setup A […]
Implement a secure MCP server using OAuth and Entra ID
The article shows how to implement a secure model context protocol (MCP) server using OAuth and Entra ID. The MCP server is implemented using ASP.NET Core and uses Microsoft Entra ID to secure the API. An ASP.NET Core application using Azure OpenAI and semantic kernel is used to implement the MCP client for the agent […]
Handling OpenID Connect error events in ASP.NET Core
ASP.NET Core provides great extension points for handling OpenID Connect error events. This blog looks at implementing error handling in an ASP.NET Core application implemented using ASP.NET Core Identity. Code: https://github.com/damienbod/IdentityExternalErrorHandling Setup The application uses OpenID Connect to implement the authentication of the user identities. This implements a standard OpenID Connect flow and uses Microsoft […]
Implement client assertions with client credentials flow using OAuth DPoP
This blog looks at implementing client assertions for the client credentials flow using OAuth 2.0 Demonstration of Proof-of-Possession (DPoP). The client credentials flow is an OAuth 2.0 authorization grant type used for machine-to-machine authentication. DPoP further strengthens the security by ensuring that the client possesses a specific key at the time of the request, forcing […]
ASP.NET Core delegated Microsoft OBO access token management (Entra only)
This blog shows how to implement a delegated Microsoft On-Behalf-Of flow in ASP.NET Core, and has a focus on access token management. The solution uses Microsoft.Identity.Web to implement the different flows and it really simple to implement, when you know how to use the Nuget package and use the correct Microsoft documentation. The application can […]
