Cross-Device Identity Verification via Entra Verified ID in a Multi-Agent System

TL;DR A multi-agent system (.NET 9 + Anthropic Claude) that embeds Entra Verified ID directly into the conversation. A QR code appears in chat, the user scans it with their wallet (Microsoft Authenticator), and the agent receives cryptographic proof of identity before it acts. Five layers of security enforcement — from probabilistic prompts to deterministic hooks — ensure identity verification cannot be skipped. The Problem: AI Agents Acting Without Proof AI agents are increasingly asked to perform sensitive operations — unlocking accounts, resetting credentials, approving transactions. But how does an agent know who it’s talking to? A username typed into chat is not identity. A “yes, that’s me” confirmation is not proof. ...

Build faster with AI Assist!

TL;DR I’m using AI tools to generate code for my projects. Here I want to show you GitHub Copilot, Bolt, Aider, and GitHub Copilot Workspace. I’m happy with the results from Aider with the Claude AI model, and Bolt is perfect for generating a nice starting point for my front-end projects. GitHub Copilot is ideal for small code snippets. Introduction Happy New Year! This post will be my summary and notes on how I use AI daily as a software developer, or maybe it will be better to name it proof of concept or demo developer ;) I will focus only on the tools that help me write/generate the code. ...
