🔐 Do you really understand ASP .NET Core authentication... or do you just know that it works?
If you've ever copied an AddAuthentication() setup and hoped for the best, you're not alone.
In the latest Update Talk, @WesleyCabus joins Chris Woody Woodruff to explain what's actually happening behind ASP .NET Core's authentication middleware.
From authentication schemes and handlers to cookies, tokens, and headers, this conversation helps connect the dots behind the code. Because sooner or later, every developer runs into that authentication bug that can't be fixed with another copy-paste from StackOverflow.
🎥 Watch the conversation, then dive deeper with Wesley's full session, "ASP. NET Core Authentication Explained," available on the Update NOW Portal: now.updateconference.net

*Are you sure your access tokens are really secure?* by @WesleyCabus is a really great talk that exposes common validation mistakes that let attackers use forged tokens and explains how to prevent them.
