# Speaking at Swetugg 2025

![Swetugg – Top Authentication Fails in ASP.NET Core (and How to Avoid Them)](https://tn-data.se/_astro/Swetugg_2025_Cropped.DACbXIbn_ZxH8LY.webp)

I’ll be speaking at [Swetugg](https://swetugg.se/) in Stockholm on February 4–5.

[Swetugg](https://swetugg.se) is a .NET conference with high-quality content at an affordable price. A team of volunteers runs it, and it is a good place for developers of all levels to learn and meet. The talks range from soft skills to advanced technical topics.

In my session [**Top Authentication Fails in ASP.NET Core (and How to Avoid Them)**](https://tn-data.se/talks/openid-connect/#top-authentication-fails-in-aspnet-core-and-how-to-avoid-them) I’ll share what I have learned from answering over 1,100 questions on Stack Overflow, many of them about authentication. I go through common mistakes developers make when they implement authentication in ASP.NET Core, and how to avoid them, with real-world examples, frequent misconfigurations and live demos.

If you want to learn more .NET or meet others in the community, join me at Swetugg. I’m looking forward to talking about authentication with other developers.

See you there!
