Minecraft on Switch will have you logging in with Xbox Live when cross-play update drops

This information comes from a PressFire interview with Mojang CEO Jonas Märtensson…

We’re tying everything together with Xbox Live. So you log in with Xbox Live …

Even on Switch?

Yes. (Laughs) That’s pretty unique as well! But everyone that’s in on this, all the platform holders, have been pretty pragmatic and understanding of that what we’re trying to do is create a good experience for the players. We needed a good system to connect everyone, and Xbox Live is a good system.
