Okay that’s what I was guessing but I wanted to double check. That’s cool though!

Does authlib-injector allow you to spoof a mojang account or does it just make alternative authentication easier?

Most launchers I’ve used allow you to launch unverified or “offline” instances which I believe should be the same as what the cracked instances would do as well. The main downside is that you can’t join any public servers that don’t have Mojang authentication on (just like the cracked versions).
