We paid for minecraft java edition and have no desire to use the online features.
Microsoft logs us out every damn time we close the software, which means my grade schoolers have my (now guessable) MS account password (and I scorch-earthed the account, because this is so dumb I won’t trust or use their crap moving forward).
Has anyone figured out how to pirate the binaries? I’d like to remove the yellow sticky note with the password from my monitor.
Use an alternate launcher, like MultiMC, and if you're not using the online features anyway, you can just "Launch in Offline Mode", which will just be unable to authenticate with legitimate servers.
You'd still need to log in to update the game (I think), but for your purposes it'd probably work pretty well.
