2. Login!

You can now run mc-authn to login! After logging in, it will create a text file ~/.config/mc-auth/mc-token.txt containing your minecraft token.

In your start script for minecraft, add the --accessToken argument to the java line used to start minecraft:

mc-authn

export name=$(< ~/.config/mc-auth/mc-name.txt)
export uuid=$(< ~/.config/mc-auth/mc-uuid.txt)
export auth=$(< ~/.config/mc-auth/mc-token.txt)

java ... net.minecraft.client.main.Main ... \
    --accessToken ${auth} \
    --uuid ${uuid} \
    --username ${name}

3. Start Minecraft!

You can now start minecraft!
