How can I play with lan in Minecraft?

So me and my brother would like to play Minecraft together on 2 PCs but unfortunately we only have one account.

then we tried to open a lan game but it didn't work.

do you have an idea how we can gamble together?

Download LogMeInHamachi on two PCs. Then someone hosts a server (you can easily download it from the Internet). Then join using the host's IP.

Create a test account and use it

OR

you both play offline

So I think it would be important to have an account. And gaming over lan works via the Hamachi program. Then you connect and someone starts a local game with the ip from hamachi
