FAQ
UUID lookup FAQ
What is a UUID?
Every Minecraft account has a fixed ID called a UUID. Names can change; the UUID never does, so whitelists and ops use it.
Why are offline-mode UUIDs different?
Offline servers do not ask Mojang, so they make the ID from the name. That is why changing online-mode makes players lose their items.
Is there an easier way?
On a running server, type whitelist add Name or op Name in the console. The files are handy when you set up a new server.
Is this tool free?
Yes. Free, no account, no limits for normal use. We host Minecraft servers and made these tools to help server owners.
