Allows you to obtain the UUID, both online and offline, of an entered
player name, or the name of the premium user associated with the UUID
provided.
This data is useful when testing techniques like UUID Spoofing
The green UUID in MCPTool is your premium user (in case the username entered has an official Minecraft account) and the red one is your client-generated offline uuid.
A UUID is a string of 36 characters, divided into 5 groups separated by hyphens, for example 123e4567-e89b-12d3-a456-426614174000. This ID is unique for each premium player and is permanently linked to your Minecraft Java Edition account through the Mojang/Microsoft authentication servers.
The UUID in Minecraft is generated differently depending on whether the player is premium or non-premium. For premium players, the UUID is created and managed by Mojang's official authentication servers, ensuring a globally unique and permanent identifier tied to the player's account, regardless of name changes. In contrast, non-premium players rely on a locally or server-generated UUID, based on their username.
