How to Find Your Minecraft Java Username for ENDOS SMP
When signing up for ENDOS SMP, you must enter the player's Minecraft Java Edition username. This is one of the most common signup mistakes, especially for families who use Xbox, Bedrock, or Microsoft accounts.
Why the Java username matters
ENDOS SMP is a Minecraft Java server. The whitelist uses the player's Java profile name, not an Xbox gamertag, email address, Microsoft account name, or Bedrock display name.
