Name Bound
by Maxello
Name Bound runs only on the server, adds to Fabric on Minecraft 1.21.1, and gives every authenticated account a single character bearing its own name.
What it does
Each account is assigned a character name, such as John Smith for the account Maxello1, and that character is the identity the player keeps for one life. By default ordinary players see a surname shortened to an initial, so the same character shows as John S. When a player dies, the death message is published anonymously as Someone died, and the character is deleted, so a new character is created on the next join.
Only vanilla screens and packets are used, so an unmodified Minecraft 1.21.1 client is all a player needs to connect. Login bans, whitelists, permissions, selectors and other server administration keep using those real values. Vanilla networking still sends the real profile name, UUID and player-info data, so the mod is a masking interface rather than cryptographic anonymity. Players who are behind a proxy or a network observer can still recover usernames, which the author states plainly.
Key features
Character names
Each authenticated account receives one character name that stands in for its username in the game interface.
Surname display modes
The default mode shows a surname shortened to an initial, so ordinary players see names such as John S.
Anonymous deaths
A death is announced as Someone died, and the character is removed so that a new one is created after the next join.
Protocol-aware name replacement
Optional display-name components are replaced on the server, where an unmodified client normally renders them.
Team conflict handling
The existingTeamBehaviour setting decides what happens when an account is already on a non-Name Bound scoreboard team, with OVERRIDE as the default and SKIP leaving the team untouched.
