Modifying the minecraft:brand String Sent to Servers

How the Brand Handshake Operates

Whenever you join a multiplayer Minecraft server, your game client sends an internal identifier known as the minecraft:brand string during the initial login phase. By default, vanilla or standard mod loaders transmit fixed brand text. Custom Client Brand Mod replaces this automatic transmission with a custom string of your choice.

Updating the Login Brand

To ensure the server receives your customized brand string upon connection:

1. Open Mod Menu from the main menu or the in-game pause screen.

2. Select Custom Client Brand Mod and open its settings.

3. Type the replacement text that you want transmitted as your minecraft:brand string.

4. Save the configuration and return to the main menu.

5. Navigate to the Multiplayer screen and connect to your chosen server.

During the connection handshake at login, the mod automatically injects your configured text into the minecraft:brand data packet, providing flexibility in how the server identifies your client.
