Replace a Bannerlord dedicated-server authentication token

Make the change

1. Launch Bannerlord multiplayer on your own computer and sign into the lobby.
2. Open the in-game console with Alt + ~ and run customserver.gettoken. TaleWorlds writes the token into Documents/Mount & Blade II Bannerlord/Tokens.
3. Stop the hosted server. Open the token file locally and copy its contents into Auth token in Startup, keeping the token private.
4. Save, start and check Console for authentication and session-start messages.
5. Join through the matching multiplayer client to confirm the hosted session is available.

Check the result

If authentication fails, check that you copied the token contents rather than its filename. TaleWorlds documents token expiry after three months; generate a replacement when it expires. Keep the existing mission configuration and save files while fixing authentication.

This template exposes Auth token and Auto update. Match rules are read from the launcher-selected tdm_config.txt, not invented name/password fields.
