PlayerIdentityLogger
About
A lightweight Fabric *.21.11 client mod that reads the active Minecraft account identity when the game starts and writes the account username and UUID to the Minecraft log. It uses the client session already provided by Minecraft, performs no network requests, stores no personal data, and adds no commands, screens, or gameplay changes. The output is intended for troubleshooting, launcher verification, and mod development workflows where confirming the active account is useful.
