Your Zwift user ID is something you need for two important purposes: logging in to ZwiftGPS and signing up at ZwiftPower.

In this post – the first of a series – I show you how to find it in a secure manner.

Part One: The log file holds the truth…

… or at least it contains your Zwift user ID hidden among the many log lines. This makes it very easy to find your user ID. Here are a couple of way to do it without you having to read through the log file yourself.

cmd /k find /i "player id" %UserProfile%\documents\zwift\logs\log.txt
