Your Zwift ID is a unique number assigned your Zwift account. It is used by ZwiftPower and other third-party apps to connect those apps to your Zwift data.


Your Zwift ID can be found in the desktop version of Zwift by going to Documents->Zwift->CP. The folder names here (eg, “user123456” use the ID’s of every Zwifter who has ever used your computer.

If you see multiple folders and are unsure which one belongs to your account, look at the dates of the files inside the folder, which will correspond to dates you have used Zwift on this computer.


Zwift for iOS presents a challenge because you cannot simply browse your iOS device’s file system to find your ID. The ever-helpful Christian Wiedmann discovered this solution:

  1. Log into in Safari
  2. Scroll to the last “Connect Your Account” button at the bottom (For “Today’s Plan”)
  3. Hold your finger on the button until the menu pops up. Your Zwift ID is the number at the end of the URL.
