Where can I find my CD Key for Ubisoft Connect?
You don't need a product key to play games that you purchase directly from the Epic Games Store.
If you are asked to provide a CD key when you try to play a game through Ubisoft Connect, please follow the steps outlined in the Ubisoft article Request to activate a game key when launching your game (Opens in a new tab)
If you have activated a game key or code and you’re asked to provide it during a gaming session you can find it in Locating your activation key in Ubisoft Connect PC (Opens in a new tab).
