When you first launch Fortnite on your console, you’re given the option to start playing immediately or provide information to create a full Epic Games account. If you opted to start playing immediately without creating an account, then a "nameless" Epic Games account was created, so you could play, but that account lacks some information: it doesn’t have your email associated with it or an Epic Games display name.
Note that the Epic Games account that was created and your PlayStation, Microsoft or Nintendo account are not the same account.
Upgrading to a full Epic Games account means that all your progress and saved data (e.g. the content of your locker and gameplay progression) can be brought with you if you play on a new platform and/or on multiple platforms. For example, if you have been playing on one Console, but would now like to play on PC, you will need to upgrade your Console account in order to bring your Console progression to PC.
This article will explain how to upgrade a console or platform account to a full Epic Games account. If you already have an Epic Games account that you would like to link with your console account, please follow the account linking instructions.
NOTE: You may need to enable pop-up windows on your browser.
Your console or platform should now have a fully functional Epic Games Account associated with it. If you want to play on additional consoles or platforms and keep your progression, please follow the instructions for account linking.
If you get this error message when attempting to promote a console account it means that the email address is already in use on another account.
You can free up the email address by following the instructions in the article "How do I change the email on my Epic Games account?"
If you get this error message it means that your password was incorrect when attempting to link your console to an existing Epic Games account
