As of September 11, 2020 users will no longer be able to access their Epic Games accounts via Apple ID in the wake of their ongoing legal feud. If you’re someone who was using an Apple ID to sign in to an Epic Games account, including for use in Fortnite, you need to update your email and password as soon as possible.
Detailed directions for how to do this can be found on Epic’s site, but the gist is that you’ll need to head over to your general settings with your Apple ID and change your email address to your most current, non-Apple ID one. It’s going to be a similar process when it comes to setting up an Epic Games password. Visit the change your password page, login with your Apple ID and enter a new password.
It’s going to be easiest to get this done before September 11, but if you don’t do so in time there will still be hope. To reset your email after Apple support has ended, go to the Epic Games Contact Us page and follow the prompts. You’ll also need to have the verification code Epic is sending out via an email with the subject “IMPORTANT! Epic Games account update required for continued access.” The code looks like this: ABC-123-DEF.
