All games made or made available through Epic Games must be linked to an Epic Games Account. If for some reason, Fortnite happens to be your game of choice, you could already have an Epic Games account. This Epic Games Account can be used for both Rocket League and other games if you link the two platforms together. After you connect your accounts, information about your Rocket League items, Rocket Pass progress, Competitive Rank, and points will be displayed in your Epic Games profile.
