If you received a text or email with a two-factor sign-in code or two-factor
authentication (2FA) code while logging in to your Epic Games account, use the
code to finish signing in to your account.
If you received a text or email with a 2FA code when you are
not logging in to your Epic Games account, someone else is
probably trying to access your account.
To keep your account secure, we recommend resetting your password immediately.
