If you're unable to sign in to your FX Account, first try resetting your password by clicking on the “Need help signing in?” link on the account sign in page. Please note that some users may need to reset their password due to the account migration that took place as a part of The Walt Disney Company’s acquisition of 21st Century Fox.
If you do not receive a password reset email, please check your spam folder. Otherwise, consider whether your FX Account is registered to a different email address and try signing in again.
