Extra fun tip I'm sort of nervous putting out there just because it's a potential attack vector: if you used the same email address as your existing MyDisneyExperience account, guess what? The password you set while registering for Disney+ is now the password for your MDE account - they were "merged" without notification (that I saw). So not only is your Disney+ account compromised, potentially the account you use to…
TLDR: Disney+ wasn't actually hacked. But many people reused credentials from other sites that were already in account leaks.
