2 factor authentication
If I change my password (not my user name)
to an existing apple id I use for iCloud, do I need to change the 2 factor ?19 character password generated by Apple to use my third party app that uses iCloud?
Thanks
From the article below.
Any time you change or reset your primary Apple ID password, all of your app-specific passwords are revoked automatically to protect the security of your account. You'll need to generate new app-specific passwords for any apps that you want to continue using.
