In family sharing plan I am trying to change my daughters AppleID password but it says that "Because this is a new device, it can't be used to edit your account information yet." This is not a new device. How do I fix this?
iPhone 17 Pro Max, iOS 26
Wondering whose device you are using (yours, or hers) to change your daughter's Apple Account password.
Apple support's online article: Change your Apple Account password - Apple Support
Eg: says you can:
"Change your child’s Apple Account password using your iPhone, iPad, or Apple Vision Pro
If you have an iPhone, iPad, or Apple Vision Pro with the latest version of iOS, iPadOS, or visionOS and two-factor authentication turned on for your Apple Account, you might be able to change the Apple Account password for a child account in your Family Sharing group.
You can also change a child’s account password in Settings on their own device.
