Keychain on Ipad

One final thought before you resolve yourself to seeking help, if needed, from Apple Support...

If you are confident that the keychains are now fully independent of eachother (as your tests now suggest) then you could simply delete all the account information that you don’t require from your daughters iPad. Simple - all done!

If you set-up the iPad using your own AppleID, prior to creating an AppleID and associated iCloud account for your daughter, it is likely that you created a situation whereby the two keychains were inadvertently merged - prior to your devices becoming independent of eachother. Having completed initial setup using your credentials, a copy of your keychain will have existed on this iPad. The merge is likely to have occured when you logged-out of your own iCloud account on your [about to be] daughters iPad - and you chose to “save“ a local keychain during the iCloud log-out process; when subsequently logging-in with your daughters AppleID/iCloud account on this iPad, the locally-saved keychain (containing your data) was merged with you daughters new iCloud account - hence your data appearing where it was not expected.

I hope you will be able to make some useful sense of this explanation. Good luck.

Due to the complexities associated with family/child/organiser accounts, you would be best advised to contact Apple Support directly. A short conversation with an Apple Support Agent will likely guide you to resolution - plus, if any back-end support is needed, they should be able to get this organised very quickly. I would be uncomfortable providing futher advice that might cause loss of your keychain - which, I assume, contains account information that you might have difficulty re-creating.

Possibly the best mechanism to initiate contact with Apple Support would be to install the Apple Support App on your own iPad. From here, at the bottom of the screen, select Get Support, then from More Topics choose AppleID and iCloud, then iCloud Questions and Troubleshooting. You should now be presented with the option to schedule a call with an agent. You’ll be assigned a case that can be managed from the Apple Support App.

If you do approach Apple Support, please report back your experience and any steps taken to resolve this issue; this information may be helpful to others.

Great to hear that you’re all sorted.

Whilst challenges like these are seldom perceived at the time as helpful, they can often present a useful learning opportunity. We can both file this as knowledge gained.

This may be dumb question, but are you certain that all services on your daughters iPad which are logged-on (such as iCloud, iTunes & App Store, Messages, Facetime) are logged-in with her own AppleID - and not yours?

Okay, once you have checked that your AppleID is not used for any services on your daughters iPad, you could try to purge the keychain - however, you should be conscious that this procedure is likely to wipe any credentials (if any) that relate to your daughter. If this is likely to be an issue, then it would be advisable to manually verify/copy, onto paper, any website/account details that you need to save from the local keychain on her iPad before proceeding further.

The significance of ensuring that your AppleID is not used for any services on your daughters iPad is that, with update to to iOS12, there have been reports of information (specifically messages) being combined between users that have shared an AppleID. That said, yours is the first report that I have seen myself that relates to possible merging of keychains.

If/when ready to proceed, attempt to log-out from iCloud on your daughters iPad; when asked if you want to save a local copy of the keychain, you should answer no; this should flush your local (but encrypted) keychain from the iPad.

After waiting for a minute or so, you can log-in to iCloud on your daughters iPad with her AppleID; your daughters cloud-data should re-sync. Assuming that your daughter's AppleID is not logged-in on another device, then no keychain data should exist in the cloud or on the iPad (as we didn't save a local copy when logging-out of iCloud).

If data from your keychain seems to re-appear, it is worth exploring the possibility that you inadvertently merged both keychains at some point. This can be verified by creating a new credential for a website on your daughters iPad; if the new account can be seen within the keychain on her iPad - but not yours - then the keychains are independent. If this is happens - and you're certain that her keychain is now independent of your own - then you can manually delete unwanted entries from your daughters keychain.

If it transpires that a keychain merge has occurred, we can discuss the mechanics of how this may have happened.

If your keychain content somehow remains linked with your daughter AppleID, you should contact Apple Support for advice. Your keychain contains private information that should not be exposed beyond your own account - it is not shared with other accounts.
