ICloud login

Hey JemimaS,

I understand you're experiencing an issue with iCloud and FaceTime signing in along with syncing photos on one specific account. I'd be happy to help out.

In this situation, since you've isolated it to one account, I suggest using the steps here:

How to test an issue in another user account on your Mac - Apple Support

Be sure to look at the steps under "If the issue doesn't happen in the other account".

Cheers!

in user library > keychain the files are never deleted it will corrupt the keychain consult senior advisors in apple support https://support.apple.com/en-in/HT201232

The photos are not uploading see this article https://support.apple.com/en-us/HT204570

What happens when I go over my iCloud storage limit?

If you exceed your iCloud storage limit, photos and videos won't upload to iCloud and your library won’t stay up to date across your devices. To continue using iCloud Photos, upgrade your storage plan or reduce the amount of storage that you're using.

Reduce the storage for iCloud Photos by deleting photos and videos that you don't want to keep from your iOS devices or on iCloud.com. Your device will immediately remove any photos and videos that you delete and they won't be available for recovery in your Recently Deleted album.

If you're out of storage, your devices won't back up to iCloud, and new photos, videos, documents, and your information won't stay up to date.

Have you set up iCloud Keychain , after signing out from system preferences > iCloud what steps were followed , do you know the six digit iCloud verification code , which Apple ID are you using , is it example1@gmail.com or example2@icloud.com any screen shot please post ( hide your mail address ) .
