My iCloud Keychain and passwords have started to appear on my mother-in-law's iPhone?

I have just bought a new iPhone and set it up last night. This morning I get a message from my Mother in Law telling me that all of my passwords have appeared in her Password and Keychain area. This happened a couple of years ago; I can’t link it to any specific event but at the time we deleted them and they didn’t update with any new passwords after that point. Fast forward to now and suddenly they have reappeared.

I have done a security check and I do not appear to be connected to her account in any way.

How can this happen and more

importantly, how do I stop it please??

Hi there ChrisW955,


The only way this could be happening is if your mother in law is signed in with your Apple ID on her device with iCloud Keychain turned on. We'd suggest having her check her Apple ID info in Settings.


If this behavior persists, you'll want to reach out to Apple Support directly for further assistance. They're best-equipped to take a closer look at the issue and provide some additional guidance. This link will help you get started: Apple Support


Take care.
