Keychain iCloud copied bye mistake to another iCloud account
Hi apple community.
Really hope some one can help me understand what is going on.
I have twice experienced the following scenario.
example: On my iPhone I’m logged into my iCloud account. I click keychain OFF within iCloud settings. I sign out of iCloud. Then I sign in with another iCloud account (my daughters). Now all my keychain passwords are copied to my daughter’s iCloud account!!!
Why does this happen? And more importantly how to avoid keychain passwords to be copied from the phone to ANOTHER iCloud account just because you sign into another iCloud account on the iPhone.
iPhone 8, iOS 15
