Hey, so a couple of months ago, my bro lent me his iPhone since mine had issue. I changed the apple ID on the device so I was able to access my keychain...along with his keychain. Which means when I go to a website I can choose to log in as him since the password would be pre-filled for me (both iphone and MacBook air).

Now that the iphone has been returned to him, I wonder whether he could log in to website as me also? Is there a way to make sure only my devices are able to use the keychain or have my password pre-filled?

Should I just erase keychain and rebuild?

I am afraid that we have commingled keychains that both of our Apple ID account contain passwords of each other.
If you saved your passwords to his Keychain while his iCloud account was active on there, I don't see any way to unwind that short of physical access to the phone to remove them then.

What if I change password to websites / apps that I frequent? will the new passwords get updated on his keychain too?
