Safari passwords disappeared, iClouds Keychain is not checked

Re-checking the Keychain option in iCloud system preferences solved it for me. No idea how it became unchecked.

Greetings, barbarafromburton.

I see that the usernames and passwords you've been keeping in Safari have disappeared. It appears that iCloud Keychain may not have been in use to sync the information but you'd like to get them back, and I'm happy to help.

Use Time Machine to restore deleted files or older files -- If you have a Time Machine backup when the information was still in Safari, this article provides the information and steps that you need.

Take care!
