I store all my passwords in Safari on my Macbook Pro (10.13.3), and use iCloud to share them with my iPhone. I noticed that some websites' passwords which I'd saved on my computer weren't showing up in my password list on the phone, so I went to the phone's iCloud settings, turned iCloud Keychain off and on hoping it would send all the passwords over. Instead it deleted all but a handful of the passwords on my phone. How do I get the Safari passwords on my Mac over to my iPhone?
