All my saved passwords have been deleted now cannot get into any of my emails or social media’s

Hello Chels_17, 

Thanks for reaching out on the Apple Support. From your message I understand that you're not seeing any of your saved passwords on your iPhone. I know how important it is for me to have my account information available on my own iPhone. 

Begin by following the steps under, "If you don't see your iCloud Keychain items," section from this article: If iCloud Keychain won't turn on or sync. 

If you happen to have any other Apple devices that you use iCloud Keychain with, check and see if the passwords are showing on the other devices. 

All the best.
