iphone 6s freezing; passwords
As far as I know, there is only one way to backup your passwords through iCloud: through iCloud Keychain. To check if your passwords are there, check all of the following:


On iOS: Settings > Passwords &amp; Accounts > Website &amp; App Passwords
On macOS: go to Keychain Access (/Applications/Utilties/Keychain\ Access), and on the sidebar to the left, there should be an entry called iCloud towards the top. Click on that, and sort by 'Kind', which should be the second column by default. Scroll down to the bottom, and you should see passwords with 'Web form password' in the 'Kind' column. Make sure that everything you want is there.
