Settings/Safari/Saved Passwords/ it is possible to view all saved passwords by simply entering the 4 digit passcode on ones iPhone.
Is it possible to still be able to use Keychain passwords and autofill, but prevent access by the 4 digit code (e.g. requiring the full Keychain/iCloud password), so that someone who knows your phone code is not able to access all of your internet passwords in plain text?
EDIT: it is possible to set a different 4 digit code as the "Keychain pin" via turning on
Settings/iCloud/Keychain/Advanced/"Approve with Security Code", but the phone 4 digit code is still used for accessing the saved Safari passwords as above... It would be great if there was a way to always require the "Keychain pin" instead.
