One of the first questions iOS 12 asks during initialisation is whether owners would like to turn on automatic iOS updating. Updating happens anyway with each major update, but without automatic updating it’s still possible to miss fixes for security issues that pop up between versions.
An interesting recent example of this is the offered in July to turn on USB restricted mode in response to techniques believed to be used by GrayShift and Cellebrite – it’s turned on by default in iOS 12 but users who enabled automatic updating could have had it two months ago.
Our advice is to turn this on! You can do this manually by going to Settings > General > Software Update while USB Restricted Mode is enabled via Settings > Touch ID & Passcode (Face ID & Passcode on the iPhone X) > and make sure the USB Accessories toggle is off. This will require the device to be unlocked before connecting USB devices in future, which some might find inconvenient – see of the feature for background.
Another welcome edition: Users of third-party password managers can now take advantage of the autofill feature without having to resort to tedious cut and paste or Share Sheets. LastPass, iPassword, Dashlane and Keeper have issued updates to reflect the new API that makes this possible.
This must be enabled manually via Settings > Passwords & Accounts and activating Autofill Passwords. Authentication using Face or Touch ID is still required.
