You Don’t Use Auto-Lock
Both macOS and iOS have an Auto-Lock feature built-in. If you leave your phone or computer behind (and don’t touch it after a set amount of time) they’ll lock themselves automatically. This helps to ensure that no one can grab your laptop or phone and get into it without entering your password or passcode first.
What to Do: Your best bet is always to lock your Mac or iPhone before you walk away; but in case you forget, Auto-Lock is a great failsafe.
- Open System Preferences.
- Click Security and Privacy. Enter your password if required.
- Click General.
- Check Require Password and select “Immediately.”
- Open Settings.
- Tap Display & Brightness.
- Tap Auto-Lock and select “30 Seconds” for maximum security.
