CUPERTINO, Calif. —
TIP FIVE: FINGERPRINTING
With the new fingerprint ID system on the iPhone 5S, there’s no longer a reason to avoid protecting your phone with a passcode. I know passcodes can be very disruptive. I’ve often lost my train of thought before I could get to an app to jot something down. But your fingerprint now bypasses the need to type in a four-digit code in many situations.
It’s easy to set up. The iPhone will walk you through scanning one finger when you set up the phone. You can scan four more fingers — yours or someone else’s — by going to the settings. Go to “General,” then “Passcode & Fingerprint.”
I’m still confronted with passcode screens, especially when I need to authenticate an app purchase. It took me a few days to realize that even though you’re asked for a passcode, the fingerprint usually works unless the phone specifically tells you otherwise.
One more thing: The screen needs to be on for the fingerprint sensor to work. To save a step, just press on the home button firmly and let the button pop back up. But keep your finger lightly touching the button’s surface. The hard press will activate the screen, and the light touch will unlock the phone.
