How to secure your iPhone with Touch ID
Touch ID tries to balance convenience with security by letting you unlock your iPhone 5s with only a fingerprint. If the idea of frequently using a simple 4-digit passcode or strong alphanumeric password annoys you, Touch ID can let you enable one of those security methods while being able to easily, quickly get around it most of the time with just the touch of your finger. When you set up a new device, iOS will offer to walk you through Touch ID setup. Luckily, you decide against it at first, or turn it off at some point and then want to turn it back on, it's easy to do.
How to turn on Touch ID for the Lock screen
- Launch the Settings app from your Home screen.
- Scroll down and tap on Touch ID & Passcode.
- Enter your passcode if prompted.
- Under the Use Touch ID For section, turn On the option for iPhone Unlock.
If you've never used Touch ID before, iOS will take you through the fingerprint setup process. If you have, your existing fingerprints will once again be enabled.
