Security and General Settings

Learn all about iPhone security and make sure your iPhone settings are where they should be in this free lesson.

Touch ID & Passcode

Under Touch ID & Passcode, you can customize the security for unlocking your iPhone. By default, the iPhone requires a passcode to unlock it. If you have an iPhone 5S or a newer version, you can also unlock your iPhone using your fingerprint with a feature called Touch ID.

To change a passcode lock:

When you first start up your iPhone, you'll be prompted to create a passcode lock. If you ever want to change it, it's pretty easy to do so.

  1. Tap the Settings icon on your Home screen, then tap Touch ID & Passcode.
  2. General settings will appear. Scroll down and tap Change Passcode.
  3. Use the keypad to enter your current passcode.
  4. The next screen will automatically appear, prompting you to enter a new passcode. Enter the new passcode. (You'll need to enter it twice to confirm.)

  5. Your new passcode will be set.

To set up TouchID:

With an iPhone 5S or newer, you can set your iPhone to unlock using your fingerprint. Instead of entering a passcode, you can simply place a finger on the Home button.

  1. Tap the Settings icon on your Home screen, then tap Touch ID & Passcode.
  2. Input your passcode, then tap Add a Fingerprint...

  3. Follow the instructions shown on the screen, and place a finger or thumb on the Home Button. You'll need to touch the Home button repeatedly until the iPhone gets a good read of your fingerprint.
  4. Your fingerprint will be added, and you can now unlock your phone with TouchID.

You can add multiple fingerprints to TouchID, allowing you to use any number of your fingers or thumbs to unlock your iPhone.


Under General, you can customize different settings that control your storage, accessibility, and overall preferences.

To set restrictions:

Restrictions act as parental controls. You can use this feature to set a passcode that will restrict access to certain content. While a passcode lock is used to unlock the iPhone, a restriction passcode is used to open specific apps and perform certain tasks. For example, you can restrict explicit music, limit the ability to make in-app purchases, and withhold access to important apps.

  1. In General, tap Restrictions.
  2. Tap Enable Restrictions.
  3. Use the keypad to enter a restrictions passcode. (You'll need to enter it twice to confirm.)
  4. Restrictions will be enabled. From now on, anyone who uses your iPhone will need to enter the passcode to access restricted content.
  5. Set the controls to green to allow apps to be used without restrictions.
  6. Scroll down to access more advanced restrictions, such as ratings for music, movies, apps, and more.

Updating your software

Software Update is where you'll download iOS updates from Apple. Updates frequently include bug fixes and other improvements designed to enhance your experience with the iPhone. If an update is available, tap Software Update, then tap the Install button.
