Security and general settings

Once you're more familiar with the iPhone, you may want to take some time to review and customize your device's settings. Settings control everything from the way your iPhone works to the data it shares with apps and other devices. You can open Settings by tapping the icon on your Home screen.

Settings gives you easy access to many different things, including settings for your notifications and privacy. In this lesson, we will focus on the Touch ID & Passcode, General, and Privacy sections.

Face ID, Touch ID, and Passcode

In the Settings app, you can also customize the security for unlocking your iPhone. By default, all iPhone models require a passcode to unlock them. Older models that have the Home button also allow you to unlock your phone using your fingerprint with a feature called Touch ID.

However, the iPhone XS and XR no longer have a Home button, meaning they can't read fingerprints. Instead, they use a feature called Face ID, which unlocks your phone by scanning your face with its camera.

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.

  1. Tap the Settings icon on your Home screen, then tap Touch ID & Passcode or Face ID & Passcode (depending on your iPhone model).
  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 Touch ID:

With older iPhone models, 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 Touch ID.

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

General

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

Using Screen Time to set restrictions:

Restrictions act as parental controls. You can use this feature to limit kids' time on the iPhone, set passcodes, and more. Restrictions can be turned on and changed in the Screen Time section of the Settings menu.

  1. Tap Screen Time, then Turn On Screen Time.
  2. Tap This is My Child's iPhone.
  3. Set a Start and End time for when your child can use their iPhone, then tap Set Downtime.


  4. Choose categories that you'd like to place time limits on for your kids, then tap Set App Limit.


  5. Enter a passcode that you can use to unlock the iPhone when you want to change any Screen Time settings or allow your children to have more time on the device.


  6. You can access and change more advanced settings in the Screen Time section of the Settings menu.

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.

Privacy

Third-party apps sometimes request access to your personal information. For example, an app might request access to your Twitter account to make it easier for you to share things with your friends. Another app might request access to Contacts to help you connect with the people you know.

Apps will ask for permission before accessing your information for the first time. However, you can always manage these settings under Privacy.

To manage your privacy settings:

  1. Tap the Settings icon on your Home screen.
  2. Tap Privacy.
  3. Tap an item to view which apps (if any) have requested access to your information.
  4. Turn controls on or off to enable or disable access for certain apps.

Location Services

Location Services is an optional setting that uses Wi-Fi and/or your cellular signal to determine your current location. Location data can be extremely useful for a variety of apps. For example, the Maps app can use this information to give you directions from your current location, while the Weather app can give you a local forecast.

Location data can also be used in ways you might not expect. For example, the Camera app can use it to tag photos and videos with their exact location (known as geotagging). If you then post a photo publicly online, you're also sharing the location data for that photo.

While it can be useful, some users may not feel comfortable sharing their location data in all of these situations. Fortunately, you can turn off Location Services for individual apps or for all of your apps. To modify these options, go to your Privacy settings and tap Location Services.

To limit ad tracking:

Some third-party apps may use information from your iPhone to serve you targeted advertisements based on your interests. These interests are based on the way you use your iPhone, including your browsing history and installed apps. If you'd prefer not to receive targeted advertisements, you can limit ad tracking. This feature won't limit the number of ads you receive—it will simply stop third-party apps from using your personal information.

  1. From Privacy, scroll down and tap Advertising.
  2. Turn the control on to limit ad tracking.

Bluetooth settings

You can connect your iPhone wirelessly to Bluetooth devices. For example, you could connect with a Bluetooth headset for hands-free calling.

To connect a Bluetooth device:

  1. Tap the Settings icon on the Home screen, then tap Bluetooth.
  2. Tap the control next to Bluetooth to turn it on. Your iPhone will scan for Bluetooth signals and list available devices.
  3. Select the desired device.

If you're still having trouble pairing your Bluetooth device with the iPhone, review this support page from Apple on third-party Bluetooth accessories.
