How can I secure my iPhone, iPad, or iPod touch?
To secure the data on your mobile device, you should always use a pattern, PIN, passcode, or password to lock it. If the device is lost or stolen, this precaution can prevent others from accessing your email, calendar, contacts, and other data. See How can I protect data on my mobile device?
Using the Passcode Lock feature
Every iOS device provides a Passcode Lock feature that lets you set a four-digit passcode for locking the device. On a device running iOS 4 or later, you can choose to set either a simple four- or six-digit passcode or a variable-length alphanumeric passcode.
To use Passcode Lock on your iOS device:
- From the home screen, tap , and then choose either or .
- To set an alphanumeric passcode, which is more secure, do the following:
- In iOS 9, tap . If you already have a shorter passcode set, instead tap , then enter your current passcode. Tap . Tap .
- In older versions, if is an option, turn it off. Then tap . If you already have a simple passcode set, instead tap , then enter your current passcode.
- Enter your passcode, tap About your IU passphrase and At IU, how can I choose a secure PIN? , re-enter your passcode to confirm it, and then tap . For guidelines on setting a secure passcode, see
- To select how long the device will remain idle before requiring your passcode, tap , and then choose an option. The shortest time provides the best security. If you have a device with Touch ID and are using it to unlock your device, you will only have the option to require a passcode immediately.
With Passcode Lock turned on, you'll see "Data protection is enabled" at the bottom of the "Passcode Lock" screen.
If you forget your passcode, see If you forgot the passcode for your iPhone, iPad, or iPod touch, or your device is disabled.
Enhancing standard security
Hardware encryption is built into iOS 4 and later, and is a standard feature on the iPhone (3GS and later), iPad (all models), and iPod touch (third generation and later). To enhance the standard security of your iOS device:
- Enable Passcode Lock's option. To do so, on the "Passcode Lock" or "Touch ID & Passcode" screen, turn on , and then tap . With this option set, your device will securely erase all data after 10 failed passcode attempts. (To restore data to your device, connect it to the computer you use to sync it.)
- When backing up your device data to a computer, use the encrypt backup option in iTunes. UITS recommends setting a password that uses a combination of letters and numbers, and saving it in your Keychain.
- If you use iCloud to back up your device data, make sure to use a strong iCloud password.
Important:At Indiana University, if you use your device to access or store protected health information (PHI) regulated by the Health Insurance Portability and Accountability Act of 1996 (HIPAA), do not use a non-IU cloud service (e.g., iCloud or Google) to back up your device data (regardless of the strength of your password). For more about working with PHI at IU, see At IU, which dedicated file storage services and IT services with storage components are appropriate for sensitive institutional data, including research data containing protected health information?
Additionally, iOS 5.1 (and later) supports the use of S/MIME Client Certificates to digitally sign or encrypt email messages. At IU, Client Certificates are provided by the InCommon Certificate Service. For more, see Using S/MIME Client Certificates with iOS devices.
Wiping data from your device
To remove all personal data from your device, see How do I clear all data from my iPhone, iPod touch, or iPad? You can restore your device by connecting it to the computer you use to sync it.
At Indiana University, if you have configured your device to connect to Exchange, you can use OWA to wipe your data remotely if your device is lost or stolen; see In Outlook Web App, how can I manage my Exchange ActiveSync device?
