iPhone Security Tips

Posted on 24 July 2014.


Apple's iOS is well known for being save, but that doesn't mean the iPhone is impervious to security attacks.

  • Enable an alphanumeric password
    Using alphanumeric, mixed-case characters in a password of indeterminate length will increase the potential combinations exponentially, making your passcode tougher to decode.
    Much better then a four-digit numeric passcode.

    1. Go to Settings

    2. Select "General."

    3. Tap "Touch ID & Passcode."

    4. Toggle off "Simple Passcode."

    5. Key in your existing passcode.

    6. Enter your desired password. Pick one that's a mix of numbers and upper- and lower-case letters, and make it at least eight characters long.

    7. Confirm your password by typing it in again.

    8. Hit "Done" at the top right.

  • Prevent Control Center from appearing on top of the lockscreen
    If your iPhone makes it possible to access Control Center from your lockscreen, thieves could easily set your phone to airplane mode and prevent you from remotely wiping your device. Turn this feature off to keep your data safe.

    1. Go to Settings

    2. Select "Control Center."

    3. Toggle off "Access on Lock Screen."

    That's it. You'll know if Control Center is accessible from your lock screen if you see a small horizontal bar at the bottom of the page. If you did everything right, the bar should no longer be there.

  • Disable Siri access from lockscreen
    Holding down the home button on the lock screen activates Siri, which could let a malicious user make calls, access your contact list and even post to Facebook on your behalf. Disable this feature to prevent such attacks.

    1. Go to Settings

    2. Select "General."

    3. Tap "Touch ID & Passcode."

    4. Enter your password, then hit "Done."

    5. Toggle off Siri under the "Allow Access When Locked" section.

    6. While you're at it, you can also toggle off Passbook access to make sure no one can get to your sensitive information without first unlocking your iPhone.

  • Enable Find My iPhone
    If you ever worry about losing your phone and your sensitive information getting into the wrong hands, Find My iPhone could be a lifesaver. The feature lets you triangulate your missing device's location, and, if necessary, locks your iPhone and displays a message. This feature only works if you've enabled it prior to losing your handset, so make sure to turn it on as soon as you get your iPhone.

    1. Open the "Find My iPhone" app. It comes pre-installed in new devices. If you don't have the app, you can download it from the App Store.

    2. Sign in with your Apple ID.

    3. Go to "iCloud" in the Settings app.

    4. Toggle on "Find My iPhone." This lets you remotely locate and lock your device later.
