How to secure your iPhone or iPad from hackers, snoopers, and thieves (iOS 12.2)

13 of 20 NEXT PREV
  • Why secure your device?

    Why secure your device?

    Chances are high that your iPhone or iPad is an absolute treasure trove of personal information that you don't want falling into the hands of others. And while iOS does a great job of keeping data safe, it's possible to make the device a lot more secure.

    Here are settings you should check (and change) and tweaks you should make to harden the security and lock down your device.

    It's worth noting that extra security always puts speed bumps in the way of productivity, and adds additional steps -- along with a few seconds -- to doing things. Security is always a compromise, but  the small productivity downsides that arise from it are worth it to keep you and your data safe.

  • Start with a strong passcode

    Start with a strong passcode

    Security all starts by keeping people out of your device!

    No matter whether you use Touch ID or Face ID, you still need a passcode, and the longer the passcode you can use -- and remember! -- the better.

    Go to Settings > Touch ID & Passcode (or Face ID & Passcode on iPhones with Face ID), enter your existing passcode, and then tap on Passcode Options to get a set of options. Choose between Custom Alphanumeric Code (the most secure) or Custom Numeric Code (second best option), or 4-Digit Numeric Code (I don't recommend this last option because it's easy for shoulder-surfers to see what your PIN code is).

  • Set brute-force protection

    Set brute-force protection

    iOS has built-in brute-force protection to prevent an unauthorized user from trying to guess your passcodes.

    Go to Settings > Touch ID & Passcode (or Face ID & Passcode on iPhones with Face ID), enter your existing passcode, and scroll down to Erase Data.

    After 10 attempts (toward the end there will be a time lockout to slow down the entry process), the encryption key will be deleted and your data wiped.

  • Control access to what's accessible when the iPhone or iPad is locked

    Control access to what's accessible when the iPhone or iPad is locked

    Control how much -- or how little -- you want to be accessible on a locked device. iOS 12 gives control over the following:

    • - Today View
    • - Notification Center
    • - Control Center
    • - Siri
    • - Reply with Message
    • - Home Control
    • - Wallet
    • - Return Missed Call
    • - USB Accessories

    The bottom line is that the more you lock down, the more secure your device and data will be. The USB Accessories feature is especially useful, because it will prevent the Lightning port from being used to connect to any accessory if your iPhone or iPad has been locked for more than an hour.

    Go to Settings > Touch ID & Passcode (or Face ID & Passcode on iPhones with Face ID), enter your existing passcode to control this.

  • Use a VPN, especially over public Wi-Fi

    Use a VPN, especially over public Wi-Fi

    A VPN (virtual private network) allows you to create a secure connection between your device and the VPN service provider's server, allowing you to browser the web securely and in privacy without others being able to snoop on that you are doing.

    There a a lot of VPN providers out there, but one that I've used a lot and trust is F-Secure's Freedome VPN.

  • Control notification data leakage

    Control notification data leakage

    Notifications displayed on the lock screen can leak sensitive information to snoopers and shoulder-surfers. Here's how to prevent that from happening (it also means that you have to unlock your device to see any notifications, but that's the price of added security).

    To do this go to Settings > Notifications > Show Previews and change the setting to When Unlocked or Never.

    Disable unnecessary widgets

    Widgets can leak data even when your iPhone is locked. You can either disable the Today View from being accessible when your device is locked (see earlier tip: Control access to what's accessible when the iPhone or iPad is locked), or you can edit the widgets as follows:

    Swipe to the right on the Home screen into the Today View panel, and then scroll to the bottom of the screen and hit Edit. Now, you can remove any panel that you do not need.

  • Audit which apps have microphone access

    Audit which apps have microphone access

    Many apps request access to your microphone, so it's a good idea every so often to audit these apps to see if you are still comfortable with them having this ability.

    To do this head over to Settings > Privacy > Microphone and make changes as you see fit.

    Switch on automatic iOS updates

    Want to make sure that you are running the latest version of iOS? A feature in iOS 12 is the ability to install iOS updates automatically, which makes sure that your iPhone or iPad's operating system is always up-to-date.

    To set this head over to Settings > General > Software Update and turn on Automatic Updates.

    Password AutoFill and third-party password managers

    This, in my mind, is the killer security feature that Apple introduced in iOS 12.

    iOS 12 now comes with both a password autofill feature using the iCloud Keychain and has the ability to connect to third-party password apps such as LastPass, Dashlane, and 1Password. This means that you can get access to your passwords across a variety of operating systems.

    You can find this feature in Settings > Passwords & Accounts > AutoFill Passwords.

    Control what Touch ID/Face ID is used to authenticate

    Do you want the convenience of Touch ID or Face ID, or would you rather have the additional protection that having to enter your passcode offers? Again, it's balancing security against convenience.

    iOS 12 allows you to switch Touch ID/Face ID on and off for:

    • - iPhone Unlock
    • - iTunes and App Store
    • - Apple Pay
    • - Password AutoFill

    Go to Settings > Touch ID & Passcode (or Face ID & Passcode on iPhones with Face ID), enter your existing passcode to control this.

    You can choose between:

    • - Never
    • - While Using the App

    Each app should also give you a brief explanation of how if uses location data.

    To do this press the power button five times (just be sure to cancel the SOS Emergency calling feature if you have this activated).

    Audit location-based alerts, Apple ads, and suggestions

    Location-based alerts, Apple ads, and suggestions are all very convenient, but in exchange for this you are allowing your location to be tracked.

    I generally keep Location-Based Alerts and Location-Based Suggestions on, and disable Location-Based Apple Ads, but you can turn them all off if you wish.

    One of the best ways to protect your data is to set up and use two-factor authentication. This means that, even if an attacker has your iCloud username and password, Apple will send an authentication code to a device you've chosen, which should block most attacks.

    Go to Settings > and tap your name at the top of the screen, then go to Password & Security, then choose Two-Factor Authentication.

    From here, you can also check the Send Last Location feature, which sends the location of your device to Apple when the battery is low, allowing you to find it even when the battery is flat.
