iPhone Privacy: 22 Practical Tips And Built-in Security Features

In an age where our smartphones have become extensions of our very beings, we carry within them a treasure trove of personal information, from emails to search histories and intimate conversations. The concern for digital privacy has never been more pressing. Whether you fear the overreaching grasp of corporations seeking to monetize your every digital move, or simply wish to shield your smartphone’s contents from prying eyes, the journey to fortify your iPhone’s privacy begins with a few strategic settings.

Smartphones, our modern-day lifelines, often seem like a Pandora’s box when it comes to privacy. Unbeknownst to many, your cell provider tracks your every move, and the exact extent of data collection by apps remains shrouded in ambiguity. The dilemma is clear – how can you balance the convenience of these devices with safeguarding your most sensitive information?

Enable Two-Factor Authentication

Two-factor authentication (2FA) provides an extra layer of security by requiring a secondary verification step in addition to your password. In the context of your Apple account, this means that even if someone knows your password, they can’t access your account without the second factor, which is typically a code sent to your trusted device. To enable 2FA on your iPhone, follow these steps:

  • Go to Settings on your iPhone.
  • Tap on your Apple ID (your name at the top).
  • Select Password & Security.
  • Tap Turn on two-factor authentication.
  • Follow the on-screen instructions to set it up.

Set A Strong Passcode (Consider Disabling Biometrics)

Your iPhone’s passcode is a vital line of defense against unauthorized access. While biometric methods like Touch ID or Face ID are convenient and secure for most users, you might consider using only a passcode in certain situations, especially if you’re concerned about potential legal or unauthorized access. Here’s how to set or change your passcode:

  • Open Settings on your iPhone.
  • Scroll down and select Touch ID & Passcode (or Face ID & Passcode for devices with Face ID).
  • Enter your current passcode if prompted.
  • Tap Change Passcode.
  • Follow the on-screen instructions to set a new passcode, which can be alphanumeric for added security.

Change Lock Screen Accessibility

The lock screen of your iPhone is your device’s first line of defense. It’s important to ensure that sensitive information isn’t easily accessible without proper authentication. Here’s how to customize your lock screen accessibility settings:

  • Open Settings on your iPhone.
  • Scroll down and select Touch ID & Passcode (or Face ID & Passcode).
  • Enter your passcode if prompted.
  • Under the “Allow Access When Locked” section, review the settings.
  • Disable features like Reply with Message, Return Missed Calls, and Notification Center if you’re concerned about unauthorized access.

Clean Up Lock Screen Widgets And Notifications

Your lock screen may display widgets and notifications, potentially revealing sensitive information. Customizing these elements can enhance your privacy:

  • Open Settings on your iPhone.
  • Navigate to Notifications.
  • Adjust the Show Previews settings based on your preferences.

Customization options include setting previews to appear “When Unlocked” or “Never.” This controls whether notification content is visible on the lock screen, adding an extra layer of privacy protection.

Audit App Permissions

Regularly reviewing and managing app permissions is essential for maintaining your privacy. Many apps request access to various hardware and system services, such as location, microphone, camera, and more. You may unknowingly grant permissions that compromise your privacy. To audit app permissions:

  • Open Settings on your iPhone.
  • Scroll through the various privacy controls in Privacy & Security.
  • Review each app’s permissions and adjust them as needed.

Pay particular attention to Location Services, as it’s among the most sensitive permissions that apps request. Ensure that apps only access your location when necessary, such as “Never” or “While Using.”

Use “Sign in with Apple”

“Sign in with Apple” is a privacy-focused feature that provides a secure way to create accounts on websites and apps. When you use this feature, your email address is hidden behind a randomly generated one. Here’s how to utilize “Sign in with Apple”:

  • When you encounter the option to create an account with your Apple ID, consider using it.
  • Besides the privacy benefit, you can manage your accounts using your Apple ID in Settings > [Your name] > Password & Security > Apps Using Apple ID.

By using “Sign in with Apple,” you can maintain control over your email addresses and easily audit where you have accounts.

Enable Automatic Updates

Keeping your iPhone’s operating system and apps up to date is crucial for security and privacy. Enabling automatic updates ensures that security and privacy fixes are applied promptly. Here’s how to enable automatic app updates:

  • Go to Settings on your iPhone.
  • Select App Store.
  • Toggle on App Updates to allow apps to update automatically.

iOS updates are typically set to update automatically by default, but you can verify this under Settings > General > Software Update.

Disable Ad Tracking

Ad tracking is a method used by companies to serve you personalized ads based on your online behavior. By disabling ad tracking, you can prevent some of your data from being shared with advertisers. To do this:

  • Open Settings on your iPhone.
  • Go to Privacy & Security > Tracking.
  • Ensure that Allow Apps to Request to Track is disabled.

Block Mail Tracking

Some emails contain tracking technology that can reveal when you’ve opened an email and provide vague location information. You can block this tracking in the Mail app:

  • Open Settings on your iPhone.
  • Go to Mail > Privacy Protection.
  • Enable Protect Mail Activity.

Configure Siri Settings

Siri, Apple’s voice assistant, plays a more significant role in your device’s personalization than you might realize. To fine-tune your Siri settings for privacy:

  • Access Settings on your iPhone.
  • Navigate to Siri & Search.
  • Review the list of apps and their permissions.

You can disable the visibility of certain apps in your device searches by tapping on the app and then disabling “Show App in Search.” If you don’t use Siri, you can turn off related features like “Press Side Button for Siri” and “Listen for ‘Hey Siri’.”

Turn Off iCloud Backup for Unnecessary Apps

iCloud backups are a convenient way to safeguard your data, but they may hold sensitive information. To enhance your data security, you can disable iCloud backups for certain apps:

  • Open Settings on your iPhone.
  • Tap on [Your name] > iCloud > Show All.
  • Uncheck any apps that you don’t want to be backed up online.

Set Messages to Auto-Delete

Over time, your message history can accumulate, and you may want to delete older messages for both privacy and storage space reasons. Here’s how to set your messages to auto-delete:

  • Go to Settings on your iPhone.
  • Select Messages.
  • Choose your preferred auto-delete option, such as 30 Days or 1 Year.

Enable Find My iPhone

Losing your iPhone can be stressful, but the Find My iPhone feature can help you locate your device or remotely wipe it if it’s stolen. To ensure it’s enabled:

  • Access Settings on your iPhone.
  • Select [Your name] > Find My.
  • Confirm that Find My iPhone is enabled.

With this feature enabled, you can use another Apple device to track or protect your iPhone.

Tweak “Shared with Me” Permissions

In iOS 15, Apple introduced the “Shared with Me” feature that displays links shared via text messages in corresponding Apple apps. However, this could lead to privacy concerns if shared links are accessible to anyone using your device. To customize these settings:

  • Open Settings on your iPhone.
  • Go to Messages > Shared with You.
  • Disable sharing in apps where you don’t want these links to be displayed.

By configuring these permissions, you have more control over what is visible in your apps.

Make Safari More Private

Safari is the default web browser on your iPhone, and you can take steps to enhance your online privacy:

  • Change your default search engine: Consider changing your default search engine to one that doesn’t track you. Go to Settings > Safari > Search Engine and select a private search engine like DuckDuckGo.
  • Disable tracking: In Settings > Safari, scroll down to Privacy & Security and enable Prevent Cross-Site Tracking to stop some sites from tracking your online activity.
  • Turn off ad measurements: You can opt out of ad measurements by disabling Privacy Preserving Ad Measurement.
  • Consider using an ad blocker: For more comprehensive ad and tracking blocking, consider using content blockers like 1Blocker or Ka-Block.

Consider Paid iCloud+ Features

In iOS 15, Apple introduced new pay-for-privacy features available with iCloud+ subscriptions. These features offer enhanced privacy protection:

  • Hide my email: This feature allows you to create randomized email addresses for online accounts, adding an extra layer of privacy. You can check and manage your email addresses in Settings > [Your name] > iCloud > Hide My Email.
  • iCloud Private Relay: This feature hides your IP address, making it more challenging for companies to build detailed profiles for targeted advertising. To enable it, go to Settings > [Your name] > iCloud > Private Relay.

Use Face ID/Touch ID with Attention

When setting up Face ID or Touch ID on your iPhone, ensure that the “Require Attention” option is enabled. This feature requires your eyes to be open when Face ID is used, adding an extra layer of security. To enable this:

  • Go to Settings.
  • Select Face ID & Passcode (or Touch ID & Passcode for older iPhones).
  • Enable Require Attention for Face ID.

Disable Significant Locations

Your iPhone has a feature called “Significant Locations” that tracks places you’ve visited frequently. While it can be useful for features like location-based reminders, it may raise privacy concerns. You can disable it:

  • Open Settings.
  • Go to Privacy.
  • Select Location Services.
  • Scroll down to System Services.
  • Choose Significant Locations.
  • Enter your device’s passcode if prompted.
  • Toggle off Significant Locations.

App Tracking Transparency

App Tracking Transparency (ATT) is a crucial privacy feature in iOS that requires apps to request your permission before tracking your activity across other companies’ apps and websites. You can manage these permissions in the following way:

  • When an app requests tracking permission, you’ll receive a pop-up notification.
  • Review the tracking request and choose whether to Allow or Ask App Not to Track.

iCloud Keychain

iCloud Keychain is a secure password manager that can help you create strong, unique passwords for websites and apps. It also securely stores your passwords and syncs them across your Apple devices. Here’s how to use iCloud Keychain:

  • Go to Settings.
  • Select Password & Accounts.
  • Choose Website & App Passwords.

You can generate strong passwords, store and autofill them using iCloud Keychain, reducing the risk of using weak or duplicated passwords.

Emergency SOS and Auto Call

In situations where you need to maintain your privacy and personal security, the Emergency SOS and Auto Call feature can be invaluable. It allows you to quickly contact emergency services and share your location with trusted contacts. To enable this feature:

  • Open Settings.
  • Go to Emergency SOS.
  • Enable Auto Call.

Hide Photos in the Photos App

If you have photos or videos you want to keep private, you can hide them within the Photos app:

  • Open the Photos app.
  • Select the photo or video you want to hide.
  • Tap the Share icon.
  • Scroll down and choose Hide.

To view your hidden photos, go to the Albums tab in the Photos app and find the Hidden album. This adds an extra layer of privacy to your sensitive media.

Privacy is an ever-evolving concern, and regularly reviewing and adjusting these settings can help you maintain a good balance between usability and data protection. While it’s challenging to eliminate all privacy risks, these steps can help you regain some control over your digital life and limit data collection.
