How 5 Hidden iOS Security Features Can Keep Your iPhone Safe

With the release of iOS 18, Apple has once again enhanced the robust architecture of iOS security features that further protect customers and their devices. While the average user is already taking advantage of standard security measures such as Face ID and two-factor authentication, iOS 18 introduces a range of lesser-known security features that can significantly enhance the protection of your device. Here, we explore five under-the-radar security features that you might not be using yet but should consider implementing to keep your iPhone safe. 

1. Lockdown mode enhances protection for high-risk users 

Lockdown mode, a new iOs security feature, is designed for individuals at heightened risk of targeted cyberattacks: high-level tech professionals, journalists, activists, or political leaders. This mode significantly increases the security of your device by restricting certain functionalities and services. When enabled, Lockdown Mode disables features such as message attachments, certain web technologies, and the ability to use wired connections to your iPhone. It also blocks incoming invitations from unknown users and restricts the use of unverified apps. 

To enable Lockdown Mode, navigate to Settings > Privacy & Security > Lockdown Mode and follow the prompts.

2. App privacy report uncovers covert app tracking 

The App Privacy Report is a feature that provides insights into how often apps access sensitive data such as your location, camera, and microphone. It also reveals which domains apps are contacting in the background. This transparency allows you to monitor and control app permissions more effectively. 

To access the App Privacy Report, go to Settings > Privacy & Security > App Privacy Report. Here, you can review detailed information about app activity and adjust permissions accordingly. By regularly checking this report, you can identify any apps that may be overstepping their bounds and take action to protect your privacy. 

3. Emergency SOS via Satellite is a lifesaver in remote areas 

iOS 18 introduces a groundbreaking feature: Emergency SOS via Satellite. This function is designed for use in areas without cellular coverage, allowing you to send emergency messages via satellite. If you’re in a remote location where traditional communication methods are unavailable, this feature can be a literal lifesaver. 

To use Emergency SOS via Satellite, simply press and hold the side button and one of the volume buttons. Follow the on-screen instructions to send an emergency message. It’s essential to set this feature up ahead of time by going to Settings > Emergency SOS and ensuring that you have your contact details and emergency information correctly entered. 

4. Passkey Support locks down login security 

Passkeys are a new type of credential designed to replace passwords with a more secure alternative. They use cryptographic keys to authenticate users, making them resistant to phishing and other common attacks. iOS 18 supports Passkey authentication, which can be used for logging into websites and apps that support this feature. 

To set up Passkeys, go to Settings > Passwords > Add Password > Use Passkey. Follow the instructions to create and use Passkeys for supported services. This feature simplifies the login process while providing an extra layer of security, making it harder for attackers to gain access to your accounts. 

5. Background app refresh control minimizes data leakage 

Background App Refresh is a feature that allows apps to update their content in the background, ensuring that you receive the latest information when you open them. While this is convenient, it can also be a potential security risk if apps are accessing your data without your knowledge. iOS 18 gives you more control over this feature, allowing you to restrict which apps can refresh in the background. 

To manage Background App Refresh, go to Settings > General > Background App Refresh. Here, you can choose to turn off Background App Refresh entirely or selectively enable it for specific apps. By carefully managing this setting, you can reduce the risk of unwanted data access and enhance your overall security. 

Distilled 

By taking advantage of Lockdown Mode, the App Privacy Report, Emergency SOS via Satellite, Passkey support, and Background App Refresh controls, you can enhance your iPhone’s security and ensure that your personal information remains protected in today’s digital age.
