iPhone Lockdown Mode in iOS 26: How It Works

Apple labels Lockdown Mode as an optional, extreme protection feature that reduces your iPhone’s exposure to digital threats by limiting certain features and functionality.

Smartphones face many security risks, from phishing links to spyware that can silently install itself. Lockdown Mode aims to block the most advanced attack methods by restricting the phone’s normal behavior.

In iOS 26, Lockdown Mode works alongside other security upgrades like Background Security Improvements and Memory Integrity Enforcement to provide multiple layers of defense.

How to Enable

Open Lockdown Mode

This method walks you through turning on Lockdown Mode for your iPhone. Once enabled, it applies to your paired Apple Watch automatically.

1. Open the Settings app on your iPhone.
2. Tap Privacy and Security.
   
3. Scroll down and select Lockdown Mode.
4. Tap Turn On Lockdown Mode.
5. Tap again to confirm and choose Turn On and Restart.
6. Enter your device passcode when prompted.

Once your iPhone restarts, Lockdown Mode is active. Your device now runs with extra security restrictions.

Configure Exceptions in Lockdown Mode

Allow Trusted Apps or Websites

Lockdown Mode can block features you need for work or daily use. You can allow trusted apps and websites to bypass some restrictions if you are sure they are safe.

1. Launch Settings again.
2. Go to Privacy and Security and tap Lockdown Mode.
3. Choose Configure Web Browsing.
4. To exclude a website, add it under Excluded Safari Websites.
