Local network access on an iPhone: What it is and how to enable it

What does "local network access" on an iPhone mean?

When an app requests local network access, it's asking to communicate with other devices on the same network, like a streaming app trying to discover cast-enabled devices. Without this permission, apps that need to communicate with nearby devices won't work correctly. Your phone can still access the internet via Wi-Fi or mobile data, but some device-to-device connections will be blocked.

If you're using a VPN on an iPhone, some features, like AirPlay, printers, or smart home devices, may not work unless your VPN allows local network access or split tunneling.

Why do apps ask to access the local network?

Apps need to access your home network for a few common reasons:

• To communicate with other devices on the same network, like printers or AirPlay-enabled gadgets.
• To discover cast-enabled devices for local streaming.
• To facilitate file sharing between devices.
• To manage smart home gadgets, such as lights, thermostats, or security cameras.

Basically, the app wants to extend its functionality beyond your phone and into your local environment.

Should I enable local network access on my iPhone?

Enabling local network access is convenient because it allows apps to connect to devices on the network seamlessly. But you should also consider security. Granting this access means the app can "see" other devices on your network. A malicious or poorly designed app could snoop or interfere with devices.

• Enable access for apps that genuinely need to interact with devices on your Wi-Fi, like streaming, printing, or smart home management.
• Restrict access for apps that don't have a clear need, such as games or simple utilities like a calculator. 

How to turn on local network access on an iPhone

Turning on local network access on an iPhone is simple:

1. 1.Tap "Settings" on your iOS device's home screen (iOS 14 or later).
2. 2.Tap "Apps" and find the app you want to manage.
   
3. 3.Tap the app and toggle "Local network" on.
   

If you want to manage permissions more broadly:

1. 1.Go to "Settings" > "Privacy & security"> "Local network" on your iPhone.
   
   
2. 2.You'll see a list of apps that have requested access.
3. 3.Toggle access on or off for each app individually.
   

Changed your mind after denying access? No problem — you can enable access anytime from your device's settings. Likewise, if you want to restrict an app, just turn "Local network" off in the same settings.

Best practices for local network security on an iPhone

Giving apps the local network permission makes your life easier, but it also comes with privacy and security risks. Follow these iPhone security tips to stay safe:

• Install apps from trusted sources. Stick to the Apple App Store. Avoid sideloading apps that bypass Apple's security checks.
• Review app permissions. Be mindful when apps request local network access. A simple calculator or flashlight app shouldn't need it.
• Keep your iOS and apps up to date. Updates include security patches that fix vulnerabilities.
• Secure your home Wi-Fi. Use a strong, unique password, enable WPA2 or WPA3, and follow other best practices for securing Wi-Fi networks.
• Use a firewall on your router. Most modern routers include firewalls. Make sure yours is active to prevent unauthorized access.
