If you use Windows 11 and have the Device Portal turned on, it lets you manage and test your device using a web browser. This is great for developers and advanced users, but if you don’t want others to access it remotely, you can make it safer by allowing only your own computer to connect.

What is Device Portal?

Device Portal is a special tool built into Windows 11 that lets you see and change settings, check your device’s performance, and troubleshoot problems from a web browser. You can even use it to test apps or software remotely.

Normally, it can be accessed from other devices on your network, but if you want to keep it private and secure, you can restrict it so only your own computer can use it.

Why Restrict Device Portal to Loopback Connections?

“Loopback” means your own computer only — basically, it blocks any other device from connecting. This helps protect your device from strangers or hackers trying to get in through Device Portal.

By doing this, only someone sitting at your computer can open the Device Portal, making it much safer.

How to Restrict Device Portal to Loopback Connections Only

Follow these simple steps to set it up:

1. Open the Windows Settings app:
   
   Click the Start menu button, then click Settings, or press Windows key + I on your keyboard.
   
   Learn more about opening Settings.
   
2. Go to the System section:
   
   When Settings opens, click System on the left side.
   
   

   

   
   
3. Open the For developers settings:
   
   On the right, click the For developers tile.
   
   

   

   
   
4. Turn on Developer Mode:
   
   Make sure the “Developer Mode” switch is turned on.
   
5. Enable Device Portal:
   
   Find “Device Portal” and toggle the switch to On.
   
6. Restrict access to loopback connections only:
   
   Below the Device Portal switch, turn on the option that says Restrict to loopback connections only.
   
   
   
   

   

   
   

Once you’ve done these steps, only your own computer can access the Device Portal. You can now close the Settings app.
