This account is required to sideload apps on LG WebOS TVs. It’s free, takes about 3 minutes to set up, and you only need to do it once. After completing these steps you’ll have a passphrase to enter in your DisplayHUB controller to install the app automatically.

On your LG TV:

  1. Open the LG Content Store (press the Home button on your remote and look for the store icon).

  2. Sign in with the LG developer account you just created.

Enable the Key Server and Get Your Passphrase

After the TV restarts, open the Developer Mode app again.

  1. Confirm Dev Mode Status is still On.
  2. Toggle Key Server to On.
  3. A passphrase will appear on screen — note it down or leave the app open.
⚠️ Keep the Developer Mode app open on your TV during installation. The Key Server session expires after roughly 50 hours. If you ever need to reinstall, toggle Key Server back on to get a fresh passphrase.
💡 Both Dev Mode Status and Key Server must be On at the same time for the DisplayHUB installer to work.
