To log in to Disney Plus with a code, open the Disney+ app on your device and select "Log In". A 8-digit code will appear on your screen. On a separate device, go to disneyplus.com/begin using a web browser. Enter the 8-digit code and click "Continue". Sign in with your Disney+ account credentials, and your device will automatically log in. Ensure your device has an active internet connection. If the code expires, refresh the app to generate a new one. This method is useful for logging in on smart TVs, streaming devices, and gaming consoles.
