To generate the default login password of an Xfinity Router, you need to reset the router. Once the reset is complete, you can do the Xfinity default router login to change the password, if required. Here’s how to reset the device:

1. Turn on the router by connecting its power adapter into the electric socket.

2. Locate the reset button of the router. Usually, it is situated at the rear end of the router.

3. Use a pointed object such as paperclip to reset the router. Press and hold the reset button for about 10 seconds and release it.

4. The status lights on the router will start flickering, and the router will restart.

5. Once the reset is complete, you can use the default login credentials to log into the admin console.
