Hello @JebinPA ,

May I know which email address that you want to change/unbind?

If you are referring to the email address tied to a TP-Link ID, please note that it still cannot be changed, as each TP-Link ID is permanently linked to a single email address. This hasn't changed.

Since your old account is closed, here's what you'll need to do:

1. Register a new TP-Link ID using your new/preferred email address. You can follow this guide: TP-Link ID Explained: What It Is and How to Create One

2. Rebind your router to the new TP-Link ID. Since the old account is closed, the easiest approach is:
   • Connect the router to the internet.
   • Reset the router to factory defaults by holding the reset button until the power LED starts flashing.
   • Set up the router again and bind it to your new TP-Link ID.

Please note that if you have an active HomeShield subscription on the old account, it cannot be transferred to the new TP-Link ID — you would need to subscribe again under the new account.

Best Regards.
