Hello @salmansidd17  @dlk7 

When linking the TP-Link router to your Google Assistant, you should be able to set a PIN code as follows.

You can change this PIN code as you like, just make sure you can remember it:

I was confirming this and taking the screenshot on the TP-Link Tether App.

You may tap the three-line icon on the top-left, then navigate to Smart Life Assistants. You will see IFTTT, Alexa, and Google Assistant.

If you still cannot find it, please check the below steps or details:

1. Try to login to the device on the Tether App, then check again if you can get the Google Assistant under Smart Life Assistants.

2. Still no? Please make sure you are using the latest Tether App, and show us the detailed version.

3. What is the hardware and firmware version of your TP-Link router, is it also Archer AX55? Please update and install the latest firmware.

Thank you very much.
