Hi, be indulgent, I am new here..

My problem:

I have a Google Home Mini and an Android Phone with Kasa app.

I have bought an TP-link HS100 few months ago, installed the Kasa app, and all went well with Kasa and Google home following instructions.

Few days ago, I bought another HS100, add and configured the device using the Kasa app .. working fine ... But cannot  associate with the Google Home using the Home app.  The kasa app has no remote autorize button as shown on FAQ.

I am facing a strange problem: a windows open asking to "authorize" kasa to control the device and ask for my Kasa account.

When entering username and pwd the app says invalid pwd.. (The same for the kasa app).

I have done this multiple times, reseting my kasa pwd .. same issue. My pwd is rejected.

I am lost.

Thanks to help me
