Tp-link plug hs103

HA newbie. I have installed haos in a VM. I am starting small. I powered up a tp-link light and a plug. HA discoveres them. Integrating the light just required a couple of clicks and I was good to go. When I try to integrate the plug HA wants a user and password. I tried the credentials that I use for the tp-link app but that doesn’t work. Before you ask, yes I checked the case. What am I supposed to use for a username and password.
