Win Popup Handler - Sign In Process

I am using Win Pop-up Handler in Sign In process. But, user name and password provided are not populated in popup and its not signing in. Can any one help, how to handle the popup in signin process. I have shared screenshot like how sign in page looks.

Try using parallel activity. On LHS of parallel activity put the click interaction (on which this popup comes), On RHS of parallel activity put a delay activity followed by popup handler activity.

thanks @ashishJ. Will try this. For now, i have passed username and password in URL, since am using chrome.
