Possible phishing attack tool?

I downloaded this, works great. 5stars *****

However, when an update becomes available (which is usually a good thing), this app and THIS APP ALONE demands that "verification required" beyond the usual appleID password request.

Why this additional request for a password? It feels like a phishing attack to harvest appleID passwords...

This company needs to explain why no other apps need this when updating apps via AppStore / iTunes
