Blistur – Invite All For Facebook - Invite friends to pages, groups and events by one click! Review

I downloaded it and launched it. A vague screen comes up asking for a password. What password? I haven't done anything yet. So I try some passwords.. Like the one I use to purchase at the Apple Store. Nothing works. Just says password incorrect. Is this a phishing scam?
