I need help retrieving old Authentications

I need to retrieving the authentications I had, back before I removed this app I have a few on there, since then Ive accidentally deleted the app. I thought I would be able to get my stuff back since it had the Cloud symbols when I went back to download it but NO. ALL GONE, with no way to retrieve now I cant access account? PLEASE HELP!
