THx to leo, my problem's solved. I had a download pending, i remebr a while ago while d'loading an app i did something and the app didnt fully diownload. But i jus couldnt remebr which one was that. SO i checked my mail as appstore sends u reciept for the apps u downloaded. And i found out that particular app downloaded it again. Now everythings working as normal, no more password prompt evrytime i open appstore.
So if you have the same issue, try this and it should be fine.
Cheers!
