Help please

Hello, I have an iPod touch 4th gen and every time I try to access my account or redeem a promo code, it will repeatedly ask me for my password. I can downloa apps normally. I'm not sure what could be causing this. Any ideas are greatly appreciated.

Go to the settings app >> store >> log out of your apple ID. Then log back in. That fixed it for me when I had the issue with an app awhile ago.
