I have more than 1 membership / pension record; do I need a login account for each record?

No. My NILGOSC Pension Online allows you to access all of your LGPS(NI) pension records. Once you have successfully registered and logged into my NILGOSC Pension Online, a notification will appear on the top right hand section of your screen if you have other employments. These can be accessed by clicking on the green arrow button and selecting the applicable employment from the drop down menu.
