Thank you thomas_r. I did what you mentioned, and in System Preferences, it said: "The App Store keeps OS X and apps from the App Store up to date." I did not realize that OS X updates are now being done through the App Store, so I updated preferences so OS X updates will automatically download. I hope now I do not get these sign-in messages, and my computer stays up to date!
i have my App Store set so that nothing is automatically downloaded, and I have never gotten the type of popup you mentioned. Depending on your system, you could end up with unwanted upgrades by using the automatic setting. The App Store recently updated EVERY instance of Evernote on my Mac Pro, rendering it unusable on two io the drives. There are a few updates that you might not want at all, such as iTunes 12. Setting it on automatic gives you NO control.
It is a fairly dumb updater. I was able to retrieve an earlier version of Evernote from a backup, but was not pleased at the behavior of the update process. Even Adobe's updaters aren't that bad.
