Do You Know Who Has Access to Your Gmail and Facebook?

Gmail users should go here  to see every app that has privileges to access their account. To see what specifically each app has access to click it and the window will expand with details. While you can't adjust the level of access, you can remove the apps and services you no longer want.

Users should also check what third parties they've given access to their Facebook account. To do that, go to settings, then apps, then edit. Under "Apps websites and plugins," users should click disable. Facebook users should also go to "Apps Others Use," and click edit and clear that out as well.

Keep in mind that not everything that has access is insidious, but each user should be able to judge that for themselves.
