If you’re a user of Instagram, you may be wondering who’s logged into your account. To check this, you can use the Instagram app’s “log in” feature. Once you’ve logged in, open the app and look for the “username” field at the top left corner of the screen. If there is a name associated with that username (like “username1”), then that person is currently logged into your account. If there isn’t a name associated with that username (like “username0”), then that person is not currently logged into your account.
