would apps on my phone open my facebook app? (iphone)?

[Josie]

Something strange is happening lately... my boyfriend claims that i am "always" on facebook when he logs on his mobile, my last active is ALWAYS 2-5mins, even in the middle of the night when i am sleeping and not even touching my phone. I understand that the last active should only show when i physically open the facebook app/facebook mobile website/messenger app etc.
How could my last active always be 2mins or 5mins ago when i didnt even touch my phone? my only theory is that some app must be accessing it? is it even possible? I am definitely not hacked, have already changed my password and checked the last active locations which all match my home credentials...

any help would be appreciated! thanks

Just go your facebook app.When you logout then turn off your chat manu.

ALWAYS read the permissions to ANY app you add to your facebook or that can access your account even when you are not online. Before accepting the app these permissions are always posted before you click accept. In many cases you can take this permission away from the apps and still use the app and some apps will require you to let them access and use your account as if they are you. That's probably what you are experiencing.
