how do I find out if my account was left open on another device?

[Gabriela]

I have lost my tablet device which I had logged on to my emails. Would it remain accessible if I didn't log off. How do I know if more devices have active access to email accounts?

What kind of e-mail?

[gregory]

Have you reported the tablet as lost if so then the company has deactivated internet access on it or they should have check with them.

All the mail services have an option in "settings" that says: log out from all devices. If you tell me what email you use I could be more specific.

Log into your email accounts (Facebook as well) and go to the Account Settings. In there you should see something like "Security" or maybe "Privacy" and then in there you'll see something about "Recognized Devices" or other Logged In places. You can delete all other devices or Sessions from that menu
