Given the recent problems with website accounts caused by the Heartbleed bug, we continue to talk about online security, signaling the possibility, for many services, of leaving a session also from another computer, remotely. So if you use a friend's PC or a public computer, you log in to Facebook and Gmail, but you forget to log out of your account, you can use your PC to do it.
So if we have left access to our personal account open on a PC not ours, it is important to know that, for services such as Gmail, Facebook, Microsoft and Twitter, it is possible to log out (logout) that account remotely, using another computer .

1) To exit Gmail remotely
Gmail makes it very easy to see active sessions on your account and end them.
Then log in to Gmail, scroll to the bottom of the page and notice that Gmail tells us when there was the last activity.
Click on the word Details to find out which open sessions there are, from which device and from which countries they have been started.
With the button at the top, you can exit all sessions at once, except of course the active one.
This mode is supported only via web browser and not by the various mobile apps.
This means that if you used Gmail on your Android phone or iPhone and this was stolen or lost, anyone can access our email.
To exit the registered Gmail on the lost Android or iOS device it is necessary to take more drastic measures and disconnect the entire Google account from the phone.
From the browser then go to Google Account Settings and then to the Security tab
Under Account Permissions, click View All to get the list of devices and applications that use the Google Account.
Select Android and then press the Revoke Login button on the right.
However, note that this disconnects the phone from the account and therefore makes it impossible to find it using the tools of Google Device Manager, which should be the first thing to use in case of loss to find or block it.
2) Log out of the Facebook account remotely, from another computer
To disconnect a Facebook login, go to Account settings in the Security section.
Click on Edit in the " From where you are connected " option, scroll down to see all the active sessions, expand the various lists to choose which active sessions to end.
At the top of the list you can also press "end all activities".
You can quickly log out of Facebook applications on your mobile phone by changing your account password.
Once the password is changed, Facebook will ask to register on all other devices.
3) Exit Twitter remotely
Twitter allows you to exit active sessions opened from your Android phone or web browser by changing your account password.
Go to the account settings and under password, reset the password.
Unfortunately, access from the iPhone and iPad app will remain open for which there is no way to exit remotely.
4) Microsoft / Outlook.com
Outlook.com doesn't have a way to exit an active session, but it does allow you to see recent activity.
On the Outlook.com website, open the options with the button at the top right and then enter the account settings.
You can then open the activity page on your account to find out all the connections made.
For each of them you can click the " It wasn't me " button which should end the session.
4) Other online services
Linkedin allows you to exit all sessions by changing your password.
The same should be possible with the Yahoo account which is similar to the Microsoft account, it has no options to disconnect remotely active sessions.
In general, to avoid problems of unauthorized access and not to have the anxiety of logging out of the account when using a computer not really, and also to rest assured that the password is not stolen with some software, it is convenient, for all these services, activate password protection with two-step verification on all sites, as explained in another article.
