How To Log Yourself Out Of Facebook On Other Devices And Improve Your Security [Weekly Facebook Tips]

Ads by Google

For many Facebook users, it’s good to occasionally brush up on your security knowledge and see if there’s a better way you could be doing things. Despite Facebook’s tendency to expose your information as publicly as possible, they do take your login security seriously – and you should too. Do you know how to log out of Facebook remotely? Have you authenticated certain devices with Facebook so that you can be notified if someone tries to log in on another device?

These are things you can easily set up and which will help you to maintain control over your Facebook security. If you haven’t yet done so, take five minutes to read this guide and improve your security on Facebook now.

Accessing Your Facebook Security Section

All of the security tools are easily located within the Facebook Security section. Go to the arrow on the top right of Facebook, choose “Account Settings” and then “Security”.

Remotely Log Out Of Facebook

In the Facebook Security section, you’ll see a section called “Active Sessions”. Clicking on that will show you all the places you are currently logged into Facebook. You should see your current session, followed by any other devices which are logged in as you. This could include your mobile, tablet or work computer.

For instance, if you’re at home and you can see you’re still logged in at work, you can click on “End Activity” to ensure none of your co-workers do anything silly or sly with your account. Other useful scenarios could involve leaving yourself logged in at a friend’s house or on a public computer.

The same goes for any device you don’t recognise, as it could be someone accessing your account. Just click “End Activity” and it will log you out from that device. If you accidentally log out your own phone or tablet it’s no big deal to log in again from the device when you’re ready to use it again.

Set Your Recognised Devices

Facebook allows you to register your usual computers and devices so that it knows that it’s quite likely to be you logged in from that machine. It also allows you to approve or get notified if anyone logs in using any other device. To set up your recognised devices, you need to activate “Login Approvals” and add your devices. After a few devices are added, you can disable it if you prefer. See the next section for details.

Approve Logins From Unknown devices

To set up approvals for unknown device Logins, you will first need to ensure you have registered a mobile phone with Facebook. Then go to the “Login Approvals” section in the Facebook Security, check the box and save. A code will be sent to your phone for verification.

If your current computer isn’t registered yet Facebook will ask you to give it a name. Facebook will also give you the option to install a code generator on your smart phone to approve logins that way. It’s not required that you do this – it’s just another option you can use.

It’s a good idea to open a browser on your smart phone or tablet straight away and get those smaller devices registered.

Get Notifications About Logins From Unknown Devices

It’s possible for you to get a notification whenever someone logs into your account from an unknown device. This is a little less secure than the option requiring approval. In Facebook security, go to “Login Notifications” and check the box for email or text notifications as you wish to set this up. Note, you’ll need to give Facebook your phone number and authenticate it if you want text notifications. This is under Account Settings > Mobile.

What To Do If Someone Is Accessing Your Facebook Account

If you use these methods and see that someone is using your Facebook account, you can quickly view the active sessions and “End Activity” for anything suspicious. Then, immediately change your password for Facebook.

Good job, I never know that I have so many active sessions. thanks guy


Richard Borkovec

I’ve been using the “End Activity” for a while now, just to see how many places I’m actually still logged in at. It astounding how many times you can be logged in, and know it’s just you logged in, not someone trying to get into your account.

Angela Alcorn

Yeah, it can be creepy, hey?

Cant beat a bit of facebook security. Thanks

Thank you. Too much Facebook ‘hacking’ going on.



What if somebody hacks my facebook account or somehow gets my password and logs in on whatever device but remembers to log out afterwards. Would that login be seen in my active sessions or does this feature only list those devices on which one is still logged on?

Angela Alcorn

It will only show you the ones that are currently logged in. However, you can ask Facebook to notify you about logins from unexpected devices and also to ask for extra authentication from those devices. So, that would give you warning that something dodgy was going on and maybe even stop it from happening.

I cannot log into my account because without knowing it would cause all these problems i delted my phone number attached to my accound and all know recognized devices and deleted all history/cookies from my computer. I am beyond frustrated because no matter what i do i cannot log in. I am not receiving any code and i am not seeing anywhere to enter that code if i received one. What do i do? I am not making a new one, i want that old one because it has so much history on it. Please Help. Ps. i have sent numerous reports to facebook and i have recieved no responses.

When you try to log in on a new device it should send you the code, then also give an option along the lines of “Don’t have access to the code?”. From there you should be able to follow prompts to authenticate yourself in another way. I’m sorry I can’t help more than this as I’ve never found myself in that position.
