How to Tell If Someone Else Is Using Your Facebook Account

Social media giants like Facebook are not immune to security issues. If you have recently noticed some strange activity on your Facebook account, your account may be compromised.

Was it a picture you do not remember posting or a change you do not recognize in your feed? This article will show you how to tell if someone else is using your Facebook account.

Signs Your Facebook Account is Compromised

Before we dive into confirming that someone has used your account, let’s first review some account behaviors that indicate someone is in your Facebook account.

If you experience some of these issues, someone likely has access to your account:

• Changes were made to your contact email or password.
• Your birthday, name, or other profile details have changed.
• You are getting friend requests or accepting friend requests from people you do not know.
• Facebook Messenger shows communications that you did not send. Or, you’re receiving a lot of messages from people you do not know.
• Pictures, posts, or uploads appear that you did not initiate.

These account behaviors indicate that someone else is using your Facebook account. Of course, if you suspect that someone else is using your account, there are ways to confirm your suspicions.

How to See Log in Locations on Facebook

Before wracking your brain and thinking about what your new password should be and how much time you have to react, there’s another step to consider.

You can tell if someone else has used your Facebook account by checking the list of devices and locations where your account is being used. Facebook enabled this feature several years back to help monitor your logins and flag suspicious sessions.

Remember that Facebook won’t give you the precise location of each log-in or the identity of the interloper. Some location details might be way off; it all depends on where you are in the world and the server’s location. Regardless, you’ll still have the date and time stamps, as well as which device got used to gain access.

Facebook has a lot of settings. Often, it’s kind of difficult to navigate through all of them. How, for instance, are you supposed to find the Activity history on Facebook? Here’s how to do it.

Get Facebook History from iPhone or Android

Most people use Facebook on their phones, so here is how to check your login history using the Facebook app:

1. Open the Facebook app and tap the “Hamburger menu icon” in the top right corner. Android users will find this menu in the upper right-hand corner of their screens and iOS users will find it in the lower right-hand corner.
   
2. Scroll down under “Settings & Privacy,” then select “Settings.”
   
3. Under “Security,” select “Security and Login.” You will find yourself on the page with a section called “Where you’re logged in.” Facebook will show you the “Active now” status in blue letters. It should be the device you are currently using.
   
4. If you want to see more, tap on the blue “See all” option to the right. You’ll see the last active sessions, including the approximate location, type/model of the device, and the most recent log-in time.
   
5. If you see a device or location that you do not recognize, tap on the three vertical dots. Then, select “Log Out.”
   

You can also tap the “Secure Account” option on this page. This button will walk you through changing your password and other Facebook security features.

Get Facebook History from a PC or Mac

If you find navigating through the Facebook web portal more convenient than the app, you can check the log-in history using that method.

The overall concept is the same. Given that the website and the app have some significant differences regarding the user interface (UI,) it is best to list all of the steps required for the website. Here is what you need to do:

1. Log into your Facebook account, then click on the little “downward triangle” in the top right corner of the screen.
   
2. From the drop-down menu, select “Settings and Privacy,” then choose “Settings.”
   
3. From the panel on the left, select “Security and Login.”
   
4. You can also see the “Where You’re Logged In” option. The current active session is listed, and the green “Active now” status displays. If you want to see all sessions, click on the blue “See More” option, and the menu will expand.
   

That is all there is to viewing Facebook history from a PC or Mac.

How to Log Out of Devices in Facebook

Locating the suspicious device or activity might be easy enough, but what are you supposed to do once you learn that information?

You can check your last activity on Facebook using your phone, tablet, or computer with a few straightforward steps. The best course of action is to log out of the devices you do not recognize or log out from every device to be extra safe.

That is entirely up to you. Fortunately, unlike some social media platforms and websites, Facebook will give you both choices. Here is how you do it.

Log Out of a Certain Device in Facebook using iOS or Android

If you’d like to keep your current devices connected to Facebook, you can always log out of the unknown device with ease.

1. Launch Facebook on iOS or Android, then click the “Hamburger Menu icon” in the top-right section.
   
2. Select “Settings.”
   
3. Under the “Security” menu, tap on “Security and Login.”
   
4. Select “See all” to open the entire list of devices.
   
5. Tap the “ellipsis icon” (three vertical dots) to open the selected device’s activity details.
   
6. Select “Log Out” for the chosen device.
   

Performing these steps will instantly log the user out of your account. If it was someone accessing your account and you changed your login credentials, they won’t be able to log back into your account. If the device shows up again later, it might be one of your devices, even if it displays as an unknown device. However, it is still possible that a hacker could crack your new login password too.

Log Out of All Devices at Once in Facebook from iPhone or Android

If the only device you use to get online is your smartphone, or you prefer it, logging out from all devices on Facebook is the best route to go.

1. Open the Facebook app and navigate to “Menu -> Settings -> Security and Login -> See all.”
   
2. Scroll to the bottom and then select “LOG OUT OF ALL SESSIONS.”
   

Facebook automatically signs you out from all sessions on the list, except your current session.

Log Out of All Devices at Once in Facebook from a PC or Mac

You can log out of all sessions at once or individually by accessing the Facebook web portal. If you are worried about certain strange activities on your profile, you need to do the following on your Mac or PC:

1. Navigate to the “Where You’re Logged In” option. Click on the blue “See More” option to expand the list of all past and current sessions.
   
2. If you want to log out every device in one go, click on the “Log Out Of All Sessions” option in the bottom right corner.
   
3. Facebook will ask you to confirm your choice by clicking on “Log Out” again.
   

Log Out of Certain Device in Facebook using PC or Mac

If you feel that there is no need to log out from everywhere, there is a solution for that too. Here is how to log out of specific devices in Facebook using Windows or macOS:

1. Select the device or session you are not sure about and click on the “ellipsis” icon (three vertical dots) on the side. A tiny pop-up window will appear that says, “Not You?” and “Log Out.”
   
2. The “Not You?” option gives you a chance to review the session and perhaps remember that it was you after all. Alternatively, you can get a little more information about the activity.
   
3. The “Log Out” option will immediately log out the device in question.
   

You can repeat this process as many times as you need. Facebook won’t allow a sign-out from your current session on the web portal, just like Android and iOS.

Frequently Asked Questions

Protecting your Facebook account is of utmost importance. If you still have questions, keep reading.

Can I find out who logged into my Facebook account?

Unfortunately, these methods will only show you the device type, location, and IP address (if you hover over the login). Unless it is someone you know, you are not likely to find out exactly who is logging into your account.

What if someone took over my Facebook account?

If someone unlawfully gained access to your Facebook account and you can no longer log in, the first thing to do is contact Facebook support. If you still have access to the email on the account, do a password reset. Fortunately, we’ve already covered how to get your Facebook account back; this article should help if you can’t log into your account.

What is Facebook’s Trusted Contacts feature?

The Trusted Contacts feature allows your friends to help you get back into your account if you get locked out. Facebook will send your friend a verification code for you to use and regain access.

Can someone log back into my account after I log them out?

Yes. If the interloper has your username and password information, they can easily log back in. It’s for this reason, you should also change your password and enable Facebook’s Two-Factor Authentication feature.

Do keep in mind that 2FA will not keep someone out of your account if they’ve saved the browser or device they used to sign in. You’ll need to change your password and verify that all of your account information is up-to-date and accurate before your account is secure. We have an article here that will help you set up Two-Factor Authentication.

Why would someone want to use my Facebook account?

Facebook accounts are free and easy to set up. So, why would someone take a particular interest in yours? There are many reasons why someone might want to pretend to be you online, but the more plausible explanation is that someone is trying to scam your friends.

Most users have received suspicious messages from their friends on Facebook. Scammers prey on users’ trust to get people to click on external links and reveal sensitive information. If someone is using (or spoofing) your account, it’s best to make a Facebook post and let everyone know your account was compromised.

What do I do if I think I’ve been phished?

Phishing is a type of scam where the hacker asks for your private information or sends you a link that exposes your private data. You’ve probably received a weird attachment on Facebook Messenger from one of your friends. Unsuspecting users often click these links without realizing their friends’ account is hacked.

If you’ve opened one of these links, the best course of action is to change your Facebook login credentials. Then, use the methods above to monitor any strange or suspicious activity.
