How Find out if someone's logging in to your Facebook account || if someone unauthorized is accessing your profile

 

 

Suppose you used your facebook account at a public place ( like CYBER CAFE , FRIENDS LAPTOP etc. ) and you forget to log it out or sameone got your fb credentials using any keylogger software and used it for there fun by performing any kind of activity via your fb account and then you've noticed that activity suspicious on your Facebook account--messages you never sent, Wall posts you never published, or Notifications you never checked.

  

Luckily, Facebook recognizes this possibility and has implemented some security tools to ease your worries and help you keep track of any mischief on your account.( Whenever you, or anyone, logs into your Facebook account, a new entry is added to your login history: it includes the web browser or device / mobile app used, the estimated physical location, and the exact date and time. Since this setting is enabled by default (it cannot be disabled),
and since it cannot be bypassed in any way, it's a reliable method to noticing if someone unauthorized is accessing your profile. You can check the last time someone logged into your Facebook account at any time. Combined with the optional login notifications and login approvals (more on that below), it makes it impossible to hack into your account without your knowledge!)

To get started, head to Account Settings > Security. Then consider the following security options:

Here is how to enable Login Notifications and Login Approvals:

1. Click on the "triangle" drop-down menu in the upper right portion of the Facebook page.
2. Select "Account Settings". A new page will open.
3. On the upper left portion of the Facebook page you will see a tab called "Security" with a gold badge icon next to it. Click on it.
4. A list of security settings are presented. Look for "Login Notifications" and click on it.
5. Select the methods by which you will be notified when your account logs into Facebook (email and text message) and click the "Save Changes" button.
6. Immediately below the "Login Notifications" section there is the "Login Approvals" section. Select it.
7. Click on the checkbox to enable Login Approvals. A small window will open which explains what Login Approvals are and how they work. Click on the "Set Up Now" button to configure Login Approvals. A text message will be sent to your registered cell phone. Enter the confirmation code and click "Submit Code". Another small window will open with some additional information. Click "Close"

   

   
   

   Login Notifications and Approvals are now enabled.

To keep tabs on who is logging in, enable Login Notifications. Each time someone logs in to your account at an unrecognized computer or mobile device, Facebook will alert you via text message or e-mail. With that information, you can end that session (see No. 2) and change your password

 2. End any suspicious activity

  

1. Click on the "triangle" drop-down menu in the upper right portion of the Facebook page.
2. Select "Account Settings". A new page will open.
3. On the upper left portion of the Facebook page you will see a tab called "Security" with a gold badge icon next to it. Click on it.
4.  A list of security settings are presented. Look for"Where You're Logged In" and click on it
   

To see where exactly your account is logged in, head to "Active Sessions." You'll see your current session listed at the top, and log-ins on other computers below. If any of those log-ins look suspicious (you can usually tell by the location), click "End Activity" and change your password

 Important: If you don't recognize portions of your login activity, 

  immediately go change your Facebook password.
 If someone (a hacker, presumably) already did it, go through the 
password-reset process as soon as you can, to regain access to your 
account before it's too late!
