Rate this post

Are you afraid that someone will spy on your conversations on Facebook or, even worse, might steal your password and thus gain possession of your account on the social network? You are right to worry. Those related to privacy and cybersecurity are two issues with which we all must learn to have a certain confidence, and it is precisely for this reason that today I want to explain to you how to spy on conversations on Facebook .

No, don’t worry, I’m not crazy! I do not want to provide the bad guys with practical instructions on how to violate the conversations of the well-known social network (also because it is not as easy as some would have you believe). What I want to do is explain to you some techniques that the so called crackers, that is the “bad hackers”, are used to take to attack the devices of the victims and show you all the countermeasures that can be adopted to counter them. In short, if it is true that to counter the enemy you have to learn to know him well, I believe that this is the most constructive approach that you can have towards the danger of online espionage. That said, if you are ready to move on and have a few minutes to dedicate, make yourself comfortable and read on. Find all the information you need right below.

ATTENTION: spying on the conversations of others on Facebook is a serious violation of privacy, in some cases even a crime. This tutorial has been written for informational purposes only, it is absolutely not my intention to encourage illegal activities and therefore I do not take any responsibility for the use that may be made of the information presented below.

Password recovery from PC

When you logged into Facebook, your browser, that is the program you used to access the social network, asked you if you wanted to save your password? Well, know that if you answered affirmatively to that message, the Facebook password is stored in the browser settings and is easily accessible by anyone with physical access to the PC. To better understand what I am referring to – and possibly run for cover by deactivating the memorization of passwords -, follow the instructions below.


If you have accepted to save the Facebook password in Chrome , click on the button  (…)  located at the top right and select the Settings item  from the menu that appears. Now scroll down to the bottom of the tab that has opened, select the Show advanced settings item   and click on the Manage passwords link    to view the list of passwords stored in the browser. To delete the Facebook one, move the mouse cursor over it and press the “x” that appears on the side.

To completely disable the saving of passwords in Chrome, go to the Settings menu  , click on  Show advanced settings as just explained and remove the check mark from the item  Request to save your web passwords .

If you want, by connecting to the site , you can view and manage all the passwords that you have stored in Chrome and that have been synchronized on all your devices through the cloud services of the Mountain View giant.


Even Firefox allows you to store your passwords on your PC. To view the ones you have currently saved on yours, start the browser, click on the hamburger icon   located at the top right and select  Options  or  Preferences  from the menu that appears.

In the tab that opens, go to Security (in the left sidebar), click on the Saved logins button  (or Saved passwords ) and locate the Facebook password. At this point, if you want to delete access to the social network, select the item relating to the latter and press the Remove button . If, on the other hand, you want to completely disable the password saving function in Firefox, uncheck the option  Remember login data to sites .

If you want, you can also enable the Use a master password feature in Firefox’s security settings and have the browser prompt you for a password to view and use the passwords stored in it.

Microsoft Edge

To view the passwords you have saved in Microsoft Edge , start the browser, click on the button  (…) located at the top right and select the Settings item  from the bar that appears on the side. Then go to  View advanced settings , then to  Manage saved passwords  and locate the Facebook password and then delete it (by pressing the “x” on its right).

To completely disable Edge saving passwords, go back to the Settings> View advanced browser settings menu and move the lever relative to the Offer the ability to save passwords function to OFF .

Internet Explorer

Are you still using the old Internet Explorer ? You shouldn’t, it’s an outdated browser. In any case, I would like to point out that you can view (and manage) the passwords stored in the browser by starting the browser, clicking on the gear icon located at the top right and selecting Internet Options from the menu that appears.

In the window that opens, select the Content tab , press the Settings button for Autocomplete , then click Password Management and you will find yourself in front of the credentials management panel stored in Windows. Therefore, locate the entry relating to Facebook and delete it by clicking on it first and then on the Remove item that appears below.

To completely disable the saving of passwords in Internet Explorer, go to Internet Options> Content> Autocomplete and remove the check mark from the entry Username and password on the forms .


If you have a Mac and use Safari as your main browser, you can manage the passwords stored in the latter by going to the Safari> Preferences menu (top left) and selecting the Password tab from the window that opens.

At this point, you must type the password of your user account on macOS (the one you usually use to access the system) and, if you want to delete the Facebook password, you must select it and then click on the Remove button located at the bottom To the right.

If you want to completely disable the saving of passwords in Safari, remove the check mark from the Autofill usernames and passwords item .

How to save your Facebook password securely

If you want to keep the Facebook password on your PC, while avoiding that it can be discovered by the first who manages to put his hand on the computer, you can contact a password manager . If you have never heard of them, password managers are programs that allow you to keep passwords, credit card numbers and other sensitive information, protecting them in turn with a password. They are very simple to use, integrate with all major web browsers and synchronize access data on all devices: computers, smartphones, tablets, etc. There are both free and paid ones, I told you about them in more detail in my guide on how to manage passwords.

Password reset and theft

How to spy on Facebook conversations

I think I’ve told you at least a hundred times over the last few years, but to sleep reasonably soundly from the point of view of computer security, you need to use long, complex and different passwords for each website . Long and complex means consisting of at least 13-15 characters and including lowercase letters, uppercase letters, numbers and special characters (e.g. parentheses, exclamation points, asterisks, and so on). But passwords aren’t the only thing to choose carefully – other things that can seriously affect the security of an account are the security questions chosen for password reset.

If during the creation of your account you have chosen trivial security questions, or rather, trivial answers to security questions, you run the risk that an attacker, be it a “bad hacker” or a somewhat nosy acquaintance who wants to poke the nose in your business, can use this weapon to reset your account password (just visit this link and follow the instructions on the screen). The risk, fortunately, is quite limited by the fact that to take advantage of the security questions you need to have access to an e-mail box or a mobile number associated with the account, but it exists and must be taken into account.

Unfortunately the security questions cannot be changed after setting them for the first time (during account creation), so what I can recommend is to choose a strong password for your mailboxes (different from the one used for Facebook! ) and never leave your mobile phone unattended . And if you are not yet registered on Facebook and you have not yet set up some security questions for your account, I suggest you set “random” answers, ie answers completely disconnected from the question (therefore impossible to guess) and write them down in a safe place, for example one of the password managers I referred to earlier.

Another very serious risk is that which comes from phishing emails and scam messages sent via WhatsApp or other messaging services : these are fake emails from Facebook or alarming messages (eg. “If you do not access this Facebook page, it will become a payment “) that require changing your password or entering your account credentials. Well, know that Facebook never requests a password change via email and will never become paid . Never enter your login credentials on pages you have opened directly from email messages or messages on services such as WhatsApp.

To make your account even more secure, I recommend that you take these other steps.

  • Change your Facebook password – if your password is insecure and / or you suspect someone may have discovered it, change it. All you have to do is connect to this page of the social network and click on the Edit item in the Password field .

  • Check the accesses to your account – Facebook offers the possibility to control all active accesses on your account, that is to see from which computers, smartphones and tablets your account has been used and, if necessary, revoke the permissions to some of them. To view the list of accesses to your Facebook account, visit this page of the social network and click on the item Devices from which you are logged . If there is any unauthorized access among the accesses, deactivate it by clicking on the item End activity and immediately change the password of your account as I explained before.
  • Enable two-factor authentication– another piece of advice that I always give you in my posts dedicated to cyber security, and which also applies to Facebook, is to activate two-factor authentication. If you have never heard of it, two-factor authentication (also called two-step verification) is an additional security measure that allows you to associate your account password with a disposable code to be received via SMS or generated via app. This code will be requested every time you try to log in to Facebook from a new browser or a new device, and this makes it impossible for attackers to access even if they discover the primary password of the account (as they would have no way of seeing the disposable code delivered to the mobile phone of the legitimate owner of the account). To enable two-factor authentication, connect tothis page of the social network and click first on the entry Approval of access and then on the entry Allow which is located next to the Two-factor authentication option .

Spy apps

How to spy on Facebook conversations

As I was able to explain to you in numerous posts (for example the one on how to spy on a mobile phone), there are applications that, if installed on the smartphone, allow you to remotely monitor everything that happens on the latter. They are divided into two broad categories: the application for parental control and indicator applications. The former are mainly aimed at monitoring the activities of minors, have fairly limited functionality (hardly allow you to spy on conversations on Facebook or other messaging services) and are very simple to configure; the latter are much more dangerous and powerful: they allow you to memorize all the phrases, words and data typed on the smartphone keyboard, they are completely invisible and often also allow you to capture the conversations you have online.

Among the applications for parental control I point out Qustodio  ( Android / iOS ) and  Screen Time  ( Android / iOS ), which are among the most used in the world. They are available on the Android and iOS stores and can be tried for free. As already mentioned above, they allow you to remotely monitor the user’s activities and limit the use of applications, including Facebook, but fortunately they do not allow you to directly capture the messages that are exchanged online. Among the spy applications, however, iKeyMonitor deserves particular attention which is available for both Android and iPhone and allows you to secretly monitor both the user’s activities (therefore the apps used, the searches made online, etc.) and the conversations had online and the texts typed on the keyboard. Fortunately, it is not for everyone, you can try it for free for 3 days but then it costs $ 22.49 per month.

And on the computer? Unfortunately, there are also spy applications for PCs, and they are also quite easy to find. I am thinking above all of keyloggers, some of which are free, which allow you to record all the texts that are typed on the computer keyboard (including passwords and messages exchanged on Facebook).

How to defend yourself from spy applications

The installation of spy software, both on smartphones and on PCs, requires physical access to the victim’s device. This means that with a little attention, by adopting adequate security measures, it is possible to limit the risk of receiving attacks of this type. Here are some of the security measures that are most effective at this juncture.

  • Install good antivirus and good antimalware on your PC. This way you should be able to spot and block computer keyloggers before they take action. If you want to know which are the best free antiviruses and how to eliminate malware from your computer, consult the guides I have dedicated to these topics.
  • Use a secure unlock code on your smartphone / tablet . By using a secure unlock code you will prevent someone, even if they get hold of your smartphone (or tablet), from applying changes to the system and installing spy apps. If you don’t know how to set or change your smartphone’s unlock code, follow the instructions below.
    • Android – go to the Settings> Security> Screen lock> PIN menu  and type the unlock code you want to use on your smartphone twice consecutively. If your phone has a fingerprint sensor, you can set up fingerprint unlock by going to  Security> Fingerprint . Avoid unlocking by gestures (the drawing to be done on the screen) as it is much easier to “guess” for those around. 
    • iPhone – go to the Settings> Touch ID and code menu  , select the item relating to the  code  and type the code you want to use on your phone twice in a row. If you have an iPhone with a fingerprint sensor, you can set up fingerprint unlock by going to  Add a fingerprint .

  • Check for the presence of spy apps on your smartphone / tablet – as specified above, spy apps can make themselves completely invisible and escape the sight of the user (i.e. the person to be spied on). Fortunately, however, there are “tricks” that in some cases allow you to find them.
    • Android – if you have an Android smartphone or tablet, go to the Settings> Security> Device administrators menu and check if among the applications that have administrator permissions there are some that you have not personally authorized. Furthermore, if you have a device subjected to the unlock procedure via root, start the SuperSU / SuperUser application and find out if among the applications that have access to root permissions there are some “suspicious” ones.
    • iPhone – if you have an iPhone (or an iPad), go to the Settings menu > Profile and device management and find out if among the applications that have installed custom profiles (and therefore have advanced permissions) there are any suspicious ones. If you cannot see the “Profile and device management” menu, it means that there are no apps on your device that use this type of mechanism.
    • Android and iOS – some spy applications available for both Android and iOS can be “found” by entering special codes. Some of these codes are   localhost: 8888  and  localhost: 4444 to be typed in the browser (eg Safari on iOS and Chrome on Android) and * 12345 to be typed in the dialer instead (ie in the phone number dialing screen).

  • Install an anti-malware for Android and block apps from unknown sources – if you have an Android terminal, install a good anti-malware (there are also excellent ones in the free sector) and block the installation of applications from unknown sources, i.e. from sources other than the Play Store. If you don’t know how to do it, go to the Settings> Security menu and disable the Unknown sources option .

Sniffing of wireless networks

How to spy on Facebook conversations

Communications on Facebook and Facebook Messenger are not easy to intercept, if you use the “secret conversation” function they are even protected with end-to-end encryption like those of WhatsApp. However, it is better not to take unnecessary risks and not to expose yourself to threats such as sniffing wireless networks , i.e. the interception of data passing on wireless networks that can be implemented with solutions such as those I reported to you in my tutorials on how to hack WiFi and how to sniff a network. wireless.

To avoid – or at least minimize – the risk of sniffing wireless networks, you need to take two very important security measures.

  • You must not use public Wi-Fi networks , which are known to be the “hunting ground” of choice for bad guys.
  • You must adequately protect your Wi-Fi networks by setting a long and complex key (at least 13-15 characters, including lowercase, uppercase, numbers and special characters), using an advanced encryption system (eg. WPA2-AES ) and if possible, disabling WPS. For more information on this procedure, read my tutorial on how to set wireless network passwords.
