Other Popular Ways To Read Someone Else’s Facebook Messages

Although there are other mediums to know how to get into someone’s Facebook, spy applications rank #1 as they’re effective, efficient, and stealthy. 

However, you can try other DIY methods if you’re new to FB Messenger spying. 

Notable mentions include: 

Reset the Password

The benefit of this method, besides being free, is that you wouldn’t lock the person’s account, and if you did everything correctly, they wouldn’t be informed.

Here’s how to get started:

  1. Enter the email address associated with the questioned profile.
  2. Select the “Forgot My Password” tab.
  3. Enter a valid email address that you can access and is unrelated to the profile.
  4. Respond to the security queries.
  5. Reset passwords.

However, even if you’re successful with the password reset, the target will be aware of the intrusion, and you’ll need to reset the password if you want to check their conversations.

Brute Force Attack

A brute force attack is a technique for breaking codes. According to some estimates, 5% of security breaches were caused by brute force operations. 

In a brute force attack, usernames and passwords are guessed to access a system without authorization. 

Brute force is a straightforward assault strategy.

Using this alternative, you must determine your victim’s password. It might take several months to gain access using this strategy because password guessing isn’t an easy endeavor. 

Since Facebook will stop you after five wrong attempts, using this approach is counterintuitive. 

Facebook Hacking Websites

With Facebook hacking websites, one begins by typing the target’s Facebook account URL. 

The website now tricks the target into thinking that a hack is occurring on their profile by displaying specific information from Facebook’s Graph Search.

This information might include the target’s username, a large version of their profile photo, and the number of hacking attempts on their account.

The website notifies the attacker following a successful hack that they’ve created a personal account for them on the portal (equipped with a random username and password) and that they must log in to their accounts to access the target’s Facebook account information. 

This alternative could be a waste of time, as the Facebook Messenger login to another account doesn’t exactly work as intended. 

Fake Facebook Buttons

The “like” and “share” buttons on a phony website can lead you to a fake login page where your information will be stolen.

To avoid this, open a separate tab and log into your Facebook account. Don’t worry, your web browser will ensure you’re logged in on other tabs. 

Any likes or shares will be sent straight to Facebook.

You can deduce that the aforementioned options aren’t reliable as compared to using mSpy.


If You Log Into Someone’s Facebook Messenger, Will They Know? 

Most people ask questions like, “if you log into someone’s Facebook Messenger, will they know?” 

Yes, they will, asFacebook always sends an email or text message if someone signs in to an account from an unidentified computer or mobile device. 

With this, you can stop the process and change login details. 

However, with spying services like mSpy, a target can’t detect intrusion on their Facebook Messenger. 

So, with this explanation, can you log into someone’s Facebook messenger without them knowing? 

Yes, when you use mSpy.
