What Methods You Can Use?

Internet users recommend a lot of methods to secretly log into someone's Messenger, but not all of them work. While some are too complicated for ordinary users, others are just scams. Based on my own research, I found these methods to be useful.

1. Reset Password

If you can physically access the target user, you can cleverly reset their password and log into their Facebook account with the new password. 

Also, you might want to delete the password reset confirmation email so that they don't get to know your little act. Now that you know the password of the target user, you can use it to log into their Messenger online.


  • You need physical access to the device.
  • The target user might learn the whole thing at a later point.
  • The target user might get suspicious/notified when you log in from a different device.
  • If the target user logs out of their Messenger account from another device they own and try to log back into it they will see that their password changed. In this case, it is most likely that you will be the first suspect that comes to your kid's mind.

2. Read Messages Yourself

If you're trying to get into the Messenger of your kids, you can try to physically access their device and read their messages when they're not around or are asleep. You can also ask them for their phone to ‘check the weather' too!


  • The target user might get suspicious as they will notice that messages they have not read yet are marked as read.
  • You won't get enough time to read all the messages.
  • The target user might have deleted their chats.

3. Install a Keylogger

A keylogger tracks all the keys a target user types into their phone – and that includes their username and password. Installing a keylogger can help you get the credentials of your target user that you can later on use to log into Messenger online.


  • Again, you need physical access to the device
  • Keyloggers that actually work aren't free.
  • The target user might get suspicious/ notified when you log in from a different device.

4. Try Spy Apps

Keeping the best for the last, here's the solution that's guaranteed to work and has virtually no drawback other than being the costliest of all options.

Spy apps like eyeZy work silently and let you see everything the target user exchanges on their Facebook Messenger. Unlike keyloggers, you don't have to log into the target user's account, so they never get any notification and become suspicious. 

So if you are looking for a great monitoring and parental control solution for your kids' devices installing a spy app is probably the method you will have to resort to.


  • Spy apps are not free.
