To hack someone’s Facebook messages is the password reset. It is the easiest way if you are a friend or relative of the target person whose Facebook account you are going to track.
Enter the legitimate e-mail of the target Facebook account, click the button “Forgot password?”. Press the button “No longer have access to this email?” when the system asks you about resetting. Type a new e-mail address that was not used for another Facebook account and answer a question that was set by the target user. You need to be close to the person whose Facebook messages you hack.
I'd say phone tracking apps would help a lot; you could use them to hack Facebook messages, see posts, pictures etc.
You can get these apps very easily and they are easy to use as well. Most of the apps ensure and guarantee your confidentiality. The best part of it is, you can do your spying remotely without having a physical access to the phone you are targeting. The apps run in stealth mode and hence the spying won't be noticed at all.
You could get one of these apps by visiting the official website of the provider, downloading the installation file and installing the software. You need to sign up and then use it following the instructions.
Spying on Facebook sometimes is a necessity. It becomes important when parents want to keep track of what their kids are doing on Facebook. It becomes necessary when employers want to monitor the activities of their employees while at work.
There are different ways to do it. The easiest methods, I'd say, are by trying the 'reset password' option and by using spyware apps. The 'reset password' option, as Susan says, is easy if you're close to the person whose account you want to hack. As for the spyware apps, you can buy them online and use them as per instructions to hack accounts, read messages and see photos.
