4 Methods How to Log Into Someone’s Facebook Messenger Without Them Getting a Notification

Agnes W Linn

Suppose you’re wondering how to log into someone else’s Facebook without them knowing. In that case, we’re guessing you’re a parent with concerns about how your family uses social media, who’s on their friends list, and their conversations.

We don’t blame you. While Facebook is designed to help friends stay connected, there are too many groups and pages where complete strangers can interact. And that makes Facebook rife with opportunities for cyberbullying, harassment, and even conversations that could include drugs, sex, threats, and worse.

But there’s no need to worry. We’ll show you how to log into someone else’s Facebook without them knowing. We’ve got three methods to choose from. Find the one that works for you and use it to keep your loved ones safe.

Method #1: Get a Phone Monitoring App

If any of the simpler methods we’ll cover later in the article don’t work for you (and even if they do work), you should first and foremost consider a parental control app like mSpy.

It lets you access their Facebook, so you can scroll through and see what they’re up to on the social media app.

With the built-in screen recorder feature, you can see everything that’s happening on Facebook, even if you’re not friends with them on Facebook. And if you’re wondering what they’re chatting about, mSpy has you covered.

The mSpy monitoring app lets you see their private Facebook Messenger chats, so you won’t need a separate app to know how to access someone’s Facebook messages.

We know what you’re thinking. Can someone see if you log into their Facebook? With mSpy, you won’t have to worry. The monitoring app works in hidden mode, so they won’t know you’re checking out their Facebook. They won’t receive an alert on their phone, so they’ll never know you’re reading their timeline or chats.

Method #2: Reset Their Password

So, you want to know how to get into someone’s Facebook, but you’re not the most tech-savvy person. We get it, and that’s where the old password reset functionality comes in.

If you know the email address tied to their Facebook account, you can reset their password by going to the Facebook login page and clicking the Forgot Password link.

You’ll need access to their email account for this method to work. Assuming you do, just follow the message from Facebook to reset their password. Then log in using the new password.

Now that you understand how to log into someone’s Facebook, there’s one important thing to remember with this method. Even if you know their Facebook password, they’ll likely receive an alert on their phone when you try to log in. This alert isn’t necessarily a popup.

Instead, they’ll receive a message in the Notifications section: “An unrecognized device recently attempted to access your account. Let us know if it was you.” You won’t be able to log in to Facebook until the owner of the Facebook account confirms that it was them. And you may fail to bypass the Facebook login message.

Method #3: Use Their Phone Lock Password

This method may seem simple, but it works for those whose loved ones leave their phones lying around.

If you’re trying to figure out how to log into someone’s Facebook Messenger without them getting a notification, this method is pretty foolproof. That’s because as long as you know their phone password, you won’t need to know their Facebook login credentials.

When you unlock an iPhone or Android, you’ll have direct access to each app without having to log in to each one. That’s the way these phones are designed. Log in once, and you’re good to go. Can you log into someone’s Facebook without them knowing? With this method, absolutely.

Method #4: Access Their Account on Another Device

Accessing the account on another device can be done if the user has left their account logged in on a mobile device or computer you can access. Answer the question: “If I log into someone’s Facebook, will they know?” – it depends on the security measures they’ve put in place for their account.

Why? Because this method is only effective if the user has not enabled two-factor authentication. In this situation, they will be notified when someone tries logging in using their account.

Go Beyond Just Facebook Monitoring

With mSpy, you can do even more than just monitor their Facebook. mSpy supports many social media networks, like Instagram, Snapchat, WhatsApp, Kik, Line, Skype, and even Tinder.

You can also:

  • see their location on a map,
  • get alerted when they use controversial words or phrases in chats (like sex or drugs, for example),
  • receive notifications when they enter or exit a specific zone you’ve pre-set,
  • see their web history,
  • view their stored media files and more.

There’s even a built-in keylogger to show you everything they typed.

Bottom line? Whether you want to figure out how to log into someone else’s Facebook or you’re looking for other ways to keep them safe, mSpy is the Facebook monitoring app you didn’t know you needed. And it does way more than you think.

  • Hello good afternoon.
    I would like to know if the mSpy app needs to be installed on the target person’s iPhone?
    Or if you install it only on mine I can access it.

    • Hi, Ana! The app needs to be installed on the target device. You don’t have to install anything on your phone.

    • Hi, Vincent!
      We recently rolled out an update that allows you to monitor Facebook, Snapchat, Instagram, and WhatsApp without rooting the device, so no need for it anymore.

  • Hi,
    is there any other way to access somebody’s else Facebook account without having access to their devices but acting only from remote? Thanks.

  • Look on my Facebook login page and a few days ago a device logged in for my unknown place and I knew it wasn’t me so I got the device IP address and I don’t know who it is but I’ve got some information on the person or company but what I’m wondering is did I download an app that gave them access to my stuff? Because that’s the only thing I know it could be unless somebody put mspy on my phone. How can I find out if I have an app like that?

    • Hi, Patrick! I’m not sure the app would actually allow anyone to log in to your account from a different device. More likely, your login credentials were leaked somewhere. I’d suggest you check it via online data leak checkers, they usually work well. And you should change your password, obviously 🙂

    • Hi Willy!

      To install the software on the target’s phone, you must disable Play Protect on the device you want to monitor. This way, the target phone will not receive any notifications from the app.
