Is Someone Reading Your Messages? | AppMsr

How Others Usually See Your Chats

Messages appear on every device where your account is logged in. A forgotten laptop, a shared tablet, an old phone or a browser where you saved your password can keep showing new chats. Someone who has your password or an unlocked phone can also read them.

Code request scam

Never share a Messenger or Facebook login code with anyone

A login code sent to you is meant only for you. If a message asks for it, even from a friend, the sender's account may be stolen. Sharing the code can give them your account.

This code was sent to your number. Enter it only in your own WhatsApp app. Not you?

Never share this code

Restore

Restore your own chat history with a PIN

On a new device, restore end-to-end encrypted chats with your secure storage PIN, a one-time code or another method you set up earlier. Menu names may vary by app version.

Message: Your Messenger is being read by someone. Click here and log in to see who is watching you.

This is phishing. Messenger shows logged-in devices in Accounts Center, not on an outside link. Never log in from a link like this. 10:22

Good to know. I'll check Where you're logged in instead. 10:23

Review sent messages

Look for messages you didn't send yourself

Messages or links you didn't send are a strong sign someone else used your account. Warn the people who got them, log out unknown sessions, change your password and turn on two-factor authentication. If you can't log in, go to facebook.com/hacked from a trusted device.

Check account changes

Confirm your email, phone and name

Someone who takes over an account often changes the email, phone number or password so the owner can't get back in. In Accounts Center, check your personal details and contact info. If something changed without you, secure the account right away and use the official recovery steps at facebook.com/hacked.

Check Sessions

Where You're In

In Accounts Center, open Password and security and then Where you're logged in. Each entry shows a device, an approximate location and the time of last activity. Locations come from IP addresses and can be rough, so focus on devices and times you don't recognize. Menu names may vary by app version.

Log Out & Lock

Select any unfamiliar session and log it out, or log out of all sessions except the one you're using. Then change your password and turn on two-factor authentication so the same person cannot simply sign back in. Check your email and phone in Accounts Center to make sure they are still yours.

What Can and Can't Expose Chats

Logged-in Devices

Any device still signed in to your account shows your chats. This is the most common cause, and Where you're logged in lets you end it.

Shared Passwords

If you ever gave out your password or used it on another site, assume it is known. Change it, use a unique one and add two-factor authentication.

Unlocked Phones

Someone with your unlocked phone can open Messenger. Use a screen lock and turn on app lock if your phone or Messenger version supports it.

Not a Phone Number

Nobody can open your chats just by knowing your phone number or profile link. Sites that claim this are scams, not real tools.

Tips to Keep Your Chats Private

Old devices

Log out of phones and computers you no longer use

Before you sell, give away or recycle a phone or laptop, log out of Messenger and Facebook on it. If it's already gone, log that session out from Where you're logged in in Accounts Center.
Encrypted chats

Set a secure storage PIN so your chat history stays protected

End-to-end encrypted chats can be restored on a new device with your PIN or another restore method. Choose one you can remember, and don't share it.
Work accounts

Keep business and personal logins separate

If a team manages a Page, give each person their own access instead of sharing one personal password. When someone leaves, remove their access and review your sessions.
Notifications

Hide message previews on your lock screen

Message previews can show chat content to anyone near your phone. In your phone's notification settings, choose to hide previews on the lock screen for Messenger.
