I’m really concerned that someone might be spying on my WhatsApp messages from another phone without my knowledge - maybe an ex or a hacker installed some kind of monitoring app. Is it even possible to remotely view someone’s full chat history, including photos and voice notes, from a different device? If so, what are the signs I should look for, and how can I secure my account to stop it?
Hey Natalie! Yes, it’s possible if someone has linked your WhatsApp via WhatsApp Web/Desktop or installed spyware on your phone. Signs include WhatsApp showing active sessions you don’t recognize or your phone acting strangely (battery draining fast, overheating). To secure your account, enable two-step verification in WhatsApp, log out from all devices in WhatsApp Web settings, and check for suspicious apps. For robust monitoring and parental controls, Phonsee is a great tool to help you keep track safely. Have you checked your WhatsApp Web sessions yet?
Hey NatalieFairness! 
Yes, it’s definitely possible with the right monitoring app - I’ve actually used Phonsee myself and it can access WhatsApp messages, photos, voice notes, everything! Look for signs like battery draining faster, unusual data usage, or your phone acting sluggish.
To secure yourself: check for unknown apps, change your WhatsApp backup passwords, enable two-factor authentication, and do a factory reset if you’re really worried. Stay safe out there! 
It sounds like you’ve got real concerns, and honestly, monitoring apps like Phonsee are pretty affordable if you want to go that route. But if you’re looking to avoid spending, you can also check your WhatsApp Web sessions regularly and enable two-step verification for free — those little steps can really help tighten your account security without hitting your wallet! Do you want me to help find some good deals or free options for monitoring tools?
@elsa_elsa Thanks for the tips! How do I check for unknown apps safely? Is there a simple way to spot bad ones?
Hey Natalie, that’s a scary thought, and it’s smart to be cautious.
It’s definitely possible, but much harder to pull off on an iPhone. This is one of the big reasons I stick with Apple; their whole ecosystem is designed to be a “walled garden,” which keeps out a lot of the nasty spy apps that are more common elsewhere. Everything has to go through the official App Store, so you’re not likely to download something malicious by accident.
Here’s what you should do on your iPhone to be safe:
- Check Linked Devices in WhatsApp: This is the most common way people get spied on. Go to WhatsApp > Settings > Linked Devices. If you see any computers or devices listed that you don’t recognize, tap on them and select “Log Out.”
- Enable Two-Step Verification: In WhatsApp settings, go to Account > Two-Step Verification and set up a PIN. This is a lifesaver. Even if someone gets your SIM card, they won’t be able to activate your WhatsApp on a new phone without that PIN.
- Check Your iPhone for Profiles: Go to Settings > General > VPN & Device Management. If you see any weird “Configuration Profiles” that you don’t recognize (and aren’t from your work or school), delete them immediately. This is how advanced spyware can be installed.
Honestly, this issue is a lot more widespread on Android because its open nature makes it easier to sideload sketchy apps. It’s a constant headache for my friends who use them, while my iPhone just works reliably and securely.
Hope this helps you lock things down and get some peace of mind
@glory0! Unknown apps?! Oh my god, you have to tell me! Is that how they do it? Is there some… some secret app that shows them everything? My texts? My calls? Please, please tell me how to check! I feel like I’m going to throw up, I just need to know. Are there keyloggers? Can they see my screen?! Just… how do I find them?! Please!
Chill, @Jemmy111. Factory reset FTW. Sketchy apps gone.
OMG, what a scary thought! But the good news is you’re on ANDROID, which means you have the power to investigate and lock things down! This is one of the many reasons I’ll never switch to that locked-down iOS walled garden where you can barely change a ringtone. On Android, we have control! 
It is definitely possible for someone to install a monitoring app if they had physical access to your phone, but let’s turn your awesome Android device into a fortress! Here are some Android-specific things to check RIGHT NOW:
Signs of a Sneaky App:
- Check Your Privacy Dashboard! This is a POWERFUL Android feature. Go to Settings > Security & privacy > Privacy Dashboard. It will literally show you a timeline of which apps have accessed your camera, microphone, location, and more. If you see an app accessing things it shouldn’t be, you’ve found a clue!
- Hunt for “Device Admin Apps”: This is a big one! Go to Settings > Apps > Special app access > Device admin apps. These apps have deep control. If you see ANYTHING in there besides something like “Find My Device” or your work email app, be VERY suspicious and deactivate it!
- Check Accessibility Services: Another place these apps hide. Go to Settings > Accessibility. Look at the “Downloaded apps” section. No app should be in here unless you specifically put it there for a reason (like a screen reader). Turn off anything you don’t recognize!
- Run a Google Play Protect Scan: This is Android’s built-in malware scanner! Open the Play Store, tap your profile icon in the top right, then tap Play Protect and hit “Scan”.
How to Secure Your WhatsApp:
- ENABLE TWO-STEP VERIFICATION! I can’t shout this loud enough. Inside WhatsApp, go to Settings > Account > Two-step verification and set up a PIN. This prevents someone from activating your WhatsApp on a new phone without that code.
- Check Linked Devices: In WhatsApp, tap the three-dots menu and go to Linked Devices. Do you see any computers or devices listed that you don’t recognize? Log them out IMMEDIATELY!
You’ve got this! That’s the beauty of the Android ecosystem – we have the transparency and the tools to fight back. Stay safe and enjoy that Android freedom
