No, because of end-to-end encryption, no one (not even WhatsApp) can see your messages on another phone unless they physically access your primary phone, link their device (which you'd be notified about), or you share your verification code/PIN. If someone does link a device, you'll get alerts, and you can review and log them out in your linked devices settings to stop them.
So, to confirm if someone is reading your WhatsApp message from another device, please go to WhatsApp Settings > Linked devices. If there is an unknown device connected to your WhatsApp, remove it to stop unauthorized access.
Right after you link a device, your primary phone sends an end-to-end encrypted copy of your most recent message history to your newly linked device, where it's stored locally. It can take a few minutes for your message history to appear on linked devices depending on the number of messages in your chats.
Yes, someone can spy on your WhatsApp messages if they gain access to your device or account. This can happen through spyware apps, phishing attacks, stolen login credentials, or unauthorized WhatsApp Web sessions.
How to know if your WhatsApp is being monitored
Two ways hackers can hijack your WhatsApp account
Cybercriminals can take control of your WhatsApp account in one of two ways. They either add another device to your account using the “Linked devices” feature, or re-register your account on their device as if you'd bought a new phone.
Linked devices provide a reliable, secure way to access WhatsApp from any of your devices. You can stay connected by linking up to four devices at a time to your primary phone. You'll still need your primary phone to register your WhatsApp account and link new devices. Learn how to link a device here.

3. Review connected devices in Google Account (Android)
To link someone else's WhatsApp to your phone, you typically use the "Link a device" feature on your phone, scanning a QR code from their device, allowing you to use their account's chats on your phone (or computer/tablet), but this requires access to their phone and permission; otherwise, you can only add them as a contact or invite them via their number. The primary method involves opening WhatsApp settings on your phone, selecting "Linked Devices," tapping "Link a device," and then scanning the QR code that appears on the other person's phone when they open WhatsApp and choose to link a companion device.
You know someone read your WhatsApp message by looking at the checkmarks next to it: two gray checkmarks mean it's delivered, while two blue checkmarks mean they've opened and read it. In group chats, you can always see who've read your message by long-pressing the message and selecting "Info," even if personal read receipts are off.
You can tell if someone read your text through read receipts in apps like iMessage, Google Messages (RCS), or WhatsApp, which show "Read" with a timestamp when the recipient opens it, if both you and the other person have the feature enabled in your settings. For regular SMS, you'll only see "Delivered," but some apps offer delivery confirmations or you can infer from a quick reply.
You can now use the same WhatsApp account on multiple devices at the same time, using your primary phone to link up to four devices. You'll need to log in to WhatsApp on your primary phone every 14 days to keep linked devices connected to your WhatsApp account.
Unfamiliar devices logged in to your account
WhatsApp Web makes it easy to tell if someone has accessed your WhatsApp account. All you have to do is open WhatsApp on your phone, and go to Settings > Linked Devices. You will be able to see all the devices remotely accessing your account.
There are also apps that can access a smartphone remotely with just a phone number. Once connected, snoopers have access to the following infomration: Real-time GPS location, allowing Google Maps to obtain accurate details about the address. Text messages, including all the messages you sent and the ones you received.
Key Takeaways:
WhatsApp doesn't let you see who viewed your profile, but it shows Status viewers. It is better to strengthen our privacy settings rather than bother trying to track visitors. Almost no third-party profile viewer tracker apps work as advertised.
Once you've confirmed you have a Google Account backup, you can start the restoring process. If you don't have a Google Account backup, you can still restore chats on a new device by transferring chats from your old device.
WhatsApp offers more security than text messaging by using end-to-end encryption, which ensures only the sender and receiver can read the messages. But neither option is immune to smishing scams, designed to steal your personal information or get you to click malicious links.
You can switch your WhatsApp account to a new phone without receiving an SMS code. If your phone number is eligible, you can verify it using your old device. WhatsApp will send a push notification to the old device that will provide the 6-digit code to enter on your new device.
To check if there are other devices linked to your Android phone, launch your smartphone's Settings app. Depending on the brand or model, you may have to look for and tap “Linked devices” or “Connected devices.” Go through the list to ensure all items are familiar or yours.
