Open WhatsApp, go to Linked devices, and look at every device in the list. On Android, tap the three dots at the top right and choose Linked devices; on iPhone, open Settings and tap Linked devices. If you see a computer, tablet or browser you do not recognise, tap it and choose Log out.
Most people link WhatsApp to a laptop once, forget about it, and never look at that list again. That is exactly the gap that lets someone read your chats without ever knowing your password. Here is how to check, what to do if something looks wrong, and how to make it harder for anyone to link a device to your account in the first place.
What “linked devices” actually means
WhatsApp lets you use the same account on other devices, such as a PC, a tablet or a second phone, without keeping your main phone switched on all the time. Each of those is a “linked device”. As far as I can tell from current reporting, you can have up to four of them alongside your main phone.
That is convenient. It is also why the list matters: a linked device can show your chats, so a forgotten or unknown entry is something to take seriously.
How to check WhatsApp linked devices (Android and iPhone)
| Step | Android | iPhone |
|---|---|---|
| 1 | Open WhatsApp | Open WhatsApp |
| 2 | Tap the three dots at the top right | Tap Settings (bottom right) |
| 3 | Tap Linked devices | Tap Linked devices |
| 4 | Tap a device you don’t recognise | Tap a device you don’t recognise |
| 5 | Tap Log out | Tap Log out |
Each entry shows when it was last active. A laptop you used yesterday is fine. A device that was active at 3 a.m. last week, and that you do not own, is not.
After you log out, the entry may show “log out is pending” for a while. It disappears from the list once the other device next tries to use WhatsApp.
Signs someone else may be using your WhatsApp
- A device in the list that you do not recognise or no longer use.
- A device whose “last active” time does not match when you used it.
- Messages marked as read that you never opened.
- A WhatsApp message or call from a stranger asking you to enter a code or tap “link device”.
None of these proves your account is compromised on its own. But if two or more match, log out of everything and move to the steps below.
What to do if you find an unknown device
- Tap the unknown device and choose Log out. Repeat for every entry you do not recognise.
- Turn on two-step verification: go to Settings, then Account, then Two-step verification, and set a PIN you will remember. On Android you can also add an email address in case you forget the PIN.
- Turn on App lock under Privacy so that a stranger holding your unlocked phone cannot easily open WhatsApp.
- Change your phone lock to something strong, because linking a new device only needs a few seconds on an unlocked phone.
- Tell your contacts if you think messages may have been sent in your name.

The same habits that protect WhatsApp also protect your Google account; see how to create a passkey for your Google account and how to enable two-factor authentication on Google.
The code scam to watch for
A scam reported as “GhostPairing” works differently from a stolen password. The attacker sends a message that looks like it comes from a friend or from WhatsApp, and talks you into entering a pairing code or approving a device link. Once you do, the attacker’s device is linked to your account, and your password never came into it.
The rule is simple: never enter a pairing or verification code because someone messaged you asking for it, and never approve a device link you did not start yourself.
Habits that keep your list clean
- Check Linked devices once a month. It takes about 20 seconds.
- Log out of WhatsApp Web on shared, office or cafe computers every time.
- Keep WhatsApp updated from the Play Store or App Store.
- Use fingerprint or face unlock for the phone, not a simple pattern anyone can watch you draw.
Frequently asked questions
Can someone read my WhatsApp without my phone?
Yes, if their device is linked to your account. Linked devices keep working even when your main phone is offline, which is why unknown entries need to be removed quickly.
Will logging out of a linked device delete my chats?
No. Logging out only removes that device from your account. Your chats stay on your main phone.
How many devices can I link to one WhatsApp account?
Up to four linked devices, plus your main phone, according to current reports. If you hit the limit, log out of one you no longer use before adding another.
Does WhatsApp tell me when a new device is linked?
Do not rely on it. Notifications can be missed or turned off, so the Linked devices list itself is the only reliable place to check. Turning on push notifications for WhatsApp also helps.
I do not use WhatsApp Web. Do I still need to check?
Yes. Anyone who used your unlocked phone for a few seconds could have linked a device without you noticing. An empty list is the result you want.
