Someone Linked My WhatsApp Web: How to Spot and End It
No malware, no password theft. Someone with 60 seconds of physical access to your unlocked phone scans a code, and your chats mirror to their browser. Here's how to see every linked device on YOUR account and cut off the ones you don't recognize.
Check my linked devices nowNo password, ever
Managing linked devices happens inside your own app — we never ask for your PIN or login.
Owner-only actions
Everything here secures the account you own; nothing links to a third party's WhatsApp.
Official Meta tools only
Linked Devices and app lock are built-in WhatsApp features — no add-ons, no scripts.
You can verify every step yourself directly in WhatsApp's Settings — nothing here requires our involvement to work.
How it works
- 1Open Linked DevicesWhatsApp > Settings > Linked Devices shows every browser and desktop mirroring your chats.
- 2Review each sessionMatch every entry to a browser or computer you actually use.
- 3Log out the unknown oneTap the unrecognized session and choose Log Out to end it instantly.
- 4Log out everything, to be sureUse 'Log out from all devices' so no linked session survives, even one you missed.
- 5Close the door behind youTurn on a phone screen lock and WhatsApp's app lock so a linking QR can't be scanned again.
There's no countdown here — a linked session stays active until someone ends it, which is exactly why checking this list regularly matters.
An unknown session is linked
- New incoming chats mirror to a browser you never opened
- Linked Devices shows a platform or last-active time you can't place
- Read receipts sometimes flip to 'read' before you've seen a message
- Your phone unlocks without a passcode, so anyone can scan the QR
Your account is owner-only again
- Linked Devices lists only browsers and computers you use
- You logged out of all devices and re-linked just your own
- App lock plus a screen passcode block any silent re-link
- You know to re-check the list after anyone borrows your phone
Ending a session is instant and reversible — but it only stays clean while your unlocked phone stays out of the wrong hands.
Unrecognized linked device
A session on a platform (Chrome, Edge, Mac, Windows) you don't use, or one you never set up.
Odd last-active time
'Last active' stamps at hours you weren't near a computer.
Silent link notification
WhatsApp shows a banner when a new device links — a link you didn't make is a red flag.
Premature read receipts
Messages marked read before you opened them can mean a second session is viewing.
No barrier to linking
If your phone has no lock and WhatsApp has no app lock, anyone can scan a QR in seconds.
Every check here is on your own account and inside your own settings. This never links you to anyone else's WhatsApp — WhaSpy does not help access, read, or track another person's account.
FAQ
Someone linked my WhatsApp Web — can I see who they are?
No, and be wary of any tool that promises this. WhatsApp shows the device platform and last-active time, not a name or identity. What you can do is end the session immediately with 'Log out', then log out of all devices to be certain. We can't reveal an intruder's identity and won't claim to.
How did a session get linked without my password?
WhatsApp Web doesn't use a password — it uses a QR code. Anyone with brief physical access to your unlocked phone can open the camera, scan a linking code, and mirror your chats. That's why this is the most common real 'spying' method, and why a screen lock plus app lock is the actual fix.
If I log out of all devices, do I lose my chats?
No. Logging out only ends the mirrored browser and desktop sessions. Your messages stay on your phone. You simply re-link the computers you actually use by scanning a fresh QR from your own WhatsApp.
Can someone read my WhatsApp remotely without linking a device?
The realistic vectors involve access to your phone or a linked session — not remote magic. For a fuller picture of what is and isn't possible, see our page on whether WhatsApp can be read without your phone. We never guarantee a phone is 'clean' or promise total anonymity.
How often should I check Linked Devices?
Any time someone has borrowed or had access to your unlocked phone, and as a periodic habit. There's no expiry on a linked session, so a check-in every few weeks — plus after repairs, lending, or a lost-and-found phone — keeps the list honest.
