It has become important to know that someone is using your WhatsApp account without permission without your permission. If you think a third person is misusing your WhatsApp, it is necessary to check immediately. With the measures below, you can find out in minutes whether your account is safe or not – and if there is an unauthorized login, how to close it:

How to check immediately – easy steps

Watch Linked devices
The first step is – Open WhatsApp app → Tap on “three dots” → linked devices (or “linked device”) in the right corner above.
Here the list of all those browser/device sessions will be seen which are currently connected to your account. If you do not recognize a session, tap on it and do “log out”.
See unknown changes in profiles and settings
If your name, photo, status etc. have suddenly changed – and you have not done this – it may be an indication that someone has reached the account.
Check the history of empty messages or strange messages
See if you have never sent a message to people, have “Hi” or links etc. This can also be a sign that someone is sending messages in your name.
One time password / verification code is being received
If you suddenly get the Whatsapp Verification Code (6 digits) SMS – while you have not login or registered – this is warning that someone is trying to login from your number. Never send the code to anyone in any such situation.
Two-step verification (two-step verification)
It gives additional protection layer. Go to Whatsapp → Settings → Account → Two‑step Verification → Enable (enable). In this way, next time the PIN set by you for login will be marked.
If there is doubt, do this work immediately

Log out from unknown sessions: Go to linked devices and log out of sessions you don’t recognize.

Change password/pin: If you are using two-step verification, change its pin.

Contact WhatsApp support: If you have not logged and the account is in use, then email WhatsApp and report.

Tell the people concerned: Send a message to the contacts that your account may be insecure, so that they do not open suspicious links or send money.

SIM Card Security: Talk to your mobile operator and ask if there is any unauthorized sim‑ swap attempt for your number.
