How to Tell If Your WhatsApp Account Has Been Hacked and What to Do

 



WhatsApp accounts can become targets of scams and account takeover attempts. Criminals may try to steal your verification code, trick you into linking an unknown device, or impersonate you to contact friends and family.

If something unusual happens, acting quickly can help protect your account and your contacts.

Here are the main warning signs and the steps to take.

1. Signs Your WhatsApp Account May Be Compromised

Watch for unusual activity such as:

  • Messages you do not remember sending
  • Friends receiving strange requests from you
  • Unknown linked devices
  • Unexpected verification codes
  • Changes to your profile information
  • Being unexpectedly logged out
  • Someone asking you for your WhatsApp verification code

One sign alone may not prove your account was hacked, but unexplained activity should be investigated.

2. Never Share Your Verification Code

WhatsApp may send a registration code when a phone number is being registered.

Never give that code to another person.

A scammer may pretend to be:

  • A friend
  • WhatsApp support
  • A company representative
  • Someone who accidentally sent a code to your number

If you receive a code you did not request, do not share it.

f you already shared a verification code with a scammer, follow our emergency guide on what to do next.

3. Check Your Linked Devices

WhatsApp allows an account to be used on linked devices.

Review the devices connected to your account and look for anything you do not recognize.

WhatsApp's official Help Center explains how to review and manage linked devices connected to your account.

If you find an unfamiliar device, log it out.

This is particularly important if someone briefly had physical access to your unlocked phone or convinced you to scan an unfamiliar QR code.

4. If You Were Logged Out Unexpectedly

An unexpected logout can be a warning sign that someone is trying to register your number elsewhere.

Open the official WhatsApp app and follow its account-registration or recovery process.

WhatsApp also provides an official recovery guide for compromised accounts.

Never pay a stranger who claims they can “recover” your WhatsApp account.

5. Turn On Two-Step Verification

Enable WhatsApp's two-step verification feature if it is available for your account.

Choose a PIN that other people cannot easily guess.

Do not share the PIN with anyone.

Also make sure any recovery email associated with the feature belongs to you and remains secure.

6. Warn Your Contacts if Scam Messages Were Sent

If someone used your account to contact other people, warn your friends and family as soon as you regain control.

Tell them to ignore suspicious:

  • Requests for money
  • Verification-code requests
  • Emergency messages
  • Investment offers
  • Links
  • QR codes

This can help prevent one compromised account from creating more victims.

Social media accounts can be targeted in similar ways, so you may also want to review our Facebook hacked account recovery guide.

7. Secure Your Email and Phone Number

Your wider account security matters too.

Protect the email account associated with important services using a unique password and multi-factor authentication.

If your phone suddenly loses cellular service unexpectedly, contact your mobile carrier through an official channel. In some situations, unexpected loss of service can warrant checking whether there has been an unauthorized change involving your mobile account or SIM.

8. Watch for Fake WhatsApp Support

Be suspicious of anyone who unexpectedly contacts you claiming to be WhatsApp support and asks for:

  • Your password
  • Verification codes
  • Two-step verification PIN
  • Payment
  • Remote access to your device

Do not provide sensitive authentication information.

Use WhatsApp's official app and official Help Center when you need account assistance.

9. What If You Already Shared a Code?

Act immediately.

Try to regain control through the official WhatsApp app and follow the recovery instructions provided there.

Then:

  • Review linked devices
  • Enable or review two-step verification
  • Secure your email
  • Warn affected contacts
  • Watch for additional scam attempts

If you reused a compromised password on other services, change those passwords too.

Quick Safety Checklist

If you suspect a WhatsApp account problem:

  • Never share verification codes
  • Check linked devices
  • Remove unfamiliar devices
  • Enable two-step verification
  • Secure your email account
  • Warn contacts about scam messages
  • Ignore unofficial “account recovery” offers
  • Use only official WhatsApp recovery/support channels

Final Thoughts

WhatsApp account scams often succeed because attackers convince users to help them complete the takeover.

Treat verification codes, two-step verification PINs, and device-linking requests as sensitive security information.

If you notice an unknown linked device, unexpected logout, or messages you did not send, investigate quickly.

And if someone asks you to send them a WhatsApp verification code, do not share it.

Guide note: WhatsApp's security settings and recovery procedures can change. Always follow the current instructions shown in the official WhatsApp app or Help Center.
