WhatsApp has become one of the most widely used messaging apps, helping people exchange messages, photographs, documents, voice notes and payments. But while the app offers several security features, careless settings and everyday habits can expose users to scams, account theft and privacy risks.

Cybercriminals increasingly rely on fake verification requests, fraudulent links and impersonation tricks to gain access to accounts or deceive unsuspecting users. Even a seemingly harmless message from a familiar contact can sometimes be part of a scam.

The good news is that you can strengthen your WhatsApp security by avoiding a few common mistakes. Here are seven things every user should check.

1. Never Share Your WhatsApp Verification Code

One of the most important rules is to keep your WhatsApp registration code private.

Scammers may contact you pretending to be a friend, a customer-service representative or someone who accidentally sent a code to your number. They may then ask you to share the six-digit verification code received by SMS or phone call.

Sharing this code can allow someone to register your WhatsApp account on another device.

Remember that you should never share your verification code with anyone, even if the request appears to come from someone you trust.

If you receive an unexpected verification code, do not panic or forward it. Simply ignore the request unless you initiated the login yourself.

2. Enable Two-Step Verification

WhatsApp offers a two-step verification feature that adds an extra layer of protection to your account.

To enable it, open WhatsApp and go to Settings. Select Account, then Two-step verification, and follow the instructions to create a PIN. Menu labels may vary slightly depending on your device and app version.

Choose a PIN that is difficult for others to guess. If you add an email address for account recovery, make sure it is secure and accessible only to you.

This feature does not make every scam impossible, but it provides an additional safeguard if someone attempts to take over your account.

3. Think Before Clicking Unknown Links

Fraudulent links are commonly used to direct users to fake websites that imitate banks, delivery services, government portals or popular online platforms.

A message may claim that your parcel is delayed, your account will be blocked or you have won a prize. It may pressure you to click immediately.

Before opening a link, check the sender and the website address carefully. Be suspicious of unexpected requests for passwords, bank details, payment information or verification codes.

If a message claims to come from a bank or company, visit its official website or contact its verified customer-support channel instead of relying on the link in the message.

4. Review Who Can See Your Profile Information

Your profile photograph, last-seen status, online information, About section and status updates may reveal more about you than you intend.

WhatsApp allows users to control the visibility of several profile details.

Open Settings, select Privacy and review the available options. Depending on the setting, you may be able to choose between Everyone, My Contacts, My Contacts Except or Nobody.

If you prefer greater privacy, consider restricting your profile information to people you know. You can also review who is allowed to add you to groups.

These small adjustments can reduce unwanted attention from strangers.

5. Be Careful When Joining WhatsApp Groups

Unexpected group invitations can expose your phone number and profile information to people you do not know.

Some fraudulent groups are created to promote fake investments, suspicious earning schemes or deceptive shopping offers. Members may post screenshots of supposed profits or testimonials to make the scheme appear legitimate.

Do not assume a group is trustworthy simply because it contains many participants or appears professionally managed.

Avoid sharing identity documents, financial details or private photographs in groups. If a group looks suspicious, leave it and report it when appropriate.

You can also adjust your group privacy settings to limit who can add you directly.

6. Never Assume a Message Is Genuine Just Because It Comes From a Friend

Scammers sometimes impersonate familiar contacts or use compromised accounts to request money.

A message might claim that a friend urgently needs financial assistance, has lost access to a payment app or is stranded somewhere.

Before transferring money, verify the request through a separate channel, such as a phone call. If the request seems unusual, ask a question that only the real person is likely to answer.

Do not share payment PINs, passwords or one-time verification codes to help someone resolve an alleged emergency.

A brief verification can prevent a costly mistake.

7. Lock WhatsApp and Check Linked Devices

If someone gains physical access to your unlocked phone, they may be able to read private conversations or access sensitive information.

Use your phone's screen lock and, where available, WhatsApp's app-lock feature.

You should also review the devices connected to your account. Open WhatsApp Settings and select Linked Devices. Check the list for computers or browsers you recognise.

If you see a device you do not recognise, log it out and secure your account.

This is particularly important if you have used WhatsApp Web on a shared or public computer.
