WhatsApp has become an essential part of everyday communication. From personal conversations and family groups to work discussions and sharing documents, a huge amount of private information passes through the app every day.

While WhatsApp offers several security features, many users never check them. A few simple changes can make your account and conversations significantly safer.

Turn on two-step verification

Two-step verification is one of the most important security features available on WhatsApp.

It adds a PIN that is required when your phone number is registered with WhatsApp again. This can provide an additional layer of protection if someone attempts to take control of your account.

Go to Settings, Account and Two-step verification to check whether it is enabled.

Protect your account with a passkey

If your device supports passkeys, consider setting one up for WhatsApp.

Passkeys use your phone's existing security system, such as fingerprint recognition, Face ID or your device PIN, instead of relying entirely on traditional passwords.

This can make account recovery and authentication more secure and convenient.

Check linked devices regularly

You may use WhatsApp on your laptop, tablet or another device, but it's worth checking the list of connected devices occasionally.

Open WhatsApp Settings and select Linked Devices. If you notice a device you don't recognise, log it out immediately.

This simple check can help you spot unauthorised access before it becomes a bigger problem.

Silence calls from unknown numbers

Repeated calls from unknown numbers can be more than just annoying. Scammers may use unexpected calls to establish contact before attempting to manipulate the victim.

WhatsApp's "Silence Unknown Callers" feature can prevent calls from unfamiliar numbers from ringing on your phone while still displaying them in your call list.

Control who can add you to groups

Being randomly added to unfamiliar WhatsApp groups can expose you to spam, suspicious links and fraudulent offers.

Check your privacy settings and restrict who can add you to groups. Depending on your preference, you can limit this to your contacts.

This is particularly useful for reducing unwanted messages from people you don't know.

Think twice before opening unknown links

A message doesn't become trustworthy simply because it arrives from a familiar-looking account.

Be especially cautious about links promising prizes, refunds, investment opportunities, job offers or urgent account verification.

If a message asks you to enter your password, OTP, banking information or card details, stop and verify the request independently.

Keep WhatsApp updated

Security features and vulnerability fixes are regularly included in newer versions of WhatsApp.

Avoid using outdated or modified versions of the app downloaded from unofficial websites. Keep WhatsApp updated through your device's official app store.

Your biggest security tool is still common sense

WhatsApp's security features can reduce risks, but they can't prevent every scam. Never share OTPs, passwords or banking credentials with someone over WhatsApp, even if they claim to be a friend, bank employee or company representative.
