How to Secure WhatsApp from Hackers
Introduction: In today’s digital age, security is paramount, especially when it comes to messaging platforms like WhatsApp. With millions of users worldwide, WhatsApp is a prime target for hackers.
Protecting your account from unauthorized access is crucial to keep your conversations safe. In this post, we’ll guide you through practical steps and settings to secure your WhatsApp from potential hackers
Why do you need to secure WhatsApp?
Hackers employ various methods to gain unauthorized access to WhatsApp accounts, which can lead to data theft, financial fraud, and identity misuse. Among these methods, social engineering attacks and phishing attacks are the most common and dangerous.
Social Engineering Attacks
Social engineering attacks involve manipulating individuals into revealing confidential information. On WhatsApp, hackers may pose as trusted contacts or organizations to trick you into sharing sensitive details like your OTP (One-Time Password) or security PIN.
For example:
- A hacker might impersonate a friend or family member, asking for a verification code sent to your phone.
- They could claim to be WhatsApp support and ask for your account credentials.
Why it’s dangerous:
- Hackers can gain full control of your account, access your conversations, and impersonate you to target others.
How to protect yourself:
- Never share verification codes or personal information, even with people you trust.
- Be cautious of urgent or suspicious messages that pressure you to act quickly.
Phishing Attacks
Phishing attacks involve tricking you into clicking on malicious links or downloading harmful attachments. These links often appear to be from legitimate sources, such as WhatsApp itself, but are designed to steal your login credentials or infect your device with malware.
For example:
- You may receive a link claiming to offer free WhatsApp features or promotions.
- Clicking on the link could lead to a fake login page that steals your credentials.
Why it’s dangerous:
- Hackers can steal sensitive data, access linked accounts, and spread malware.
- Your compromised account could be used to scam others in your contact list.
How to protect yourself:
- Avoid clicking on links from unknown sources or unexpected messages.
- Verify the authenticity of links and messages before interacting with them.

Use a Strong and Unique Password for Your Phone
Your phone is the gateway to your WhatsApp account. To prevent unauthorized access, always use a strong and unique password, PIN, or biometric security (fingerprint, face recognition) to lock your phone.

- Choose a PIN, password, or set up biometric authentication.
Essential Tips and Settings for WhatsApp
1. Enable Two-Step Verification

To Enable Two-Step Verification:
- Open WhatsApp.
- Tap Settings > Account > Two-step verification.
- Tap Enable and follow the prompts to set up your PIN.

These settings allow you to get notifications when the security code for a contact’s phone in an encrypted chat changes, helping you maintain awareness of any potential security issues.
- Open Settings.
- Tap Account > Security notifications.
- Turn on Show security notifications on this device.
3. To Enable Passkeys:
Passkeys offer a more secure way to authenticate and log in to accounts, replacing traditional passwords with device-based or biometric authentication methods.
- Open Settings.
- Tap Account > Passkeys.
- Manage your passkeys or authentication settings.
4. To Manage Email Address:
- Open Settings.
- Tap Account > Email Address.
- Update or manage your email address settings.
5. To Enable Biometric and Automatic Lock:
- Open Settings.
- Tap Privacy > App Lock > Biometric & Automatic Lock.
- Enable or manage biometric and automatic lock settings.
6. To Manage Calls:
- Open Settings.
- Tap Privacy > Calls > Silence Unknown Callers.
- Enable or disable the Silence Unknown Callers setting to automatically silence calls from unknown numbers.
7. To Enable Advanced Privacy Settings:
- Open Settings.
- Tap Privacy > Advanced.
- Enable or manage the following settings:
- Block unknown account message
- Protect IP address in Calls
- Disable link previews.
The Advanced settings under Privacy provide more granular control over your device’s security and privacy features.
1. Block Unknown Account Messages:
- This setting helps block messages from unknown or unverified accounts, preventing spam or unsolicited messages from reaching you. Enabling it ensures that only contacts or known numbers can send you messages, which can enhance your security and privacy.
2. Protect IP Address in Calls:
- Enabling this option protects your IP address during voice or video calls. It ensures that your actual IP address is not exposed to the other party, which adds a layer of privacy by preventing tracking or targeted attacks based on your IP.
3. Disable Link Previews:
- This setting disables the automatic generation of link previews when you receive a message with a link. By turning it off, you prevent the app from showing a preview of the link’s content (such as a website’s title, image, or description) in the chat. This can protect your privacy by preventing sensitive information from being displayed automatically.
8. Turn on Two-Step Verification for WhatsApp Web
If you use WhatsApp Web or the desktop app, ensure that two-step verification is enabled to prevent unauthorized access to your WhatsApp from your computer.
To Enable Two-Step Verification for WhatsApp Web:
- Open WhatsApp.
- Tap Settings > Linked Devices.
- Enable Two-step verification.

Review the permissions you’ve granted to WhatsApp to ensure the app doesn’t have access to unnecessary data that could compromise your privacy.
To Manage App Permissions:
- Open Phone Settings.
- Tap Apps > WhatsApp > Install unknown apps > Allow from this source (disable or Off )
- Review and adjust the permissions as needed.
10. Keep WhatsApp Updated
Hackers often exploit vulnerabilities in outdated software. Regularly updating WhatsApp ensures that you have the latest security features and patches.
To Update WhatsApp:
- Open the App Store (iOS) or Google Play Store (Android).
- Search for WhatsApp and tap Update if an update is available.
11. Be Careful with Public Wi-Fi
Using WhatsApp on public Wi-Fi can expose your account to hackers. Always use a VPN when connecting to unsecured Wi-Fi networks to protect your data from potential interception.
