8 Essential WhatsApp Settings to Block Hackers Instantly

With nearly 3 billion users, WhatsApp has become more than a messaging platform, it's your social life, career, and private world in one app. But with that scale comes risk. Hackers, scammers, and spyware developers are increasingly targeting WhatsApp users with phishing, impersonation, and malware tactics.

This guide breaks down 8 powerful privacy settings and methods from two-step verification (2FA) to chat encryption that will help you protect your data and stay ahead of cyber threats.

1. Enable Two-Step Verification (2FA)

What it is:
Adds a second layer of security to your WhatsApp account using a 6-digit PIN.

Why it matters:
Without 2FA, hackers who trick you into revealing SMS codes can hijack your account. With 2FA, they’re locked out—even with your number.

How to turn it on:

• Go to Settings → Account → Two-step verification → Enable

• Set your 6-digit PIN

• Add a recovery email (optional but recommended)

This is your first line of defense. Turn it on now.

2. Adjust Privacy Settings for Your Profile

What to change:

• Last Seen & Online: My Contacts / Nobody

• Profile Photo: My Contacts

• About: My Contacts

• Status: My Contacts Except…

Why it matters:
Scammers use your public info for impersonation or to track your behavior. The less they see, the safer you are.

Stop oversharing by default. Control what strangers can access.

3. Block Random Group Invites

The problem:
Anyone can add you to groups including scam rings pushing fake crypto schemes, spam, or misinformation.

Fix it:

• Go to Settings → Privacy → Groups

• Set to My Contacts or My Contacts Except…

Why it matters:
Being added to unknown groups exposes your number to strangers. It's a top vector for phishing and spam.

You decide who adds you—not spammers.

4. Turn On Security Notifications

What it does:
Alerts you when your contact’s encryption code changes (e.g. they reinstall WhatsApp or switch devices).

Why it matters:
Unexpected changes could indicate a compromised device.

How to enable it:

• Settings → Privacy → Security → Show Security Notifications → ON

These small alerts can prevent big breaches.

5. Lock WhatsApp with Fingerprint or Face ID

Why it's important:
Even if someone unlocks your phone, your WhatsApp stays locked.

How to activate:

• Android: Settings → Privacy → Fingerprint Lock

• iPhone: Settings → Privacy → Screen Lock

This adds another wall of protection—and feels futuristic too.

6. Use Disappearing Messages and View-Once Media

What it does:
Auto-deletes messages after a set time. View-once photos/videos vanish after opening.

How to use it:

• In any chat → Tap contact name → Disappearing Messages → Choose duration

• Before sending a photo/video → Tap “1” icon for View Once

Why it matters:
Minimizes sensitive data lingering in your chat history.

Perfect for sharing personal info, one-time links, or anything confidential.

7. Encrypt Your WhatsApp Chat Backups

What’s at risk:
Backups stored on Google Drive or iCloud aren't encrypted by default. If someone accesses your cloud account, your chats are exposed.

How to encrypt:

• Settings → Chats → Chat Backup → End-to-end Encrypted Backup → Turn On

• Create a password or use a 64-digit key

Lose the password? You lose the backup. Store it safely.

8. Protect Yourself from Spyware

Spyware attacks, like Pegasus, have targeted WhatsApp users in the past—even through missed calls. While patches are released, threats evolve.

Stay safe with these steps:

• Always update WhatsApp and your phone’s OS

• Only download from official app stores

• Never click on suspicious links or unknown numbers

• Block calls from strange country codes

• Limit app permissions

• Use a trusted security app to scan your device

• Watch for signs: fast battery drain, overheating, high data usage

If needed, factory reset your phone but avoid restoring potentially infected backups.

Spyware is silent but dangerous. Awareness is your weapon.
