Published: May 28, 2026
WhatsApp is no longer just a messaging app. With over 2.7 billion users worldwide, it has become the primary communication tool for individuals, businesses, and even governments. From sharing family photos to discussing confidential work projects, WhatsApp carries some of our most sensitive information.
However, the digital world has a dark side. Every single day, thousands of users fall victim to WhatsApp scams — account hijacking, OTP frauds, fake job offers, and even SIM swap attacks. In India alone, reported WhatsApp-related cyber crime cases crossed 15,000 in 2024 – a 54% jump from the previous year.
The harsh truth? Most users never change their default privacy settings. In fact, a recent sample survey of 1,000 users found that 73% had never opened the WhatsApp Privacy menu even once. That means your profile photo, last seen, online status, and even your chat backups are more exposed than you think.
Must-Have WhatsApp Security Settings to Enable Today
WhatsApp offers powerful security features, but they are not all enabled by default. The three settings below are absolutely critical for protecting your account from hackers and unauthorised access.
Two-Step Verification (PIN Setup)
This is the single most important security feature on WhatsApp. Even if a hacker manages to clone your SIM card or steal your phone number, they cannot activate WhatsApp on their device without your 6-digit PIN.
Step-by-Step Guide:
- Open WhatsApp → Go to Settings → Account → Two-Step Verification
- Tap Enable
- Create a 6-digit PIN (avoid easy numbers like 123456 or your birth year)
- Add an email address for recovery in case you forget your PIN
Why this matters: SIM swap scams are rising rapidly. In this attack, a hacker tricks your mobile carrier into transferring your phone number to their SIM card. Without two-step verification, they can instantly log into your WhatsApp. With it, they are completely blocked. According to cybersecurity firms, enabling this one feature blocks over 99% of automated account takeover attempts.
Critical Note: The recovery email you add must also be secured with a strong password and its own two-factor authentication. If your email gets hacked, your WhatsApp recovery options become compromised.
Biometric Lock (Fingerprint / Face ID)
What happens when you hand your phone to a friend, your child, or a colleague? Even if your phone is unlocked, WhatsApp remains open to anyone who opens the app. Biometric lock solves this problem.
Setup Instructions:
- Settings → Privacy → Fingerprint Lock (Android) or Face ID Lock (iPhone)
- Toggle the feature ON
- Choose when the lock should activate: Immediately is the most secure option
Once enabled, anyone trying to open WhatsApp will be prompted for your fingerprint or face scan — even if your phone is already unlocked. Your private chats stay private. A lesser-known fact: this also prevents accidental pocket-dials and unauthorized access during phone repairs.
Email Address Linking
Many users do not realize that adding an email address to WhatsApp is actually a security feature. This email serves two important purposes:
- Account Recovery: If you lose your device or forget your two-step verification PIN, WhatsApp can send recovery instructions to this email.
- Security Alerts: WhatsApp will notify you via email if someone tries to log into your account from an unrecognized device.
How to add or update your email:
- Go to Settings → Account → Email Address → Add or edit your email.
Make sure this email account itself is secured with a strong password and two-factor authentication.
How to Keep Your Personal Chats and Media Private
We share extremely sensitive things on WhatsApp — medical reports, financial documents, intimate photos, and confidential conversations. The features below ensure that even if someone gains physical access to your phone, your private data remains protected.
Chat Lock & Hidden Chats
Chat Lock is a feature that takes a specific conversation and moves it into a separate, password-protected folder. Locked chats do not appear in your main chat list, and their notifications are hidden.
How to lock a chat:
- Long press on the chat you want to lock
- Tap More → Chat Lock
- Confirm with your fingerprint or face ID
Once locked, the conversation moves to a folder called “Locked Chats” which appears at the top of your chat list (just below the search bar). To view it, you must authenticate with biometrics again. One underrated benefit: even if someone grabs your phone while you are using it, they cannot swipe over to your locked chats.
Important limitation: Chat Lock does not hide the chat from WhatsApp web or desktop if you are already logged in there.
Disappearing Messages
This feature automatically deletes messages after a set period of time. You can choose between 24 hours, 7 days, or 90 days. It is perfect for temporary conversations — project discussions, OTP sharing, or any sensitive talk you do not want permanently stored.
How to enable:
Open the chat → Tap the contact name at the top
Tap Disappearing Messages → Select your preferred duration
What you need to know:
Disappearing messages work with end-to-end encryption, and WhatsApp does not store these messages on its servers. However, the person on the other end can still take a screenshot before the message disappears. The feature does not prevent screenshots. A useful tip: use the 24-hour option for daily work conversations and 90 days for ongoing projects.
View Once Media
This feature allows you to send a photo or video that disappears immediately after the recipient opens it once. It is designed for highly sensitive images that you do not want to remain in someone’s chat history.
How to send View Once media:
- Tap the attachment icon (camera) → Take a photo or select a video
- Before sending, tap the “1” icon (View Once)
- Send the media
Critical limitations you must know:
- The recipient can take a photo of their screen using another phone — you cannot prevent this
- Screenshots are blocked by WhatsApp, but external cameras cannot be controlled
- The recipient cannot forward, save, or share View Once media
- You will be notified if the recipient tries to take a screenshot (on supported devices)
Bottom line: Only use View Once for media you are comfortable with the other person seeing at least once. If you want absolute protection, do not send sensitive media digitally at all.
End-to-End Encrypted Backups
This is one of the most overlooked but most important privacy settings. Your WhatsApp chats are end-to-end encrypted — meaning WhatsApp and Meta cannot read them. However, your Google Drive or iCloud backups are NOT encrypted by default.
Without this setting, Google or Apple can access your chat backup if required by law or if their systems are breached. Many users are shocked to learn that their old chat backups may still exist on cloud servers even after deleting messages from their phone.
How to enable encrypted backups:
- Settings → Chats → Chat Backup → End-to-End Encrypted Backup
- Tap Enable and create either a password or a 64-digit encryption key
- Store this password/key somewhere safe. If you lose it, you cannot restore your backup
Once enabled, even Google and Apple cannot read your backup. Only you can restore it.

Managing Who Can See Your Profile and Information
Every time you use WhatsApp, your profile photo, about section, last seen, and online status are visible to everyone who has your number saved. You can — and should — control exactly who sees this information.
Profile Photo, About, and Status Privacy
Your profile photo can reveal your identity, your location, or even your family members. Your “About” section (bio) can give away personal details. Your Status (WhatsApp Stories) can show your daily activities.
How to change these settings:
- Settings → Privacy → Profile Photo
- Choose from: Everyone | My Contacts | Nobody
Best practice: Use “My Contacts Except…” — this allows you to block specific people while still showing your profile to trusted contacts. For example, you might want all your contacts to see your photo except your ex-partner or a nosy coworker.
The exact same settings are available separately for About and Status under the Privacy menu.
Last Seen and Online Status
“Last seen 5 minutes ago” creates unnecessary pressure to reply immediately. Worse, stalkers can track your activity patterns — when you wake up, when you go to sleep, and when you are online late at night. Many victims of online harassment report that their last seen was used to monitor their daily routine before any direct contact was made.
How to hide Last Seen:
- Settings → Privacy → Last Seen & Online
- Select: My Contacts (only saved numbers) or Nobody
The trade-off: If you hide your own Last Seen, you also lose the ability to see anyone else’s Last Seen. This is WhatsApp’s fair-play rule. Your online status (the green dot) will also be hidden from people outside your selected group.
Read Receipts (Blue Ticks)
Blue ticks tell the sender that you have read their message. Disabling them removes this pressure.
How to disable:
- Settings → Privacy → Read Receipts → Toggle OFF
Pros: No one knows if you have read their message. You can reply on your own time without guilt.
Cons: You also lose the ability to see read receipts from others. In group chats, read receipts cannot be disabled — they always work.
Protection Against Unknown Callers and Scams
In the past two years, WhatsApp has seen an explosion of spam calls from international numbers (Ethiopia, Kenya, Vietnam, Malaysia, etc.). These scammers often ring once and hang up, hoping you will call back — triggering high international call charges. Others try to trick you into crypto scams or fake investment schemes. Some users report receiving 5-6 such calls per day at peak times.
Silence Unknown Callers
This feature automatically mutes calls from numbers not saved in your contacts. The phone does not ring, and you are not disturbed. The call still appears in your call log as a missed call, but you can ignore it at your convenience.
How to enable:
- Settings → Privacy → Calls → Silence Unknown Callers → Toggle ON
This single setting eliminates roughly 90% of spam and scam calls on WhatsApp, according to user testing across multiple regions.
Protect IP Address in Calls
When you make a voice or video call on WhatsApp, the default connection is peer-to-peer — meaning your IP address and the recipient’s IP address are visible to each other. A technically skilled attacker could potentially use this to estimate your geographic location.
WhatsApp’s advanced privacy feature routes your calls through WhatsApp’s relay servers, hiding both participants’ IP addresses.
How to enable:
- Settings → Privacy → Advanced → Protect IP Address in Calls → Toggle ON
Small trade-off: Call audio and video quality may decrease very slightly because the data travels through an extra server. For most users, the privacy benefit far outweighs this minor quality difference.
Group Invitation Settings
Few things are more annoying than being added to random groups — real estate promotions, lottery scams, religious broadcasts, or spam. This setting prevents strangers from adding you to groups without your permission.
How to configure:
- Settings → Privacy → Groups → Select “My Contacts Except…”
With this setting, only people already in your contact list can add you directly to a group. Anyone else must send you an invitation link. You can choose to accept or ignore the invitation.
Staying Safe from Common WhatsApp Scams
Despite WhatsApp’s strong security features, user behavior remains the weakest link. Below are the three most common scams currently circulating — and exactly how to avoid them.
OTP Scam (One-Time Password Fraud)
How it works: You receive a message from a “friend” or “customer care executive” asking for your WhatsApp verification OTP. The moment you share it, the scammer logs into your account, changes your two-step verification, and locks you out. They then message your contacts pretending to be you, asking for money or personal information.
A real pattern observed: Scammers often hack one account, then message everyone on that contact list using the same trick. This is why one compromised account can lead to dozens within hours.
How to avoid: Never share your OTP with anyone — ever. WhatsApp will never ask you for your OTP. No legitimate company will either. If someone asks for your OTP, they are 100% a scammer.
Fake Lottery / Job Offer Scam
How it works: You receive a message like: “Congratulations! You have won ₹5,00,000. Click this link to claim your prize.” Or “Work from home job. Earn ₹5,000 daily. Limited seats. Click here to register.” The link leads to a phishing website designed to steal your personal information or install malware on your phone.
How to avoid: Never click links from unknown senders. No legitimate lottery, government agency, or company will contact you via WhatsApp to announce a prize. If an offer sounds too good to be true, it is always a scam.
WhatsApp Gold / Fake Update Scam
How it works: This old scam still tricks thousands of users. You receive a message claiming that “WhatsApp Gold” — a premium, private version of WhatsApp — is available for free. The message includes a download link. Clicking the link installs malware on your phone that can steal your data, track your activity, or even take control of your device.
How to avoid: Only download WhatsApp updates from the official Google Play Store or Apple App Store. WhatsApp has no “Gold” version. Any message asking you to download WhatsApp from a link is a scam.
The Golden Rule of WhatsApp Safety: If something promises free money, easy jobs, or exclusive features — it is almost certainly a scam. Legitimate opportunities do not arrive via random WhatsApp messages.
You have now learned about almost every important privacy and security setting WhatsApp offers — from two-step verification and chat lock to scam prevention and encrypted backups. The truth is that no digital platform offers 100% privacy, but by applying the settings in this guide, you can reduce your risk by over 95%.
Do not wait until something goes wrong. Take 10 minutes right now to go through your WhatsApp settings and enable the features discussed here. Most people only think about privacy after they have already been hacked or scammed. Be smarter. Be proactive.
Your digital privacy is your responsibility. WhatsApp gives you the tools. The rest is up to you.
FAQ
Q1: Can someone read my WhatsApp messages if I have end-to-end encryption enabled?
A: No. End-to-end encryption means that only you and the recipient can read your messages. Not WhatsApp, not Meta, not any government or third party. However, if your phone is physically unlocked and in someone else’s hands, or if your chat backups are not encrypted, those messages could be accessed.
Q2: What should I do if my WhatsApp account gets hacked?
A: Follow these steps immediately:
- If you still have access, go to Settings → Linked Devices and remove any unrecognized devices.
- If you are locked out, uninstall WhatsApp, reinstall it, and attempt recovery using your two-step verification PIN or registered email.
- Contact your mobile carrier to ensure no SIM swap has occurred on your number.
- Inform all your contacts that your account was compromised so they do not fall for any scam messages sent from your number.
Q3: Does WhatsApp store my deleted messages?
A: Once you delete a message for everyone, it is removed from WhatsApp’s servers and cannot be recovered. However, the recipient may have taken a screenshot or backup before deletion. Disappearing messages also do not guarantee deletion from third-party backup services like Google Drive or iCloud unless you have enabled encrypted backups.
Q4: Can police or government read my WhatsApp messages?
A: With end-to-end encryption enabled and encrypted backups configured, not even WhatsApp can read your messages. However, law enforcement can legally access messages that are already on your phone (if they seize your unlocked device) or messages that the recipient has saved or shared.
