WhatsApp has established itself as the world's most popular instant messaging app , facilitating communication between millions of users daily. However, its popularity also makes it an attractive target for hackers and cybercriminals, putting your privacy, personal data, and even your digital identity at risk. Today, we'll tell you how to secure your WhatsApp account, protecting all your data and information.
Fortunately, there are measures and settings you can implement to turn your WhatsApp account into a true fortress . From privacy settings to advanced protections like two-step verification, all these mechanisms are at your disposal to prevent theft, impersonation, or unauthorized access.
Reasons why you should protect your WhatsApp account
Protect your WhatsApp account It's not just a matter of fashion. It is a real need to avoid:
- Unwanted access: prevent third parties from entering your private conversations.
- Identity Theft: prevent them from impersonating you to your contacts.
- Loss of information and fraud: protect your data, photos, and messages from scams and fraud.
- Public display of data: control what personal information you share and with whom.
The threats are constant , from fraudulent messages and phishing attacks to social engineering techniques that seek your verification code. That's why taking a few minutes to review your settings is a crucial step to stay safe.
Configure your account privacy settings in a personalized way
The first step to protect your WhatsApp account is review and adjust all privacy optionsThanks to continued advancements, you can now granularly decide what data to display, to whom, and when.
1. Hide your profile picture, status, and last online time
Share only what's necessary. From the Settings > Account > Privacy menu, you can configure whether you want your photo, status, and last seen to be visible to everyone, only your contacts, some people, or no one.
- Profile picture: Avoid leaving it visible to strangers so they don't use your image for fraudulent purposes.
- Status and information: Limit viewing to only your contacts or a custom list.
- Last connection and online: You can hide this data from everyone or select an exclusion list.
These small changes ensure that your personal information doesn't end up in the wrong hands , making it harder for identity theft or scams.
2. Check your statuses and read receipts
If you are one of those who publishes statuses regularly, choose who you share them with: all your contacts, just some, or a specific list. This way, you have complete control and prevent strangers or unwanted people from accessing your updates.
Additionally, you can disable read receipts ('blue double check') so that no one knows if you have read their messages, a very useful feature if you value discretion.
3. Limit who can add you to groups
Being added to unknown groups can be dangerous, as your number and data may be exposed to outsiders.
- Accede to Settings > Account > Privacy > Groups.
- Select “My contacts,” “My contacts except…”, or “Only selected people.”
- This way, you'll prevent strangers—even those with your phone—from adding you without your consent.
Don't forget to update this setting if you add new contacts to your address book.
Activate two-step verification for double security
The most robust method against hacking and impersonation is two-step verificationThis involves setting a 6-digit PIN that WhatsApp will ask you for periodically and every time you register your number on a new device.
- Step 1: Go to Settings > Account > Two-Step Verification.
- Step 2: Activate it, choose a 6-digit PIN, and add your recovery email.
- Step 3: If you forget your PIN, you'll receive a link to your configured email.
Never share this PIN with anyone , not even family or friends. This is the only way to prevent them from taking control of your account, even if they obtain your SIM card or temporary access to your phone.
Recover or change your verification PIN
If you forget your code, follow these steps:
- Go to Two-Step Verification, tap “Forgot your PIN?”
- Choose to disable verification, you'll receive an email with instructions.
- Please reset a new PIN after this process.
Extra protection: protects both your phone and the app itself
WhatsApp security also depends on how secure your device is.If someone has unrestricted access to your phone, all of the above measures could be compromised.
- Activate a blocking method: PIN, fingerprint, facial recognition or pattern.
- Don't share passwords or leave your phone unattended.
- Avoid using unsecured public Wi-Fi networks, as they can intercept your information.
Lock with fingerprint or facial recognition on WhatsApp
In addition to the standard phone lock, WhatsApp allows you to add an extra layer of biometric security . You can activate fingerprint or facial recognition to unlock the app, which is essential for those seeking maximum security.
- Open WhatsApp, go to Settings > Account > Privacy > Fingerprint Lock.
- Activate the option and follow the steps to register your fingerprint.
- You can configure when it automatically locks: immediately, after one minute, or after thirty minutes.
If you're using an iPhone, look for the preview option in your notifications and turn it on or off according to your privacy preferences.
Manage and protect WhatsApp Web sessions and linked devices
WhatsApp Web and desktop versions are very useful tools for working or chatting from your computer , but they can also be an access point for intruders if you leave sessions open on public or shared computers.
Frequently check active sessions on linked devices and immediately close any unrecognized access. This way, even if someone has gained temporary physical access to your phone, they won't be able to continue spying on your conversations from another computer.
Make your chats more ephemeral: use temporary messages
Automatically deleting conversations is a powerful feature for those who want to maintain their privacy long-term . You can activate disappearing messages so that texts are automatically deleted after 24 hours, 7, or 90 days.
- Accede to Settings > Account > Privacy > Default Message Duration.
- Select the interval you prefer (24 hours, 7 or 90 days).
- This setting will only affect new chats upon activation, not old ones.
Anyone participating in the conversation will see the message disappear from the chat after the selected interval. This is useful for sensitive conversations or confidential topics, leaving no trace on your devices.
Protect your information with encrypted backups
Cloud backups ( Google Drive or iCloud ) are very useful if you change phones or suffer a theft, but storing them without encryption can expose your messages in case of unauthorized access.
- Opens Settings > Chats > Backup > End-to-end encrypted backup.
- Activate the option and create a unique password or key.
- Remember that if you forget your password, not even WhatsApp can recover your messages.
This feature adds an extra layer of security: the data is saved encrypted and only you can decrypt it.
Advanced tips and best practices against hacking and fraud
Beware of the most common scams!!
Social engineering remains the main attack routeCybercriminals may try to trick you into revealing sensitive information, such as your six-digit verification code, by:
- Phishing: fraudulent links that attempt to steal your credentials.
- Fake raffles or prizes: messages promising gifts in exchange for your data.
- Fake technical support: alleged WhatsApp employees requesting your passwords.
- Account hijacking: pressure to reveal your PIN or verification code after feigning an emergency.
Never share your verification code with anyone . WhatsApp will never ask for it via message, call, or external form. If someone asks for it, it's almost certainly a scam.
Avoid phishing and dangerous links
When in doubt, DO NOT click on suspicious links or download attachments from unknown or unverified senders.
If you receive suspicious messages, block and report the contact immediately. You can do this directly from the chat by accessing the top menu.
Manage the display of messages and notifications
Are you worried that prying eyes might read your messages when you receive a notification in public? Adjust the settings in Settings > Notifications and disable message previews on your home screen. That way, only you will see the actual content when you open the app.
Activity control and constant supervision
Monitor your account activity regularly to quickly detect any unusual activity :
- View paired devices and close unrecognized sessions.
- Change your verification PIN if you have any concerns.
- Contact WhatsApp support if you experience any issues.
Being alert to messages you've sent that you don't remember or the appearance of unknown contacts can save you a lot of trouble.
Exporting and securely deleting chats
If you need to preserve a sensitive conversation before deleting it from the app, you can export the chat and then delete it . WhatsApp makes it easy to download messages and their attachments to save them to your email or device, thus avoiding leaving unnecessary traces in the app.
- Open the chat, tap the options menu, choose “More,” and select “Export chat.”
- You can decide whether to include media files.
- Once exported, delete the conversation so no one can read it without your permission.
Advanced Tools: Hide and Protect Your Most Sensitive Chats
The option of restrict chats with a secret code Adds an extra layer of protection. You can hide specific conversations, which will only appear after entering a code in the search bar. This is ideal if you occasionally share your phone with family or friends and want to avoid the temptation to look at private chats.
Access the chat menu, scroll down to the bottom to find the Restricted Chats option, and follow the instructions to set your secret code.
Hide your IP address and add more privacy to your calls
Messaging isn't the only thing that matters: your IP address can reveal your location and identity during calls . To hide it, go to Settings > Privacy > Advanced and enable the option to protect your IP address during calls. You can also disable link previews to prevent unnecessary information leaks.
Update WhatsApp regularly
Regular updates fix vulnerabilities and add new layers of protection. Enable automatic updates in your App Store or Google Play to stay ahead of new threats.

- Privacy of your chats and encrypted backups.
- Advanced account protection, such as biometric lock and two-step verification.
This menu groups the main controls and it's a good idea to check it from time to time to ensure your preferences are still correct.
