5 Tips to Improve Security and Protect Your Privacy on WhatsApp

As the Internet impacts all areas of our lives, preserving privacy is becoming increasingly important.

One of the key points is the protection of the privacy of our conversations and the content we share, especially when we are increasingly mobile and, therefore, more likely to lose sight of our devices.

100% security does not exist, but there are always precautions we can take to minimize the vulnerability of these instant messaging applications such as WhatsApp.

5 Tips to improve security and protect your privacy on WhatsApp

Enable two-step verification

WhatsApp> Settings or Settings> Account> 2-step verification> Activate.
This verification adds a security layer to the app if another person tries to enter your account. No person who does not have that six-digit code may use the service with your account.

As with any password, if you don’t remember the code, you will receive a link to the email account that you have previously set up. But be careful: If you activate the verification in two steps and you don’t have your PIN, you will have to spend seven days without using WhatsApp so that your number can be verified again.

And the obvious advice: Don’t share the verification code.

Lock the App

This step is especially useful on a mobile that may be available to other people.
For anyone to open your WhatsApp without permission, you have to lock the phone using PIN code, pattern, fingerprint, or other available options that depend on the model of your phone.

It’s easy, go to the Android and iPhone Settings. But we can add one more nut, blocking the WhatsApp app itself.

On your iPhone, from Settings> Privacy> Screen lock, you can do that without fingerprint and facial recognition. You will not be able to access WhatsApp. That blocking can be immediate, which is blocked every minute, every 15 minutes or every hour.

On Android, you have to go to Settings> Security and privacy> App lock and activate WhatsApp. Then, we go to Settings> Security and privacy and click on Fingerprint ID or Face Recognition. This feature is very new on Android devices, although it was already available on the iPhone.

Remove messages from the screen

We have locked the screen, but if we let the messages appear on the screen, we have not advanced much.

We have three options at our disposal: Show all notifications, which is the default option, Don’t show notifications or Hide sensitive notifications. This will affect all applications, not just WhatsApp.

On the iPhone, we will find WhatsApp notifications in WhatsApp> Settings> Notifications. Here we can deactivate the visual messages, messages of groups, and calls. They can be activated or deactivated separately.

If you have an Android phone, you have to go to Settings> Notifications, Applications and notifications, or Sound and notifications depending on the version of Android. Then we must look for the option On the lock screen, which we will see directly or in the Advanced Settings menu.

Enable double encryption

By default, WhatsApp has end-to-end encryption configured, for greater security in all conversations. To verify this double encryption, primarily if we exchange the first level confidential information, it is only necessary to click on the user’s name and then on “Encryption.” There is a 40-digit security code that the other person can scan to stay safe.

Don’t be added to a group without your permission

For those who use WhatsApp to contact a group of school parents (one for each child ah), of a sport, of the gym, etc., it knows how tiring it can be that other people add us “prep” in a group. And you delete yourself, but then someone puts you back …

In the privacy options that are currently being implemented by the company, we will have the opportunity to choose who can add us to a group. The possibilities are Nobody, All, or My contacts.


With a little work, we can significantly increase the security and privacy of our online data. In addition to the new functions that WhatsApp is continually developing, it is up to us to increase a series of measures that we can classify in common sense, such as not sharing personal information in WhatsApp states.

In Settings> Account has 2 tabs that you must analyze, I mean Privacy and the other Security where you can decide if you want to show the time of your last connection, your profile picture, your status or the reading confirmation.
