How Does WhatsApp Work?

In January 2018, the number of WhatsApp users reached 1.5 billion, making it one of the most popular applications in the world. WhatsApp has made a huge difference in the way we communicate.

But what exactly does this app do? How does it protect your privacy and what makes it so popular?

What is WhatsApp?

Let’s start with the basics. You can use WhatsApp to text or call other WhatsApp users. Once you have WhatsApp, you can send as many messages as you want for free. Also, there is no time limit on your voice calls.

This app is free and suits many different needs. You can easily share documents via WhatsApp and there is a built-in camera for quick photo and video sharing. It also allows in-line Facebook and Instagram video sharing.

Customizable group chats are among the advantages of the app. WhatsApp allows group calls with up to 256 people per group.

It’s clear why WhatsApp has replaced phone messaging and traditional calling. As long as you have internet access, you can call and message people at no cost. The only limitation is that the other person must also have WhatsApp installed.

How do you install it on your phone?

Here is a quick step-by-step guide to using WhatsApp on your smartphone.

1. Download the App

You can download WhatsApp from Play Store or iTunes. In the early days, WhatsApp came with a small annual subscription fee, but the app is now free to install and use.

2. Accept the Terms of Service

Here are some of the most important things about using this app.

WhatsApp has been part of Facebook since 2014

However, it’s up to you to decide if you want to link it to your Facebook account. Since WhatsApp has been used in the past to collect data for Facebook ads, it might be a better idea to keep them separate. But even if you connect them, your messages and photos will never be shared on Facebook without your permission.

This App Uses End-to-End Encryption

WhatsApp is concerned about the privacy of its users. Therefore, they use end-to-end encryption on your calls and messages.

Everything is encrypted by you and your message is decrypted when it reaches the recipient. Third parties cannot read your messages or listen to your conversations. The company also doesn’t have access to your conversations. WhatsApp does not store your messages, so if you delete them, there is no way to get them back.

WhatsApp No Third-Party Banner Ads

There are no invasive ads when you use this app.

3. Granting the App Access to Your Contacts and Other Data

You can now allow WhatsApp to access your contacts. The app will check which contacts in your contacts have WhatsApp installed. After that, communicating with them will be simple.

This is also where you give the app permission to access your photos and videos. Many people use WhatsApp to share their special moments with their loved ones. Even if you have a slow internet connection, WhatsApp is perfect for video and photo sharing.

You can skip this step for now if you wish.

4. Verify Your Phone Number

WhatsApp sends an SMS to make sure you enter your real number.

Simply enter the 6-digit code you receive via text.

5. Create a Profile

Enter your name so you can start using the app.

You can also use it on your desktop

WhatsApp is suitable for use for a variety of reasons. Among other things, you can send texts and make calls from your computer, but first you need to install it on your smartphone.

The first steps of the installation process are simple. You just need to download a .zip file from WhatsApp’s website and then run WhatsApp.exe (on PC) or WhatsApp.app (on Mac).

After that, you need to scan the QR code from your phone.

If you are an Android user, follow these steps:

1. Open the Chats Tab

2. Select Menu Button

Tap the three-dot icon in the upper-right corner of your screen.

3. Select WhatsApp Web

The app needs access to your camera to scan the QR code. Once you’ve done that, you can log in from your computer at any time.

Mac users should follow these steps instead: Settings > WhatsApp Web.

Last word

Even if you do not plan to use it often, it is useful to meet WhatsApp.

This app can make it much easier to participate in group discussions on your own terms. This makes it especially popular with young people. The app is also widely used by people who travel frequently. If you can find a wifi connection, you won’t have to worry about roaming charges.

WhatsApp is also becoming important in professional contexts. If you intend to use it for your workplace conversations, consider setting up WhatsApp Business. This app is also free and customized to suit your needs as a professional.

But the app cannot completely replace traditional messaging. For example, you cannot use it to contact emergency services. The other downside is that you don’t always have wifi access and using your data plan for WhatsApp can be very expensive.
