How Secure is Whatsapp?


WhatsApp is a popular messaging platform that has been around for a long period of time. It was launched in 2009 and acquired by Facebook in 2014. The application was originally intended to serve as a free messaging service for international communication - however it quickly became popular among other groups and users and currently has around 1.5 billion users worldwide. 

The Rise in Popularity


Recently, the application has been receiving some positive traction due to its encryption features that make their chats more secure than other similar applications. WhatsApp boasts that it features end-to-end encryption for all messages, photos, videos, voice messages, documents and calls that their users share. This means that WhatsApp does not store any sent messages on its servers - the messages are only visible to those that are sending or receiving them. This separates it from other messaging platforms such as Snapchat, which stores its messages on their own internal servers. 

WhatsApp's End-to-End Encryption


Its end-to-end encryption makes it a safer option compared to other popular messaging apps, including Facebook Messenger, Snapchat and Instagram Messages. However, this does not mean that WhatsApp is risk free, the app still collects information for your profile when creating an account - including contacts and personal information. Furthemore, WhatsApp also tracks how much time you are spending on the application. However, this would be comparable to any popular social media application, and does not mean that WhatsApp stands out as being inherently unsafe. 

New Privacy Policy and Controversy

This year WhatsApp released some new changes to their privacy policy that many users were not happy with. The app will continue to be end-to-end encrypted and will not have access to your private chats or location. However, the new update will allow WhatsApp to use "business conversations" hosted with the application for marketing purposes, which can include advertisements on Facebook. WhatsApp claims that it will clearly differentiate between business and casual conversations - however this change has still caused uproar among users. You must accept these new privacy policy terms or the your functionality will be limited within the application.

Keep Yourself Secure

Here are some tips you can take to help mitigate the potential risks of this social media application:

1. Set up Two Factor Authentication

It is always good practice to enable two factor authentication for any application you have. This will require a second piece of information beyond simply your password to log into your account. This added layer of protection will keep your account more secure from hackers or potential cybercriminals.


2. Check encryption

You can make sure that WhatsApp is encrypting your data by opening a chat, tapping the person's name and clicking "Encryption". Although WhatsApp does encrypt all chats by default, it never hurts to be sure.

3. Watch out for phishing scams

4. Adjust your privacy settings

Make sure that you are only visible to the people you trust the most. You are able to adjust these settings under the privacy tab.
