A Short Guide to Choosing The Most Secure Messaging App!

It was just a day or two ago that Facebook CEO Mark Zuckerberg declared that his team has added another layer of privacy and  security to WhatsApp thereby making it a  highly scalable end-to-end encrypted messaging service platform. With such news coming your way and your retrospective knowledge of the fact that your privacy is often breached, you would like to settle for a highly secure messaging app wherein the information shared is read by none except the intended recipient. 

So, let’s move on to get a better grasp of secure messaging apps.

Things to Consider When Selecting a Secure App Messaging Service 

When choosing between different messaging services, one must emphasize three essential features such as end-to-end encryption, multi-mode communication, and synchronization across different devices or platforms. If there’s more to this by way of additional features then that would certainly be an app to look out for, in the current age of internet surveillance and advanced technologies.

Explained: What Secure Messaging Really Is? 

If your message can neither be opened by your service provider on their server nor be opened by any government agency or third party, rest assured, your message is completely secure and encrypted end-to-end. Secondly, if you can send the message via multiple modes such as text, audio, and video and then deletable by the user, it’s a secure messaging service. Finally, your messaging is secure if it can be synced across different platforms such as the web, mobile, or desktop and at the same time be deleted from one platform while stored on another.

End-to-End Encryption 

It is a method by which a message gets encrypted from the time it gets typed by the sender in any secure app to the time it gets delivered -- a perfectly safe and secure method. Such a message only gets decrypted through a locally stored code and no authority or entity other than the reader of the message can view it.   

Variable-mode Communication 

A platform is considered to offer variable-mode communication if a user can send messages in more than just text format, that is, in audio and video formats as well. A messaging app with such an option also allows the user to delete a message that comes his/her way.   

Synchronization Across Multiple Platforms 

A messaging app that allows for messages to be sent across many different platforms such as the web, mobile, or desktop and where the user can also store the message on one platform while delete on the other is considered as a completely private, safe, and secure platform. 

The Top 10 Secure Messaging Apps 

There are several options available when it comes to choosing any secure messaging app. But, how do you choose one that is dedicated to ensuring complete data privacy and confidentiality? By all means, a messaging app is secure and confidential if it provides for end-to-end encryption, variable-mode communication (text, audio, and video), and synchronization across multiple platforms/devices. Needless to say, the latest privacy labels in such encrypted messaging apps also tell you how much data is being used by those apps at any particular point in time.  

If privacy is your utmost priority, then, you should read about the following ten most reliable secure messaging apps and make a choice that appeals to you the most.
