Security is one of the vital factors which keeps your online conversations safe within a messaging app. In this blog post, I’ve reviewed the 10 best encrypted messaging apps that are popularly known for maintaining a well-built security infrastructure. 

Chat App Security is one of the vital factors which keeps your online conversations safe within a messaging app. 

Every app claims to be safe. But, many of them still fall prey to data hacking and malware attacks. Also a few app owners, third-party organizations and Governments could still read private messages to collect information on you. 

While this stays a threat to privacy, there are a good number of apps that take security quite seriously. They focus on modern privacy while perfectly balancing to offer immersive communication features. 

And I’d like to introduce the best 10 among them in this article. Let’s jump right in! 

1. Signal

Most Popular Private Messenger


Signal is an incredibly safe messaging app with impressive chat features and powerful encryption tools.

When you use Signal, you will not be distracted by annoying ads or affiliate marketing. Neither will it track your data for any marketing purposes. Yes, Signal purely focuses on respecting your privacy and providing the most secure messaging experience. 

Also, it is convincing to know that Signal does not save any of the encryption keys. This means, it cannot cipher your conversations – read your texts or listen to your calls. 

Besides, there are a good number features you’ve got to explore with Signal, Let’s take a quick peek at them below:}

2. iMessage

Best Secure Chat App for Apple Devices


iMessage is designed to be secure and is built with End-to-end encryption. 

Its security protocol does not allow any third party access to read your conversations when they are in transit. This app comes with its own style of messaging features and makes conversations more immersive and safe. It offers users complete control over their messages and allows them to choose their own privacy options. 

For example, iMessage users can set a limit to the number of times a message can be viewed.  

However, one setback of this service is that, when you backup your chat in iCloud, some of your messages can be accessed by law enforcement.

iMessage utilizes the Apple push notification service protocol, that establishes a keep-alive connection with Apple’s servers. Each connection has a unique code, serving as an identifier for the route needed to deliver a message to a specific device. That’s why iMessage requires a consistent internet connection to operate, and it won’t function properly if there is no service on iPhone.

  • Notification Muting
  • Block Contacts 
  • Disappearing iMessages and Media
  • iCloud Backup

To Wrap up,

If you’d ask my personal choice among these secure messaging apps, I have 3 picks – Signal, Whatsapp and Telegram. All three apps have transcended from being a mere chat app to a powerful  communication tool to this tech-savvy generation. 

When comparing the three platforms, 

  • Telegram is subjected to handover a few user information to Governmental forces to keep national security at sane level. 
  • Whereas, Whatsapp is bound to share user data to its parent company Meta that focuses on providing customized services. 
  • In this case, Signal stands top on my list since neither it has data to share nor it focuses on Monetization. So, I call it loud again – Signal is the most secure messaging app you can use in 2022.
