What Are The Most Secure Text Messaging Apps?

In today’s hyper connected world, it can be easy to take many things for granted… Like your own privacy.

While convenient, instant messaging apps have lulled many of us into a false sense of security. So much so that we don’t think twice about sharing sensitive messages or images with one another.

With literal terabytes of data being processed everyday, how do we know that our communications are not being monitored?

This is why it’s more important than ever that we safeguard our data and privacy. In this article, we’ll take a look at the most secure text messaging apps available.

1. Signal

Easily one of the most popular secure messaging apps available, Signal is used by millions of people from all over the world. Developed by Whatsapp co-founder Brian Acton, Signal is a privacy-focused app that uses an open source protocol.

As a testament to its popularity, Signal has been approved for use by members of the U.S Senate and their staff. 

The app encrypts end-to-end messages to ensure that your communications cannot be intercepted. Additionally, the company does not hold user’s decryption keys – making it impossible for them to gain access to your information. 


  • Sophisticated data encryption
  • Self-destructing messages
  • Group chats
  • Free-to-use

2. Wire

Built on the Signal protocol, Wire is another secure text messaging app that is gradually gaining popularity.

The app features end-to-end encryption for text and voice messages along with voice and video calls. 

As an added plus, Wire supports multiple accounts on the same device…. So if you’re looking to separate the professional and personal, Wire is the app for you.

Because it uses the open-ended Signal protocol, data privacy is subject to external security audits – thus providing users with superior levels of privacy. 

Available for iOS and Android, Wire was originally based in Switzerland. However, the company has shifted operations to the United States in recent years.


  • Data encryption based on Signal’s protocol
  • Multiple account support
  • Allows for data syncing across multiple devices
  • Free-to-use

3. Threema

Threema offers a variety of interesting features not found on other apps. 

Where other messaging apps are usually linked to an email address or handphone number, Threema instead generates a unique ID key for users… Which allows you to use the app while still remaining anonymous.

Data encryption is handled by the proven NaCl cryptography library to prevent any security breaches.

As is expected, Threema offers a variety of messaging features like encrypted text and voice, picture, and video messaging.

Threema however is not free-to-use. Instead, you’ll be required to make a one-time payment of $2.99. While this may put off some users, the added security is well worth the effort.


  • NaCl data encryption
  • Can be used anonymously
  • One-time payment of $2.99 required

4. Telegram

No list of secure messaging apps would be complete without Telegram.

Renowned for the tight encryption used to secure messages, Telegram is one of the most successful secure messaging apps in the world.

Of note, Telegram users will be able to start secret chats with other users on their contact list.  This feature stores the data locally on the device which further enhances privacy.

Also, messages and images sent on Telegram can be set to self-destruct after a certain period of time. Being one of the more popular messaging apps, chances are good that your family and acquaintances would also be using Telegram.


  • Messages can be set to self-delete after a set period of time
  • Free-to-use
  • Secret chat function
  • Can coordinate messages to groups of up to 200,000 users

Keeping your conversations private are essential in today’s hyper-connected world. With these secure messaging apps, even the most dedicated hacker will have trouble breaking in.
