There are many kinds of apps on computers and mobile phones T think. They are games apps, calling apps, messaging apps…They all look useful to us. But many of them are not secured at all. Therefore, we must be concious when downloading them to use. Most of my students like texting because it is easy to communicate with their friends and relatives, so to support teaching my students in secondary years about security in apps I will teach them “messaging apps”.

Messaging apps make it easy to communicate and connect with people around the world. However, with new ways to communicate and connect via technology, there are also new ways for our privacy and security to be breached. Private messages could potentially be read by third parties, the organizations behind the apps, and governments who collect private information on their citizens. It’s useful to remember that popular apps like Twitter, Instagram, Snapchat, or Facebook Messenger do not use end-to-end encryption, so your conversations and files may not be fully secured. On the other hand, there are many chat apps that offer messaging services that have upped their game on the security and privacy fronts by using end-to-end encryption. This measure prohibits anyone from seeing the contents of the message except for you and the intended recipient. The best secure chat programs are not only becoming more sought-after, they are becoming crucial in today’s technologically-connected world. Here are some features :

  • End-to-End Encryption (E2E)
  • Multi-Mode Communication (voice, text, video)
  • Synchronization Across Platforms/Devices (mobile, desktop, web)
  • Destructing Messages
  • Independence From Big Tech Companies
  • Open Source

Secure messaging can involve a lot of elements, so we have chosen the most important factors to qualify an application to be a secure messaging app. End-to-end encryption, multi-mode messaging, and synchronization among different platforms/devices are the three main keys to look for when deciding on the best messaging program to use.

  • End-to-end encryption is a way of creating secure messaging apps by encrypting information so that only the players engaged in communication can read the messages, excluding Internet service providers, the app maker, the government or anyone else. From the moment a message is typed, to the time it spends in transit, to the second it’s received, no one else can see that message. Currently, this method is the safest, most private method of messaging. If an app is not end-to-end encrypted, deem it non-private. The message only decrypts using a locally stored key or secret code when it passes from the sender to the receiver, ensuring direct secure messaging. Encryption does not allow copies of messages to be stored anywhere, including on servers.
  • Multi-mode communication allows for users to send messages through texts, videos, and audios When a platform allows for messages to be send via multiple modes, it usually allows the user to delete whatever kind of message comes through.
  • Multi-platform support provides the opportunity to sync messages across mobile, web, and desktop platforms. If a user feels more secure storing private messages in one location and deleting them off of another, this can up one’s data privacy.

There are a multitude of viable, available options out there when choosing a secure messaging program that emphasizes data privacy. We have created a list of the best, most reliable messaging apps that keep your information secure and confidential- to make our list, an app must have end-to-end encryption, synchronization over multiple platforms/devices (mobile, desktop, tablets), and multi-mode communication (voice, video, audio). Then, we have listed out additional features after those key ones that make an app secure.

Here is the best secure messaging apps on the market today I think. That’s Signal Private Messenger

Millions of people use Signal for instant, free, and encrypted communication because it is known as one of the most secure messaging apps on the market. Signal secure messaging is one of the only apps that has its privacy-preserving technology always enabled; this default system ensures that there is never a risk of sharing moments or sending messages to a non-intended recipient. Signal is a cross-platform encrypted messaging service dedicated to end-to-end encrypted voice calling and encrypted texting. Encryption has always been the core of the company’s product, and when it was acquired by Twitter, the aim was to improve its privacy-protecting platform even further. For more security, users have the ability to choose different disappearing message intervals for each conversation that they have saved in their chat history. Signal is an Open Source project supported by donations and grants, so there are no advertisements, no affiliate marketers, and no secret tracking. Signal doesn’t have the keys to decrypt messages, so the company will never have access to content its users are exchanging.
