The Most Secure Texting Apps for 2021

Best Most Secure Messaging Apps

Secure messaging apps are a must now since we live in the world’s digital age, where information travels around the globe in just a split of a second. This may sound a bit of good news, but what if this shared information includes the private ones, like the private message you just sent to your brother earlier, or the report you just sent to your boss’s email address, or the resume that you passed online to apply for work?

It’s actually pretty much not just a “what if” because this awful thing really does happen on the internet these days. With the birth of high-speed computers, wireless devices, and other technologies that produce communication, companies can fully control and exploit all your personal information.

In 2015, the report about NSA collecting nearly 200 million text messages every day got everyone realizing that our privacy on the internet and probably even off is indeed being invaded. Fortunately, genius messaging applications keep all information intact and secure privacy throughout the end of every encryption.

You might have been wondering how we know these messaging apps are really safe to use? Well, we’ve tested them out for you. We explored several different messaging apps and confirmed just how secure they are as they claim to be. Before showing you these top 7 messaging apps, however, let us first discuss why you really need secure messaging apps.

The 7 Best Secure Texting Apps for Chatting Privately

According to the test conducted by EFF (Electronic Frontier Foundation), nearly all of the messaging apps we use, like Facebook Messenger, Kik Messenger, Yahoo Messenger, BBM, Hangout, Viber, Skype, WhatsApp, and Snapchat, have failed to keep in line with most of the messaging security standards.

This study basically suggests that companies may use these messaging apps to collect personal information of each user with our private conversations and use it for advertising and marketing advantage purposes. These apps may do great in giving communication services, but the assumption, if not the fact, that they crave and actually take hold of our private messages is, for certain, a kind of an invasion of privacy.

The commoners and different companies of different industries are not exempted from this internet phenomenon. So they also have some reasons to really include secure messaging apps on their necessities.

Legal and Advisory firms treat their clients as genuine gold that holds the success of their business. Everyone can see why they cannot afford to lose their clients because of some client info leak out.

Health Care holds all the records of their patients. Having patient information leaked out would be a great danger. The finance, Banking, and Insurance industries are on top of the list of industries that badly need secure messaging apps.

Since they hold very sensitive information of wealth and properties, more and more cybercriminals will come after.

Perhaps you’ve already found one or two reasons why you really need secure messaging apps. Now, you’re ready to check out the top 7 messaging apps we especially prepared for you and your info safety and privacy.

Here are the 7 most secure texting apps detailing their chatting and security features:

1. Threema Secure Messaging

Threema Secure

Today, there are many messaging apps that proudly and painfully falsely claim to be the best in the market. Threema is certainly not one of them. This secure messaging app is one of the best. In fact, it is one of the most popular messaging apps today, and it certainly deserves to be.

Threema does what it claims to. It keeps private data away from just about everybody – may it be the government, organizations, or any other cybercriminal. Threema uses end-to-end encryption on private messages, group chats, shared media, and even public statuses.

End-to-end encryption means there’s nothing in between a conversation. The encryption and decryption cryptographic keys are exclusively stored on the endpoints, so there will be no in-between interference in conversations.


When using Threema, private information remains intact. It deletes messages on the servers as soon as they are delivered. Other details like personal and group contacts are stored on the local storage.

To sum everything up, Threema is a messaging app designed to keep your precious private information away from the wrong hands.

In Threema, you don’t use any email ID or phone number. Threema provides a unique Threema ID for you, so you won’t have to input any private information upon logging in.

Another good thing about Threema is that it can send several different file types like doc, pdf, zip, gif, mp3, voice messages, and of course, SMS. On top of that, Threema has a transparent privacy policy, which is an important feature every messaging must-have.

2. Signal Private Messenger

Just like Threema, Signal very much deserves all the attention it gets. Signal’s goal is to give users worry-free conversations with their loved ones, but it seems like it is no longer a mere goal. It has now become an accomplished mission. Yip, over the years of its existence in the market, Signal has satisfied its users with its secure messaging features.

Unlike Threema, Signal uses a phone number. That’s not a problem at all. Signal uses end-to-end encryption in your conversations. The servers don’t save chat history and online activities.

It uses cryptographic protocols to keep messages safe. Signal claims zero percent stored data. All those mentioned features appear to be the proof.


Signal isn’t just all about giving users privacy protection. It also makes sure you’re having a pretty good time navigating through the platform. Of course, as a messaging app, it can send texts and make voice calls, but it can do more than just that. Signal sure has a lot to brag about for a free app, from comprehensive group chats to highly-encrypted archive functionality.

3. Telegram Messaging


Who would even dare to forget Telegram, the biggest competitor of the popular WhatsApp? Like any other messaging apps on this list, Telegram is also geared up with end-to-end encryption, but there’s one different thing about it – the Secret Chats.

4. Wickr

Wickr App

Key Differences Between Regular and Encrypted Messaging App

Whether you’re using an unencrypted and an encrypted messaging app, your messages will be delivered as usual and the texting app will work as it should.

The difference between the two platforms lies in the level of security that they provide. When you use an encrypted messaging platform, every message you send is encrypted and fully protected. However, with a regular messaging app, there is no encrypted, and this creates some security vulnerabilities.

A majority of the encrypted messaging apps available today support end-to-end encryption. With e2e encryption, the moment you type your moment and click the send button, the algorithm on the app converts your text into unreadable data with random symbols and letters. It is transported in this state to the recipient’s device where it is decrypted using a private key. Although the encryption protocol on your chat app may be different, this is how encryption works.

When a message is encrypted, hackers or even your internet service provider can't determine what you’re communicating about when they intercept your internet traffic.

Apart from encryption, you will find other security features on any secure texting app. These features may include disappearing messages, no storing of user data on servers, and more.

Pros and Cons of Using an Encrypted Chat

Today, with digital surveillance at an all-time high, security experts emphasize the importance of using the most secure texting app available. But, what are the pros and cons of using an encrypted chat app, and why should you care about it?

The biggest advantage of using an encrypted instant messaging platform is that you get to fly above the radar and escape digital surveillance – from the government, private companies, and malicious hackers.

A lot of people argue against encryption by insisting that they have nothing to hide so using an encrypted app is not worth it, but this thinking fails to appreciate the complexity of the threats that we face today in the digital world.

With companies tracking you online and building profiles on you, the government listening to what you say and keeping tabs on you, as well as hackers looking for the opportunity to swindle you of your hard-earned money or hold your privacy ransom. The value of a private messaging app is more important than ever.

While a secret chat app can help to keep your messages private, the downside is that criminals can take advantage of the same secure texting platform to further their nefarious goals. Using a private messaging app will allow them to escape the grip of the law.

Texting Encryption: How Does It Work?

Although it may sound complex, texting encryption technology is pretty simple, and it's easy to understand the basics of how it works. When you send a message to someone, the encryption protocol converts the message from its original readable state to gibberish before it is transferred to the recipient. When it gets to the receiver’s device, a unique private key is used to convert it back to its readable state before it shows that the message has been delivered on the app.

Encryption does not just work for text message, it also works for audio messages, video messages, and anything you’re allowed to send on a secret texting app. There are different types of encryption systems, but that’s basically how it works regardless of whether you’re using Android, iOS, or any other operating system.

Encryption technology has been around for many years. The native text messaging app on your iPhone or Android device probably uses some type of encryption technology to protect your SMS messages. Many apps on the Apple App Store and Google Play Store also come with encryption.

Most User-Friendly Private Messaging App

Safety Difference in Using Encrypted Messaging

There’s a notable safety difference when you’re using an encrypted messaging app compared to when you’re using an app that doesn’t offer any form of encryption. Regardless of which private messaging app you choose and what type of encryption protocol it uses, your messages are considerably more protected than if you aren’t using an encrypted chat app.

With an encrypted platform, you can enjoy a secret chat experience. No one can access your messages or keep tabs on what you’re doing on the app – not even your internet service provider. In comparison, with an unencrypted messaging app, anyone can hijack your internet data packets and snoop on your conversations.

When you use an encrypted messaging platform, whether for SMS messages or to exchange videos and other content, you’re fully protected from any attacks online. Hackers won’t be able to initiate phishing attacks on you. If you opt for your disappearing messages and choose for your data to not be stored on any servers, you can chat anonymously online without leaving any traces of your interaction.

In summary, the security advantages of an encrypted messaging service are security and anonymity.
