This wild and feature-rich technology era we are living in has changed the way we stay in contact for good. The standard GSM SMS protocol is long behind, the instant messaging apps and VoIP calls took its place. They are widely popular, they have funny emoticons and multimedia features, and they are most of the time free to obtain and use.
However, while we are enjoying the group chats, sharing photos or trying to impose our opinionated thoughts on various subjects, we eventually think to ourselves:
Oh man, if _____ sees this, I’ll be in hell of a trouble.
And you have to know two things before you start deleting your chat history like a mad man conspiracy theorist.
- Whatever you do, the privacy must be guaranteed to you. If you have doubts, stop using that app right away.
- Most of the apps that are widely-acknowledged, with million users. are not up to the task when it comes to protecting your privacy rights.
Moreover, their security holes can result in loss of theft of personal data and credentials. Some of them can be used for marketing, others for cashing out your bank account. For that purpose, we prepared a list of those who can protect you. The ones that offer end-to-end encryption. Not exclusively the instant messengers we want, but the instant messengers we need.
Top 5 Free Instant Messengers for safe messaging
Wickr Me – Secure Messenger
Wickr is an alternative messenger that is based on end-to-end encryption. Additionally, it has a large area of features, with the majority of them committed to the privacy protection. As the developers stated, they don’t have any insights on sent or received messages and files, even the metadata.
The main privacy-specific features of Wickr are Shredder and Configurable Timer. Shredder lets you delete all your sent/received messages and files. With the Configurable Timer, you can set time expiration limit on all of your messages. Once they expire, they get shredded and sent to the dark oblivion of nothingness rather than to service provider storage. Too bad you’ll need to enter your phone number in order to register.
When it comes to the standard IM features, Wickr is simple and intuitive. The user interface offers simplistic workflow and you should get to know all the features in no time. Yes, you can send video, photo, and voice messages. The issues are occasional glitches and crashes (especially on Android). Of course, that should be resolved with upcoming updates.
Signal Private Messenger
Signal Private Messenger is an amazing open-source app that offers just what you need: end-to-end encrypted messaging for both SMS and instant messages. The first evident distinction from the other available solutions is open source nature of the app. Anyone can look up codes and determine is the app truly secure. Of course, that requires coding knowledge. Nevertheless, that doesn’t diminish the transparency, whatsoever. We, customers, have every right to demand it with every privacy-sensitive app.
As we already stated, all the text/media attachments you sent via Signal is encrypted and it can’t be stored on the server. Additionally, you can use it as a default SMS app and stay in touch with colleagues, family or friends that don’t use Signal. In order to log in, you’ll only need your number. The app, like many others, automatically syncs your contacts list from the address book.
Moreover, besides the standard IM features, Signal lately offers video and standard calls. That is a great thing since you can use one app for all the communication features you can possibly need. The only problems are the lack of support for tablets and missing desktop app for PC use. If we disregard those, Signal is possibly the best secure instant messenger you can get for free.
Dust is an interesting app that is not like others. That can be good or bad, it solely depends on your taste. However, the app functionality and privacy protective features are well acknowledged. It is not as intuitive as Signal or as thorough as Wickr, but you can be safe knowing that your messages are secure and encrypted.
When it comes to security features, Dust offers standard end-to-end encryption with few additional tweaks. The same goes for all user privacy-oriented instant messengers: no one can see sent and received but you. Every Dust message is encrypted with its own unique 128-bit AES encryption followed with added security through RSA 2048-bit key. You can set expiry date for messages (even right after recipient read them), but they will eventually get deleted after 24 hours. In addition, you are safe from screenshots since your name is not visible while texting.
In other regards, UI and all-around usability are often sub-par in compare to its peers. Dust is simple to use but lacks some of the advanced features you would nowadays expect from an instant messaging app. With that in mind, this is a nice app worth trying, but it is behind its competitors in other departments except for privacy protection.
Threema is the unique privacy-oriented instant messenger with respectable security measures and a large variety of standard messaging features. In compare to others, it offers some interesting innovations while preserving end-to-end encryption that matters the most.
Firstly, you don’t need to enter email address nor phone number in order to register for Threema. Registration is done with the specific individual Threema ID. This is a great way to surpass accounts and use a traceless messaging. Besides end-to-end encryption, Threema stores or app related data to your device rather than a server. That way, no one can reach your sensitive data and all messaging participants are hidden. Messages are deleted right after the recipient reads them. It is just what you’ll need from a privacy-oriented app.
However, security is not all that Threema excels at. In addition to the simple and well-designed interface, Threema brings to the table all you can ask from an instant messenger. You can send text, videos, voice messages, and photos. Both in individual and group chats. Moreover, you can send a large variety of files that are commonly not available, like GIF, PDF, MP3, ZIP, and others. That can come in handy in a lot of ways. Threema also offers a pool feature. so your friends can vote on different subjects. In addition, Threema is available as a desktop app, so you can use it on multiple platforms.
Well, everybody heard for WhatsApp! It started as a small project, gained massive popularity in no time, and ended up owned by Facebook. We are aware that Facebook is not best known for privacy protection. Actually, it is known for privacy intrusion scandals that are closely related to corporation data espionage and that NSA thing. However, WhatsApp and Facebook Messanger are not the same. WhatsApp is still most used instant messenger. And it seems that the privacy protection is finally getting some love.
Lately, WhatsApp finally implemented end-to-end decryption and stopped storing your data on their servers. WhatsApp now uses Open Whisper Systems security protocol (the one used on Signal). At least to some extent. The prying eyes of Facebook employees can still find out who is the sender or recipient. Simply put, they collect users metadata for various reasons. Besides that, all of the cloud backups will, by default, store your chat history. For that reason, it is better to disable that feature.
Well, you may ask what is WhatsApp doing on this list? Simply put, the other services are not as used as WhatsApp. Because of the two-way street that is instant messaging, both sender and recipient the same app. So, this last input is some kind of lesser evil. You trade partial privacy with small chance to endanger you for an app that is massively used around the world (more than 1 billion users). It would be great if those people choose Signal over WhatsApp but that is an unrealistic expectation. At least for now.
You can grab WhatsApp for Android here. iOS version is available.
As we all know, most of the apps have similar standard IM traits. But privacy and security are the most important ones and they are too often neglected. Well, the things are changing. Users now ask for better protection rather than flashy emojis. And these apps should serve you justice in that department. We hope you liked our list.
What are yours favorite messaging app? Do you think it offers enough security and protects your privacy?
