WhatsApp vs. Telegram vs. Viber – Security and Privacy Winner

In the recent years, instant messaging apps have seen a great success. However, so has the number of malicious hackers, which made a possible choice between the apps even harder. So which one should you go for from WhatsApp, Viber and Telegram? Here is a brief comparison between the three:

Approaches to Security

All three of them offer end-to-end encryption. In translation, this means that they encrypt the messages sent through their app in order to provide complete privacy both for the sender and for the receiver. Telegram was the first one to use this type of security, followed by WhatsApp and then by Viber, which was the last one to adopt this technique in April last year. However, with Viber you can only enjoy this with the latest version of the app.

Two-Step Authentication

Along with the most recent software update, WhatsApp has also received a two-factor authentication system. This introduces an extra firewall that appears when you log in, for maximum protection of your data, so this is definitely a bonus for them. You have to enter a passcode made up of six digits every time you register a device to an account, and in case you forget the passcode, you can use the email address.

What Does Telegram Bring New?

Meanwhile, Telegram has the upper hand with their Secret Chats. Here, you send messages in a special chat that self-destructs after a while. Moreover, you get to choose when the chat will be destructed. Basically, only the device that received an invitation to a secret chat can join it, at which point the two phones exchange encryption keys. Furthermore, Telegram changes the encryption keys after they are used for more than a hundred times or more than a week. At the same time, this app is specialized in sending various data files.
