Sharing is caring!

WhatsApp is the most popular messaging application of the moment, being used by over 1 billion people from all continents. It was released in January 2010 and four years later, it was purchased by Facebook, entering a new era of changes for the best. On the other hand, Telegram appeared exactly three years ago, but it provided end-to-end encrypted messaging, a feature that WhatsApp has introduced a few months ago. We won’t try to convince you which application to install, because it’s pointless to use Telegram, while most of your friends are using WhatsApp, and vice versa. However, it’s important to know that your chats will be safe and that you won’t fall victim to hackers, and the developers of both applications are doing their best to protect their users’ privacy.

People talk about everything in private. They share dark secrets, organize different events or illegal protests, and if things get out of hand, the police can’t make arrests, in the absence of proofs. And to get their hands on the evidence, the police needs to get access to a user’ device and read his/her conversations. However, the developers of both WhatsApp and Telegram provide a Privacy policy, promising to protect data with all costs.

It is known that on Telegram, users send messages that self-destruct after being read, which means that the application erases all traces of people’s conversations, making it impossible for the police to retrieve them, because they’re deleted from Telegram’s servers. On the other hand, users are able to set a lock with which they can open the application.

WhatsApp uses end-to-end encryption, and when moving to a new smartphone, all conversations will be lost, because they are stored on the old SIM card and most likely, the user will throw it away, if he/she has something to hide.

Telegram users had some problems with hackers especially in Russia and Iran, as their accounts have been compromised because attackers were able to intercept the text messages used by the application to authenticate users. Telegram has advised users to set a secondary password, which would offer an additional protection level.

WhatsApp is also vulnerable to hack attacks, although the application is warning users when keys of their contacts change. Hackers can steal old messages, infiltrate in group chats by impersonating their victims and doing a lot of damage.
