        Nowadays we have to pay close attention to our online privacy and should take care to protect it. In today's online world we should take care about things like data theft, digital snooping and surveillance.
Secure messaging has now gan its popularity as most of the users want to protect themselves from hacker and surveillance. Most of the apps have end-to-end encryption which helps to communicate through a secure channel and nobody in between not the companies nor even the government and developers developing these tools can access it.


Here in this post, I want to list few of such encrypted instant messaging app that you all can use as a primary or as an alternate chat app.

It also offers self-destruction of message after a set amount of time. Now in collaboration with, Microsoft is introducing a private conversation feature in Skype which is powered by Signal protocol.

You can see who is online in this app and send messages and since all the communicated is end-to-end encrypted so it is secure from third party eyes. Since the messages travel through Tor network so nobody would know from where and to whom the message is traveling.
