Session: A Truly Secure Private Messenger for Linux

Session is a free and open-source end-to-end encrypted messenger designed for users who want to protect their freedom and privacy from all forms of surveillance. It works to encrypt all user communications without leaving any digital footprint by implementing a decentralized onion routing network system called onion requests.

One of the best things about Session is that it does not require any mobile numbers or email addresses to operate and users are free to use their real names or an alias.

This allows the software to work without collecting metadata, geolocation data, or any other data about a user’s device and network. Does Session sound familiar? If yes that’s because it is a fork of the much loved Signal private messenger.

Just like any of your favorite instant messaging apps, you can use Session to chat in groups of up to 10 friends or an unlimited number of people using Open Group. You can also send voice notes as well as file attachments, images, gifs, etc.

Session has been the subject of a security paper published in February this year wherein the researchers examined the functionality of its onion requests system and concluded that Session provides access to privacy tools in one modern, user-friendly, messenger. Hopefully, we will get to see more features added as development continues.
