Session: An Open Source Secure Messaging App

Due to the multiple and repeated news about WhatsApp's known or probable vulnerabilities, one of the most used messaging applications in the world, by individuals and organizations, many have migrated in parallel or totally, for a long time to other recommended applications such as Telegram y Signal.

En FromLinux, we don't usually talk about WhatsApp, Ya que It is not Free or Open Source Software. We generally do this to refer to your vulnerabilities or to make comparisons with others, especially free and open solutions. As now, we will talk about Session, which is promoted as a open source secure messaging app.

Session: WhatsApp Banned - Banned

I personally have stopped using WhatsApp Totally starting this month of February 2020, since I hardly used it, and despite that, it consumed a lot of data and disk space, among other negative things. I have been using intensively for 3 years Telegram and now absolutely like communication platform I mobile and desktop messaging application.

Minimize or avoid the use of WhatsApp

But, beyond those reasons, real security concerns or reasons, reflected by individuals or organizations worldwide, must be taken into account. For example, regarding WhatsApp, credible news has emerged from organizations such as:

"The european commission has asked its staff to start using Signal, an end-to-end encrypted messaging application, in an attempt to increase the security of their communications. The instruction appeared on internal messaging boards in early February, notifying employees that "Signal has been selected as the recommended application for public instant messaging." The app is favored by privacy activists due to its end-to-end encryption and open source technology.". Political Media - 23/02/2020

"The United Nations Organization they have instructed their officials not to use WhatsApp to communicate. When asked whether UN Secretary General Antonio Guterres had communicated with the Saudi Crown Prince or any other world leader using WhatsApp, UN spokesman Farhan Haq said Thursday: Senior UN officials have received instructions not to use WhatsApp, it is not supported as a secure mechanism". Reuters Medium - 23/01/2020

And for many reasons, information, reasons or news as you are, now a new messaging application makes his way through the public, especially lovers of Free Software and Open Source, a call Session.

    Since smartphones were invented it is practically impossible not to be tracked, and now with the monopoly of Facebook (WhatsApp, Messenger, IG, etc.) we are generating a monstrous big data.

      I would like to belong to this information channel to be updated with the news since I find the software interesting….

    It looks interesting, although something I always want to know is how the application is written in GNU / Linux, because then they are in Electron (software framework) and old computers take years to start it. It would also be nice to know if a continuous connection with the cell phone is necessary like Signal does, which is very impractical from my point of view.

    I was just curious and I'm going to try it heh heh. Regards.

      Greetings, Babel. It would certainly be useful to know that, but neither in its Whitepaper nor in its FAQ section does it show whether or not it is made with electron in a clear or evident way. Regarding the other, I think that by using multi-device synchronization and by using completely anonymous accounts that do not depend on the phone number, since there is no continuous connection with the cell phone. But you would have to test that well to see how it works.

    Have you seen the installation permissions requested on Android? totally ruled out.
    The Protonmail are working on a messaging app, that will be the good one 😉
