What is Signal and Why Does Elon Musk Recommend Using It?

Comments · 92 Views

Privacy is a hot topic and Elon Musk recommends you use a secure and encrypted form of communication.

Tech mogul Elon Musk -- broadly famous for firing vehicles into the sun's orbit as well as for encouraging against COWD-19 protection measures -- took to Twitter recently to slam Facebook over its most current and shady privacy policy adjustments to it’s messaging application WhatsApp. Musk instead recommended that users drop WhatsApp and go with the encrypted and most secure messaging application available, Signal. His Tweet, “Use Signal”


Twitter CEO Jack Dorsey then retweeted the message. Signal shortly afterward tweeted they are working to accommodate the influx of new users.

Moreover, Musk's Twitter endorsement also directly spiked the shares of a completely unrelated biotechnology firm, Signal Advance, which is not a publicly-traded corporation.


Musk and Facebook have sparred before over the shady practice Facebook engages in. Back in 2018, Musk had his personal and his company pages removed from the social network giant. 

Both of the encrypted messaging apps have shown security issues over the years however those bugs were squashed fairly quickly. WhatsApp openly collects certain user data year-round, and thus chances are it will continue to share it with parent company Facebook, especially after it’s latest privacy policy update. Signal, however, has a history of fighting entities that ask for data, and has added features to further anonymize it’s users wherever possible. Simply put, Signal cares about your privacy. 

Here are some basic details on Signal you need to know about if you're interested in using the secure encrypted messaging app.

Signal is an install and use app comparable to any messaging app that you might already have on your phone.  This open-sourced project is free and is used by Edward Snowden, as well as other privacy icons to spread the word about the importance of encrypted communication.


Signal's main function is to send encrypted text, video, audio, and pictures via text messaging, independently verifying the identity of the person on the other end of the connection at the same time. Signal can also be used to make voice and video calls to either a group of people or one on one. 

Yet despite the buzz floating around the term, end-to-end encryption is just that: The process by which a message is encrypted when it is sent, and decrypted by the intended verified recipient. End-to-end encryption prevents law enforcement, mobile carriers, and third parties from being able to read the contents of your messages regardless of whether they intercept them. This is the main attraction to Signal, send messages which can only be read by the verified person you sent it to. 

Signal, has no user data to collect or share. Beyond the obvious privacy benefits, Signal offers extended privacy options, including app-specific locks, onscreen notification pop-ups that vanish without being opened, a disappearing-message function, and the ability to blur your face in photos or videos.

However, bugs have been known to crop up for the technology and are far from being bulletproof. Still, Signal's reputation and success have sustained the software to such a status that it has become a privacy-savvy individual's go-to option for identity protection.

I have been using Signal for the last few weeks and it’s been great. You can see if a message is encrypted or not, which is based on both parties using the app. It’s definitely worth the try and adds another layer of protection from the big tech companies who see you as a product and not a person.
