What do business and technology magnate Elon Musk, Twitter CEO Jack Dorsey, and infamous whistleblower Edward Snowden all have in common? They all swear by Signal, the encrypted, private messenger service. There are plenty of messaging applications available on the market and, like Signal, some are cross-platform and encrypted, such as Telegram and WhatsApp. However, if you strip away the secondary features and come down to the heart of the matter – privacy – Signal always beats the competition.
In terms of security, WhatsApp and Signal have the same, undoubtedly secure, encryption. However, WhatsApp has suffered from a multitude of hacks that Signal has not; for instance, Jeff Bezos’ famous phone hack back in January of 2020, the NSO Group hack, and a handful of others.
However, the difference between the two applications is that while WhatsApp’s protocol is the only open-source part of the application, the entirety of Signal is open-source. This means that anyone can see the app’s source code. Consequently, both the everyday user and high-level security experts can go through the documentation and ensure their data is as protected as the application claims. Even better: since the open-source protocol is responsible for powering the end-to-end encryption, Signal – the company, itself – is unable to view your messages, calls, etc.
Signal’s best selling point is that neither the application nor the company stores any user data. Since an individual’s data is not being stored, it is impossible for government agencies and other tech companies to request access and thus, the possibility of the data being disclosed is next to none. It is truly the epitome of both a private and secure messaging app.
In conclusion, in the words of Elon Musk: “Use Signal.”
