Signal is one of the most popular applications in Spain in recent days. The changes in the WhatsApp conditions of service have caused controversy among some users, causing some to decide to search among other alternatives to communicate with their contacts.

Although Telegram is one of the ones that has taken the most advantage of this new situation, another application that has grown a lot in recent days is Signal. This ultra-secure messaging application was known in its day for being the application used by Edward Snowden, but it has also stood out for being recommended by the European Union and by figures such as the famous Elon Musk.

Are you evaluating Signal as a messaging application to communicate with your contacts or are you curious about its possibilities? We tell you all the functions that you should consider so you can know if this application meets your requirements.

Encrypted Messages, Calls, and Video Calls

Despite being gaining popularity in recent days, Signal is a veteran application in the world of messaging. Since its inception, the objective of this application has been to offer the highest degree of security in communications.

Unlike Telegram, where only secret chats are encrypted, here all communications are encrypted. Be it one-on-one chat, group, call or video call, all of them end-to-end encrypted with open source technology. In this sense, Signal is the strongest application.

For mobile and PC

Signal works for both mobile and PC, but its operation is somewhat peculiar. When we install the application on the desktop, the first thing that will appear is a QR code to link our mobile to the desktop application, having to point to this code from the mobile in which we have our active Signal account.

The method is similar to WhatsApp, but unlike this application, Signal will not depend on our mobile being active to work. The only similarity between Signal and WhatsApp is that both link through the desktop application, but in Signal we can continue chatting even when our mobile phone runs out of connection or without battery.

Regarding compatibility, the Signal desktop application offers us support for Windows, Mac and Linux (in Debian-based distributions), so you will be covered in that regard.
