At a time when privacy has become more important that never, there are several teams and developers who advocate giving better tools to users, so that they have their conversations safeguarded and can never be looked at by others.
Signal is one of those apps that focuses on privacy because not only encrypts chatsBut it even offers proof that those conversations are really secret. That test is based on comparing a series of digits or scanning a QR code. What happens is that these security codes are not always easy to use, which has led to the same system being put at risk, especially when switching between devices. Now there is a solution given by the Open Whisper Systems team itself.
This he has achieved by altering how security codes work in terms of simplicity. Now only a simple scan is needed for the conversation, and the code only includes the codes instead of the phone numbers. What this does is prevent phone numbers from being inadvertently revealed and potentially exposing the conversation.
New devices and app reinstalls won't always require you to approve someone again to keep the chat. The latest version of Signal has a warning mode which will tell you when the security codes have been changed, but does not make it impossible for you to speak to another participant. This feature is disabled by default, but it will be soon when it will be activated from the beginning for new installations if it ends up working well.
In a time when people distrust more of their governments, Signal is taking more and more consonance.
