When the new Signal messenger was released, it applied the highest security standards to all chats. It is the Signal protocol developed by the creators of this messenger, and before they released their own product, that protocol had been applied to ensure the data protection in 'secret chats' by Facebook and Google.

It uses the end-to-end encryption, and the cryptographic protocol is one of the strongest in the world. The main feature in favor of Signal for desktop is the highest level of communication security which is provided by this product. After that it will be possible to add the PC client under the same account and synchronize it with the main mobile app.

The application must be installed on the smartphone and be registered to the phone number to create an account. Initially the Signal messenger was the mobile application for Android phones and iPhone, and this form remains its main one.
