The signal is a popular messaging service that offers end-to-end encryption for instant messaging, voice, and video calls. With Signal, users can send text, voice notes, images, videos, and other files, one-to-one or in a group chat. Developed by the non-profit Signal Foundation and Signal Messenger LLC, the application is free and open-source and works across multiple platforms, including Android, iOS, Windows, macOS, and Linux.
Although the official Android app uses Google Play Services, it is designed to work without them. To use Signal on a desktop, users must register with an iOS or Android device. Signal uses mobile phone numbers as identifiers and end-to-end encryption secures all communications. The software includes mechanisms that allow users to verify their contacts’ identities and the data channel’s integrity.
Users have the option to register using any mobile telephone number, including VoIP or landline numbers, as long as they can receive a verification code and have a separate device to set up the software. It’s important to note that each number can only be registered on one mobile device at a time. Additionally, account registration is only possible on iOS or Android devices.
