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 secure all communications. The software includes mechanisms that allow users to verify their contacts’ identities and the data channel’s integrity.
Users can register with any mobile telephone number, including VoIP or landline numbers if they receive a verification code and have a separate device to set up the software. Each number can only be registered on one mobile device at a time, and account registration requires an iOS or Android device.
