Signal is an encrypted messaging service for instant, voice, and video calls. The instant messaging function includes sending text, voice notes, images, videos, and other files. Communication may be one-to-one between users, or for group messaging.
The application uses a centralized computing architecture and is cross-platform software. The non-profit Signal Foundation and its subsidiary, Signal Messenger LLC, developed it. This software is free and open-source.
The official Android app generally uses the proprietary Google Play Services, although it is designed to work without them. Signal is also distributed for iOS and Windows, macOS, and Linux desktop programs. Registration for desktop use requires an iOS or Android device.
Signal uses mobile telephone numbers as an identifier for users. It secures all communications with end-to-end encryption. The client software includes mechanisms by which users can independently verify their contacts’ identity and the data channel’s integrity.
The number used for registration doesn’t have to match the one on the device’s SIM card. It can be a VoIP number or a landline, as long as the user can receive the verification code and has a separate device to set up the software. A number can only be registered on one mobile device at a time. Account registration requires an iOS or Android device.
