Signal is a secure, encrypted messaging service that offers instant messaging, voice, and video calls, with a strong focus on privacy. It supports text messages, voice notes, images, videos, and file sharing in both individual and group chats, ensuring safe and reliable communication.
Signal is a secure, cross-platform solution with a mission. Developed by the non-profit Foundation, the software is designed to serve its users, not advertisers or corporations. It is completely free and open-source, with code available for public review, offering strong transparency and trust within the industry.
Signal is designed to work wherever you are. The app supports all major platforms, including iOS, Android, Windows, macOS, and Linux, for seamless device switching. Unlike many other apps, the official Android app runs flawlessly without requiring Google Play Services. To get started on a desktop, you only need an Android or iOS device for registration.
Your privacy is our priority. Signal identifies users by their mobile numbers and automatically protects every conversation with powerful end-to-end encryption. For added peace of mind, the app lets you independently verify your contacts, ensuring you’re always talking to the right person and that your data channel remains fully secure.
Signal offers flexible registration options to suit your needs. You can register with any number you choose, including a VoIP or a landline, since it doesn't have to match the SIM card on your device. Make sure you can receive the verification code. Each number can be linked to just one mobile device at a time, and initial account registration requires an iOS or Android phone.
