The app uses end-to-end encryption, protecting every message you send to your contacts. There's no independent login, no username or password – the app uses your phone number and your address book, so in theory, you can't pretend to be someone you're not. The app aims to guarantee safe and completely private communication between its users.Īs soon as you start Signal for the first time, you'll notice its security features. This nonprofit software company develops open-source applications and has been supported at various times by Edward Snowden. Signal is an instant messaging app developed by Open Whisper Systems.
