Once it is on, you’ll need to enter your passcode or use Touch or Face ID to open up the app. You do this in the Privacy section inside the app, where you switch Screen Lock on. You can add another layer of security to Signal if you enable biometric or passcode access to get into the app. You do this in Settings>Notifications>Signal>Show Previews>Never. This will prevent messages appearing on your Lock screen. You should also turn off Notifications for Signal on your iPhone. You’ll need to provide an actual number for Google’s verification process, but can then use the Voice number to further protect your Signal. To avoid sharing your actual number, it’s possible to use a Google Voice number – just log-in to Voice with a Google account and select a new number. When you create a Signal account, the service will require that you provide a phone number, which becomes your username. You access this tool using a new round icon (it looks like a PS controller) at the top of an image – tap it to activate and Signal will blur any faces it finds in an image. This is designed to help you and those around you retain your privacy. Signal is developing a new tool to blur faces in images you send using the service. Signal will transfer your data from your old to your new iPhone.
Take your old device, select Next and scan the QR code.Open the app and select Transfer from iOS Device.That’s a big benefit if you upgrade your device and it’s very simple to use: Signal recently introduced a new iOS tool that makes it possible to securely transfer Signal data (messages, archived chats) to new iPhones. It's free and works on the iPhone, iPad, Macs, Windows PCs, Linux hardware and Android devices. Signal has a selection of useful features, some of which I explain in this piece. Everyone in a chat should be using it to benefit from this security, particularly if you’re exchanging valuable data. If you are messaging with someone who is not using Signal, then nothing is encrypted. iMessage also offers end-to-end encryption, but is sadly not cross-platform, which gives Signal the edge. It’s open source, uses end-to-end encryption by default and doesn’t store message metadata or use the cloud to back up messages. This makes the content of your messages really hard to intercept (though I hesitate to say impossible, as we live in difficult times).
