Signal – Getting Started with Secure SMS

Signal

You’ve probably heard of Signal lately; on the news, on Facebook, or somewhere else on the Internet. My sister “tried” to use it, but only ended up missing a bunch of text messages from me. So this post is for my sister and anyone else interested in securing their text messages.

Why Would I Want Secure Text Messages? Are People Really Reading My Texts?

These are two of the most common questions that I get about this. A lot of you Apple users just love your iMessage. Guess what?!? Signal is, for all intents and purposes, the same thing as iMessage except for the following very big differences:

  1. It’s available on both iOS and Android, as well as your Desktop (Windows, Linux and MacOS).
  2. The messages, photos, videos, and even the calls sent between users are only viewable by those users.
  3. It’s Open Source. This means that the software code that was used to create it is freely viewable on the Internet, and anyone can contribute to the development of the program.

Getting Started with Signal

  1. Getting started with Signal is easy. The application is available on both the Play! Store on Android and the App Store on iOS. Once you’ve set it up on your mobile device you can install it on your desktop computer to send messages to other Signal users.
  2. When you first open Signal you’ll need to go through a basic registration where it will validate your phone number.

That’s it! You’re done.

You’ll want to send future texts using the Signal app so don’t forget to update the shortcuts on your phone screen. You may also need to make Signal your default SMS app, which it will prompt you to do when you launch the app.

What If My Friends Don’t Have Signal?

The Signal app allows you to send messages to everyone, even if they don’t have the Signal app. The only issue is that the messages between you and those people will not be secure, and functionality like video calling won’t work.
