How To Use Signal Without Revealing Your Private Phone Number

Signal

Signal has made encryption available to the masses, but the secure messaging service also leaves one bit of personal information exposed: Your private phone number.

The app requires a working phone number to register your account, and that can leave you open to harassment and even hackers. Thankfully, there’s a way to use Signal without revealing any personal info at all, though it may require a decent amount of legwork depending on whether you use Android or iOS.

What you need to setup your new Signal account

The Intercept has a full rundown of how to create an account without revealing your personal phone number, but the key detail is that Signal only needs access to a phone network when you first register. After that, it’s all done over the internet.

So all you need is access to a working phone number. That could be a landline, a pre-paid SIM, or another online service such as Google Voice or Skype. Just make sure you have control over the number your using.

If you have an Android phone you’re in luck. You can set up a new account on the device by going into the phone’s settings and selecting “Add user or profile”. Then you can switch between between accounts by dragging down the Android notification tab and selecting the user icon.

If you’re already using Signal on your iPhone it’s a little trickier to set up a second account, since Apple doesn’t support multiple profiles. Your best bet is to just use a separate device, which won’t need a mobile connection to work. You could also use Signal Desktop instead, but you’ll still need to delete Signal from your iPhone temporarily or do some serious coding to get set up.

Take Baby Steps Toward Encryption By Securing Your Smartphone

Your data, from the Christmas party photos you took last year to the tax return you filed (thank God for extensions, right?) is in more places than you think, which means securing as much of it as you can is vital. But the idea of encryption can be intimidating to the inexperienced, and often involves discussion of more esoteric topics like PGP, decryption keys and other terms with which you may be unfamiliar. Fortunately, iOS and Android make it easy to secure your data and protect it from malicious hackers and anyone looking to extract personal information.

How to create your new Signal account

This is the easy part.

When you set up the new account, Signal will send an SMS to the phone number you enter to verify it. If that doesn’t work (like if you’re using an old fashioned landline that can’t accept text messages), it will wait two minutes before calling the number and telling you a verification code. Enter that into the app and you’re good to go.
