Authy lists the service on your phone as little squares with the symbol of the service, and the name you give it. The interface for Authy is very straightforward, easy on the eyes, and fairly user friendly. From then on, any time you log into that service from a new browser or device, you’ll be prompted to type in your password and a randomly generated six-digit code in Authy. Authy will then generate a six-digit code that you’ll type into the website to finish setting it up. If you can’t use the camera, the site doesn’t support QR codes, or you are particularly worried about privacy, you can opt to not give the app camera access and instead type in the text equivalent of the QR code instead. Using the Authy mobile app with camera access, you can scan that QR code, which will give you a code to type back into the website to confirm it’s setup. To get started, when you decide to setup Two-Factor on your service, say on your email account, the site will typically give you a code to type in or a QR code to scan. You can also download an extension in the Google Play Store and as an app on your Apple Watch. Authy is a free app available for iPhone, iPad, and Android on mobile, as well as Mac and PC. Each site works a little different, but almost all of them will work in Authy. Instead, you can and should setup an authenticator app that hold the keys for you. Some services will send text messages, which is better than nothing but less secure due to the nature of text messages. Since a bad guy won’t have access to this device, they can’t get into your account, meaning you’re still safe (you should still change your password though if this happens). This usually gets sent to some device you own, such as your phone. Two-Factor Authentication helps with this by prompting you to type in a special code the company or service sends you after typing in your password. While this may not matter for some sites, a bad guy getting access to sites like PayPal or your bank now has instant access to your money, or if they get your email may be able to reset your passwords and get access to every website you use with that email. But that also means that if that password gets compromised, someone else can have access to your account. What is Two Factor Authentication? On most sites, you enter your username and password, then you’re into your profile. ![]() A good, long, difficult to guess password is the best first step, but after that you should use Two-Factor Authentication. However, no system is perfect and information leaks, including your passwords, are an unfortunate reality. We trust more and more of our work, personal lives, and data to services and companies. ![]() Once you have the app installed and can access your tokens via the app, you may turn off multi-device to prevent access from other members of your family! And update the phone number in the app later without delay.Security is becoming more and more of an issue in this day and age. If you were able to receive SMS in the past but now cannot, your best solution is to see if you can temporarily use an alternate number (perhaps owned by a family member or friend) and install the Authy app. If you used a landline, you're very unlikely to ever be able to SMS messages on it in my experience.Ĭheck this out, Authy Landline - VoIP - connectivity issues, it's a support doc from Authy's website. If I recall correctly, that SMS message is needed in order to authenticate your account when you setup it. That phone number should be able to receive an SMS message. ![]() The reason it keeps asking for a phone number here is a means of identifying your account. I never occurred to me that other users might be able to somehow use Authy without an Android or IOS device. I use Authy for one of my accounts, but that said, I have only ever used this as an android phone app. As I'm sure you know, Authy is a 2FA service.
