When we implemented this solution, we found that less than 1% of users wrote down and stored their recovery codes.

Then, if they ever lose their cell phone, they can use a recovery code to successfully authenticate and add a new cell phone.Īlthough this approach is simple, it requires users to be proactive and organized about their security. Users can print these master codes and store them somewhere safe. There have been several approaches to solving this issue, the simplest of which is to provide users with a set of “master recovery codes” that never expire.

One of the biggest challenges is how to deal with “device or cell phone” loss. Truth be told, delivering 2FA at scale is hard. To minimize impact, we decided to make adding multiple devices an “option” while offering the ability to disable it, giving you control over your Authy account security.īy default, Authy sets multi-device 2FA as “enabled.” But the question remains: why would a user wish to have multiple devices if that makes 2FA less secure? Inherited Trust So we challenged ourselves to make it possible for users to add more devices without increasing vulnerability. If you have more than one device accessing a 2FA account and any of them gets compromised, your 2FA is also compromised. A single device has a smaller attack surface than what is vulnerable when using multiple devices. What is the rationale to only allow one device per account? Security. Although it’s true that Google Authenticator can be added to multiple devices, this is not due to an intended design choice, but rather a poor design choice (we’ll explain this later). To our knowledge, most 2FA systems today are designed to work with just one device. That, however, has led to some interesting scaling issues which we feel can be resolved by allowing multiple devices to access a single 2FA account. Today, millions of people use Authy to protect their accounts. Our goal was - and still is - to offer the most powerful and scalable authentication framework, which has since grown to become a very significant two-factor platform.

We started Authy with the idea of building a modern two-factor authentication (2FA) framework that would take full advantage of new technologies.

All devices need protectionĪnd that brings us to Multi-Factor Authentication. And because computers and smart devices are cheap enough that we can “own” many of them, you can even buy a computer for your wrist, such as the Apple Watch, or for your head, Snapchat Spectacles. Most of us carry a small, powerful computer in our pockets (cell phone), another computer in our bag (laptop) and sometimes even another smaller computer (tablet). What has changed dramatically is the what “you have” part. Multi-Factor Authentication, where you present “something you know” paired with “something you have.” has been around for decades.
