With cyber attacks becoming more and more common, using a single password to logon to online services is becoming a less effective security measure. Enter two-factor authentication. However, those who’ve used this security process know how much of a hassle it can be – adding additional time to every single login. But not any longer. A small hardware device known as a Yubikey intends to make two-factor authentication easier than ever.
What is two-factor authentication?
Even if you have no idea what two-factor authentication is, you’ve likely been using it already for well over a decade. Two-factor authentication is a security measure that is essentially what it sounds like: you use two different types of identification to verify who you are.
Two common accounts where you’ve likely already used two-factor authentication are email and online banking. Ordinarily when you normally logon to either of these services, you only use a single password – your first method of authentication. However, if you are logging on from a different computer than your usual one, you’re likely asked to go through an additional step to check that you are who you say you are. This happens when you’re prompted for a one-time password – sent to you via text message, email or via some other method. That is your second method of verification, which adds up to two-factor authentication.
Oh, and how have you been using this process for over a decade? Well, another common means of two-factor authentication that’s been in widespread use for over a half century is the ATM. Your physical ATM card is the first form of authentication and your PIN is the second.
Introducing Yubikey – the easy solution for two-factor authentication
Yubikey is a small hardware device that looks similar to a USB drive and is designed to make two-factor authentication on the web easy. In addition to your normal username and password for a given website, it acts as your second form of authentication. Once you’ve registered it, you can use this device with a variety of websites or services that support two-factor authentication. Additionally, you can use Yubikey as a second method of authentication for your computer login, disk encryption for a hard drive, or password manager.
How does it work?
Once you’ve registered your Yubikey with a website or service that supports two-factor authentication, you simply insert the key into the computer, and then tap or touch it to provide your second method of authentication. Bear in mind that the Yubikey is not a biometric device. Similar to an ATM card, its identity protection power lies in the fact that is a physical hardware token. This prevents phishing, malware and other attacks that would need your physical key (in addition to your password) to breach your account.
However, since the Yubikey is a physical piece of hardware, some may wonder, “won’t it be easy to lose?” Well, when was the last time you permanently lost your keys? if the answer is never, then you’re in luck. Yubikey simply attaches to your keychain.
