Yubico’s YubiKey: Review and Guide

The first line of defense to an online account is a username and a password. However, malicious actors sprawling the internet have made the traditional account security combo unreliable and risky per se.

Therefore, SMS-based two-factor authentication (2FA) has been heavily utilized to provide another layer of security. Unfortunately, skilled hackers can still find a way to intercept SMS codes.

To detach account security from the monopoly of software-focused methods, universal second-factor (U2F) authentication was developed. The technology uses open standards under the Fast Identity Online (FIDO) Alliance.

Check out our video explaining what is YubiKey, and its pros and cons.

YUBIKEY REVIEW AND GUIDE: How to keep your Bitcoin and cryptocurrency SAFE

What is YubiKey?

FIDO works to reduce the reliance on passwords when securing internet accounts. YubiKey is a U2F-enabled hardware key developed by Yubico to secure web-based services. Businesses, individuals, and developers can use it.


The key is available in different shapes and connectivity functionalities. While earlier versions only support physical insertions into USB ports on a host device, the YubiKey five series accommodates connection through near field communication (NFC).

NFC allows interaction with the device without physically plugging it into a port. However, the key and the host device must be near each other.

YubiKey Reviews on Amazon

From the reviews left by buyers on Amazon and other platforms, it is evident that the key is a must-have for security-conscious internet users. In fact, 84 percent of the buyers left a five star while nine percent gave a four-star.

One of the reviewers recommended the Yubico YubiKey to developers, IT pros, and “security-minded users.” Furthermore, they praised its manufacturer for providing GUI-enabled YubiKey manager for those having a hard time on where to start.

Others attributed their happiness to the key’s support for password managers such as LastPass. YubiKey users hail it for ease of use as a smart card and its compliance to the Health Insurance Portability and Accountability Act (HIPAA).

Unfortunately, not everyone is happy with their hardware key. Although the negative reviews are minimal, some raise valid concerns.

Among the main problems is documentation, which isn’t user friendly. Additionally, a buyer on Amazon notes that the key “is still too complicated for the average consumer, as it’s not exactly a plug and play device.”

How to Start Using YubiKey

The process of enjoying world-class security on your online accounts starts with purchasing the hardware piece from a reliable platform. After receiving a key, visit Yubico’s website, and choose your key from the list.

Specifying the purchase key from the list helps filter the services where it can be used to provide security. On the services list, select the account you need YubiKey’s hand in boosting its security.

Each service is followed by step-by-step instructions on how to connect to the hardware security key.

Let’s strengthen our account security on Binance.

Note that at the time of writing, Binance wasn’t on Yubico’s list of supported cryptocurrency platforms. Luckily, that doesn’t mean you can’t use the key to provide extra security on one of the largest virtual currency trading platforms.

To do this:

  • Login to your Binance account and click on your profile avatar.
  • Choose “Security” from the options, then “Setup.” On the 2FA section, click on “Security Key.” Note that it only provides the needed extra security layer when accessing the website.
  • Read the note and hit “Continue anyway.”
  • Insert the key in any available USB port and press the button at the hardware’s center to activate it.
  • Activation needs to be done within one minute after inserting the key. However, it can be repeated if you miss this activation window.
  • Once activated, hit “Allow” to the message “Allow this site to see your security key.”
  • Next, verify your account. Note that Binance will need you to provide the authentication code from Google Authenticator if you had previously enabled this step.
  • Binance will then send you an email at the registered address for you to confirm the addition of a new 2-step verification method using something you physically have.
  • After verifying the email, you are done.
