YubiKey 5C NFC Review: The Best Hardware Security Key

There are many ways to secure your online accounts, such as strong passwords, Two-factor authentication like text message codes (OTP), or a 3rd-party authentication app. Even though these methods provide an additional layer of security, sometimes vulnerable to cyber-attacks. One of the best and the most widely used security techniques is hardware-based security keys and the Yubico is one of the most popular security key providers among a few key providers globally.

YubiKey 5C NFC

Adding a security key like YubiKey or any other key from a different brand like Titan Security Key from Google is one of the best ways to keep your account safe. These keys work on top of your passwords. So, even if someone got hold of your password, the person cannot authorize a login without the security key. Also, you don’t need multiple keys to authorize more than one account. One single key can be used with multiple online accounts such as Google, Facebook, Twitter, etc.

Yubico has a wide range of products in its portfolio to fulfill the needs of individuals as well as corporations. YubiKey 5C NFC is the latest addition to its popular YubiKey 5 series and comes with a USB-C plug and built-in NFC for hassle-free connectivity. The YubiKey 5C NFC is fully compatible with Android, iOS, Windows, macOS, and also Linux. You can easily connect the key to any of the compatible devices such as Smartphones, Laptops, and desktops, or tap the key on the devices with built-in NFC.

The YubiKey 5C NFC has a slim USB thumb drive-like design and features a fiberglass reinforced body, and military-grade hardened gold to provide enhanced protection from day-to-day usage. Additionally, the key is water-resistance and also crush-resistant. There is a button (gold ring) at the center and a keyring hole at the top. The button is touch-responsive and not clickable. The ‘y’ logo on the button is backlit, and the green color light glows during the authentication process or when you tap on it.

The YubiKey 5C NFC doesn’t require any battery or network connectivity to start working. Once you plug the key into a compatible device, the application or the service validates the security key when you tap on the button. The key also supports multiple security protocols such as WebAuthn, FIDO2, FIDO U2F, smart card (PIV), Yubico OTP, OpenPGP, OATH-TOTP, OATH-HOTP, and Challenge-response.

How Does the YubiKey 5C NFC Work?

Nowadays, USB-C port is quite common in smartphones or laptops. So, you can make the best use of YubiKey 5C NFC. As it offers two ways of connectivity, you can directly plug the USB-C plug into the laptop or simply tap the key on the rear end of your smartphone that has the built-in NFC like the OnePlus Nord.

Let’s take an example. Assume your email account is secured using a 2FA method. This means, if you need to access your email, first you need to enter your email id, and password, and then, a code is generated through the 2FA app or an OTP is received through the SMS.

It’s quite time-consuming as the code delivery can take between a few seconds and several minutes. Also, you must have your phone with you all the time to get the SMS or generate the code. Additionally, if you don’t use any apps to generate the codes, your phone should always be connected to a mobile network to receive the OTP. Else, you cannot access your account unless you have the backup code with you.

To eliminate such requirements and to enhance the security of your account, hardware-based security keys such YubiKey 5C NFC is used. If your account is protected using the YubiKey 5C NFC (or any other hardware-based key), simply enter the username, and password and then plug the YubiKey into the USB port of the device you’re using. That’s it. The account automatically validates the password with the USB key and gives you instant access to your account.

Note: You can use YubiKey with a countless number of services such as Gmail, Facebook, Twitter, etc. applications. Once you register the key with a particular service (ex: Gmail) each service will simply request you to insert and tap your YubiKey to gain access during login.

Yubico Authenticator (2FA)

An app such as Google Authenticator, Microsoft Authenticator, etc., uses your device to generate access codes. These codes are temporary and expire in 30 seconds. This means the generates a new code every 30 seconds, and you need to enter these codes while logging into your 2FA-enabled account. All such apps store these keys on your phone, and a few apps also allow you to back up these keys online.

One of the best advantages of the YubiKey is the keys are stored in the YubiKey itself rather than the phone or the cloud. YubiKey has its own application called Yubico Authenticator. The app is available for Android, iOS as well as Windows, Mac, and Linux o. Once you install the app on your phone, you need to validate the key by connecting it or by tapping it on the back of your phone (in the case of NFC).

Once the key gets validated, you can add 2FA protection for your services that don’t support hardware-based keys. As all the codes are stored in the key itself, it makes it very easy to move between multiple phones. All you need to do is, install the app on the new or another phone and insert YubiKey to get the codes. You can download the Yubico Authenticator app here.

YubiKey Static Password

Like most YubiKey variants, YubiKey 5C NFC also supports Static Password. This feature splits the password into two parts. The first part is your password, and YubiKey takes care of the second part. Let’s take an example. Cheese777 is the password you are planning to set. The password is easy to remember, but, at the same time, it’s also easy to guess. Using the Static Password, you can make this password stronger and nearly impossible for someone else to guess.

Enter Cheese777 in the password field and insert the Yubikey into your PC’s USB port and then tap and hold the YubiKey button for at least 3 seconds. YubiKey automatically adds additional characters in front of the password you’ve entered. Now, your password becomes Cheese777UT24tchudhrbvblthnvrtifer, where “Cheese777” is a manually entered password by you and UT24tchudhrbvblthnvrtifer is stored in and entered password by the YubiKey.

Click to Play

There is no need to remember the password entered by YubiKey. Next time, during the login, simply enter the username in the username field, and type the first part of the password in the password field i.e., Cheese777 and then insert the YubiKey and press and hold the button for three seconds. YubiKey automatically enters the second part of the password.

Note: You need to tap and hold the button for at least 3 seconds to get the static password. Tapping the button once or for a second or two will generate an OTP string, and that’s not your static password. So, make sure you’re pressing the button for at least 3 seconds.

By default, YubiKey 5C NFC doesn’t include any static password, and you need to configure the Static Password using the YubiKey Personalisation Tool. Using the tool, you can create your own static password with Upper & lower case, Alphanumeric, etc. To set a Static Password for the YubiKey 5C NFC:

  • Open YubiKey Personalisation Tool
  • Insert the YubiKey
  • Click on the Static Password on the top menu and select Advanced
    1. Select Configuration Slot 2
    2. Select the Password Length – 16 or 32 characters
    3. Generate a Private Identify Key by clicking the Generate button
    4. Generate Secret Key by clicking the Generate button
    5. Select Strong Password Policy as per your requirement – Check or Uncheck
    6. Click on the Write Configuration button to complete the process
