Usb security key

Types of USB security keys

A USB security key is known by different names; some call it a USB security token or a FIDO key. The device provides two-factor authentication (2FA) or multifactor authentication (MFA) for safer access to online accounts and computers, among other uses.

USB security keys use cryptographic protocols to protect users’ accounts. They are easy to use and offer a better alternative to passwords or mobile authenticator apps. These security keys come in different types.

• FIDO U2F (Universal 2nd Factor)

  The FIDO U2F keys provide two-factor authentication for various online services using a public-key cryptography model. They work alongside a user’s regular password. When logging into an account, users are required to insert the key into a USB port and touch it. This process generates a unique one-time code for every login request based on the service provider’s public key.

• FIDO2/WebAuthn

  The FIDO2/WebAuthn allows passwordless authentication with compatible devices, apps, and services. The FIDO2 security keys incorporate a second factor like biometrics (fingerprint or face ID) or PINs. They offer enhanced protection against phishing attacks and other similar compromises.

• Smart card-based USB security keys

  These keys resemble standard smart cards, but they also work as USB security tokens for two-factor authentication. Users need to insert them into a card reader and authenticate access with a PIN or biometric verification.

• Bluetooth/NFC-enabled keys

  Bluetooth/NFC-enabled keys have wireless capabilities. Users can authenticate login requests by tapping the key with a smartphone or a device that supports NFC technology. The keys can also connect to devices using Bluetooth. They are more versatile than their wired counterparts since they can work with devices that don't have USB ports.

• Multi-factor keys

  Some USB keys combine several authentication technologies. They offer many authentication methods, including USB, NFC, biometric verification, Pin codes, and others. The keys adapt to different security policies and requirements.

• Legacy USB TOTP tokens

  Time-based one-time password (TOTP) tokens generate one-time passwords that are valid for a short time. They are compact and typically feature a small display for showing QR codes and a button. Users press the button to generate a one-time password that can be used as the second factor for logging into an account.

Function and features of a USB security key

A USB security key is an easy-to-use and cost-effective two-factor authentication solution. It has the following functions and features.

• Strong Two-Factor Authentication

  The primary function of a USB security key is to provide strong two-factor authentication (2FA). In USB keys with random number generation, every login attempt produces a different code that can be used with a password to access sensitive accounts.

• Multi-Platform Support

  Some security keys support multiple authentication methods and protocols, including FIDO2, FIDO U2F, WebAuthn, and OTP. This allows users to authenticate on a wide range of applications and services, even in instances where cross-platform support is required.

• Easy and Intuitive Operation

  Using a security key USB authentication process is simple and fast. Insert the key into a compatible USB port, touch the key (if applicable), or complete the required action to authenticate. This ease of use leads to higher user acceptance and minimizes potential errors in the authentication process.

• Mobile Device Connectivity

  Some USB security keys are provided with NFC or Bluetooth capabilities, which allows them to connect to mobile devices. This functionality is especially useful for users who rely on smartphones or tablets for authentication on the go.

• Resistance and Long Battery Life

  USB security keys are designed to be portable and durable. They are small enough to be stored on a keychain and are built to withstand the rigors of everyday use. In addition, these security keys use a non-replaceable battery that doesn't require frequent charging or replacement.

• Quick Setup and Management

  Administrators can easily enroll the keys, and users can register them on their devices and accounts without complicated procedures. Moreover, key management is straightforward, minimizing the overhead required to maintain an effective 2FA system.

• Cost-Effectiveness

  USB security keys provide an affordable 2FA solution compared to other methods that incur recurring costs. They are an excellent investment for organizations and individuals seeking enhanced security without the associated ongoing expenses.

Scenarios of USB security key

Through various usage scenarios, it is evident that hardware security keys serve as an additional layer of protection against increasingly sophisticated cybercriminals.
