Passwordless Authentication and YubiKey - The Future Trend in Security

Passwords have long been a common means of authentication in securing information, reflecting their importance in protecting personal and business data. However, over the years, passwords have revealed significant limitations such as being easily guessable, susceptible to increasingly sophisticated attacks, and challenging to manage as the number of accounts grows, presenting challenges for users.

What is Passwordless Authentication?

Passwordless authentication is a method that allows users to access a service, application, or IT system without entering a password or answering security questions. Instead, users are authenticated using biometric factors such as fingerprints, facial recognition, or by using a hardware device, such as the FIDO security key.

Advantages of Passwordless Authentication:

  • Enhanced Security: Passwordless authentication eliminates the human factor from the authentication process, thereby reducing the risk of attacks.
  • Convenience: Passwordless authentication allows users to access accounts quickly and easily without the need to remember or manage passwords.
  • Ease of Use: Passwordless authentication does not require users to memorize or manage passwords, making it user-friendly.
  • Resource Efficiency: Passwordless authentication consumes resources based on the volume of work and overall resource consumption.
  • Predictive Capacity: It anticipates responsiveness in the future
  • Recommendations and Suggestions for Tasks to be Performed.

Types of Passwordless Authentication:

There are various types of passwordless authentication, including:

  • Biometric Authentication: Uses the biometric characteristics of users for authentication, such as fingerprints, facial recognition, voice recognition, iris scans, etc.
  • Device-Based Authentication: Uses a hardware device for authentication, such as the FIDO security key.
  • App-Based Authentication: Utilizes a mobile app for authentication.

Trends in Passwordless Authentication:

Passwordless authentication is becoming increasingly popular and is being adopted by many organizations and businesses. According to a Gartner report, by 2023, 60% of organizations will use passwordless authentication for at least one type of service.

In Vietnam, passwordless authentication is gradually being implemented. Some banks and financial organizations have adopted biometric authentication to verify customers during online transactions.

YubiKey: A Secure and Convenient Passwordless Authentication Solution

YubiKey is a type of FIDO (Fast Identity Online) security key used for passwordless authentication. YubiKey can be used for two-factor authentication (2FA) or passwordless authentication.

To authenticate with YubiKey, users simply plug the YubiKey into the USB port of their computer or phone, then press the button on the YubiKey. YubiKey will generate a unique authentication code used to verify the user's identity.

Advantages of YubiKey:

YubiKey is a physical security device used to enhance the security of online accounts. YubiKey boasts several advantages over traditional authentication methods like passwords or one-time passwords (OTPs), including:

  • Security: YubiKey employs robust encryption algorithms to generate unique authentication codes. Consequently, YubiKey is highly resistant to attacks.
  • Convenience: YubiKey is compact and easy to carry, requiring users to simply plug it into a USB port for authentication
  • Compatibility: YubiKey is compatible with numerous services and applications, including Google, Microsoft, Facebook, and more. This compatibility facilitates easy use of YubiKey to protect vital user accounts.
  • Anti-Phishing: YubiKey features anti-phishing capabilities, helping prevent malicious actors from using fake YubiKeys to infiltrate user accounts.

How to Use YubiKey

To use YubiKey, users need to install the YubiKey driver on their computer or phone. Subsequently, users can add YubiKey to their accounts on supported services and applications. When logging into an account that supports YubiKey, users will be prompted to plug YubiKey into the compatible port and perform a touch operation on YubiKey to authenticate.

Some Notes When Using YubiKey

  • Keep YubiKey in a secure place to avoid loss or misplacement.
  • It's advisable to have a spare YubiKey in case the primary YubiKey is lost.


With the continuous advancement of technology, passwordless authentication is gradually becoming the predominant authentication method of the future. If you are seeking a secure and convenient solution, YubiKey is an innovative tool that provides peace of mind and flexibility in protecting your personal information. It combines robust security features with user-friendly functionality.
