What are the common types and methods of passwordless authentication?

Passwordless authentication can be classified into two main types: possession-based and inherence-based.

Possession-based passwordless authentication relies on something that the user has, such as a device, a token, or a card, that can generate or receive a unique code or link that can be used to authenticate the user. For example, a user can receive a one-time passcode (OTP) via SMS or email, or use a hardware security key that supports the FIDO2 standard.

Inherence-based passwordless authentication relies on something that the user is, such as a biometric trait, that can be used to authenticate the user. For example, a user can use their fingerprint, face, voice, or iris to unlock their device or access an application.

Some passwordless authentication methods can combine both possession and inherence factors, such as using a smartphone that supports biometric authentication and FIDO2. This can provide a higher level of security and convenience for the user.

Some of the common methods of passwordless authentication are:

• One-time passcode (OTP): A user receives a code via SMS, email, or push notification, and enters it to authenticate. The code is valid for a single use and expires after a short period of time.
• Magic link: A user receives a link via email or push notification, and clicks on it to authenticate. The link is valid for a single use and expires after a short period of time.
• Biometric authentication: A user uses their fingerprint, face, voice, or iris to authenticate. The biometric data is stored on the user’s device or in the cloud, and is matched with the registered data to verify the user’s identity.
• FIDO2 security key: A user uses a hardware device, such as a USB key, that supports the FIDO2 standard, to authenticate. The device contains a private key that is paired with a public key that is registered with the service or application. The user plugs the device into their computer or taps it on their smartphone, and optionally provides a PIN or a biometric gesture, to authenticate.
• Certificate-based authentication: A user uses a digital certificate, such as a smart card, that contains a private key that is paired with a public key that is registered with the service or application. The user inserts the card into a reader or scans it with a smartphone, and optionally provides a PIN or a biometric gesture, to authenticate.

What are the benefits and challenges of passwordless authentication?

Passwordless authentication offers several advantages over traditional password-based authentication, such as:

• Improved security: Passwordless authentication eliminates the risk of password-related attacks, such as phishing, credential stuffing, brute force, and password reuse. Passwordless authentication also reduces the attack surface, as there are no passwords to store, transmit, or manage. Passwordless authentication also leverages stronger cryptographic methods, such as public key cryptography and biometric encryption, to protect the user’s identity and data.
• Enhanced user experience: Passwordless authentication simplifies and streamlines the authentication process, as the user does not have to remember, enter, or reset passwords. Passwordless authentication also provides a faster and more seamless access to the service or application, as the user does not have to go through multiple steps or screens to authenticate. Passwordless authentication also supports a variety of devices and platforms, such as smartphones, tablets, laptops, and desktops, to provide a consistent and convenient user experience.
• Reduced cost and complexity: Passwordless authentication lowers the cost and complexity of managing passwords, such as password policies, password resets, password storage, and password audits. Passwordless authentication also reduces the burden on the IT staff and the help desk, as there are fewer password-related issues and requests to handle. Passwordless authentication also saves time and resources for the users and the organization, as they do not have to deal with password-related hassles and frustrations.

However, passwordless authentication also comes with some challenges and limitations, such as:

• Deployment cost and effort: Passwordless authentication requires an in-depth, step-by-step plan to implement new software or hardware and to train users. Passwordless authentication also requires a budget to cover the costs of buying, setting up, and maintaining the devices, tokens, or cards for the users, as well as the software or cloud services for the authentication. Passwordless authentication also requires a migration strategy to transition from the existing password-based authentication to the new passwordless authentication, without disrupting the user access and experience.

• User acceptance and adoption: Passwordless authentication requires a change in the user behavior and mindset, as they have to adopt a new way of authenticating. Passwordless authentication also requires a user education and awareness campaign, as they have to understand the benefits and the risks of passwordless authentication, as well as the best practices and the guidelines for using it. Passwordless authentication also requires a user feedback and support mechanism, as they may have questions, concerns, or issues with the new passwordless authentication method.

• Security constraints and trade-offs: Passwordless authentication is not a silver bullet, and it does not eliminate all the security risks and threats. Passwordless authentication still has some security constraints and trade-offs, such as:

  • Possession-based passwordless authentication methods, such as OTP and FIDO2, are vulnerable to device loss, theft, or compromise, as well as to man-in-the-middle, replay, or phishing attacks. These methods also rely on the availability and reliability of the communication channels, such as SMS, email, or internet, which may be disrupted or intercepted by attackers or network issues.
  • Inherence-based passwordless authentication methods, such as biometrics, are vulnerable to spoofing, cloning, or alteration attacks, as well as to privacy and ethical issues. These methods also rely on the accuracy and reliability of the biometric sensors and algorithms, which may be affected by environmental factors, such as lighting, noise, or dirt, or by user factors, such as aging, injury, or illness.
  • Certificate-based passwordless authentication methods, such as smart cards, are vulnerable to device loss, theft, or compromise, as well as to revocation, expiration, or corruption issues. These methods also rely on the availability and reliability of the certificate authorities and the infrastructure, which may be disrupted or compromised by attackers or system failures.
