Which authentication method is most secure and efficient?
Experts believe that U2F/WebAuthn Security Keys are the most secure method of authentication. Security keys that support biometrics combine the Possession Factor (what you have) with the Inherence Factor (who you are) to create a very secure method of verifying user identities.
Biometric Authentication Methods
Biometric authentication relies on the unique biological traits of a user in order to verify their identity. This makes biometrics one of the most secure authentication methods as of today.
Password-based authentication
Passwords are the most common methods of authentication. Passwords can be in the form of a string of letters, numbers, or special characters. To protect yourself you need to create strong passwords that include a combination of all possible options.
Purchasing a security key device (like YubiKey or Thetis) is the most secure way to receive your MFA code. It's not tied to a mobile number or mobile device that could be breached. Instead, the user uses a small device, about the size of a USB drive or smaller.
Iris recognition on the rise
Iris recognition is widely considered to be the most accurate modality of biometric identification.
The three authentication factors are: Knowledge Factor – something you know, e.g., password. Possession Factor – something you have, e.g., mobile phone. Inherence Factor – something you are, e.g., fingerprint.
Password-based authentication
The most common authentication method, anyone who has logged in to a computer knows how to use a password.
OAuth 2.0 is the best choice for identifying personal user accounts and granting proper permissions. In this method, the user logs into a system. That system will then request authentication, usually in the form of a token.
For web applications that leverage server-side templating, session-based auth via username and password is often the most appropriate. You can add OAuth and OpenID as well. For RESTful APIs, token-based authentication is the recommended approach since it's stateless.
WiFi Protected Access: WPA / WPA2 / WPA3
This authentication method uses different encryption algorithms to encrypt the transport. Therefore, this type of network cannot be forged easily, unlike open networks, and users get privacy. Today, WPA2 is probably the most commonly used method to secure WiFi networks.
Which of the following is the most reliable authentication method for remote access?
Explanation. EAP Allows for arbitrary authentication of a remote access connection through the use of authentication schemes, known as EAP types. EAP offers the strongest security by providing the most flexibility in authentication variations.
Four-factor authentication (4FA) is the use of four types of identity-confirming credentials, typically categorized as knowledge, possession, inherence and location factors.
