So, what is dual authentication? Phase 2 authentication definition or 2fa is a method of identifying users using two different types of authentication data. Introducing additional security levels can more effectively protect your account from unauthorized access. This document will help you understand how secure phase II authentication is. Today, many companies rely on Level 2 certification when using this method. For example, if you want to use ukessay to write services, you must also go through this step when logging in to your account. In addition, technical, financial and insurance organizations rely on two factors to ensure the security of customer information. The
Dual authentication requires users to have 2 to 3 types of identification data. These are the types: What he knows What he can use; His inherent (biological knowledge); Obviously, the first item includes various passwords, pin codes, password statements, etc., which are memorized and entered into the system by the user. The second item is a token, a small device owned by the user. The simplest token does not require a physical connection to the computer. A display shows the system number that the user uses to create the project. More complicated is the connection to the computer through USB and Bluetooth interfaces. The
Nowadays, smart phones have become an indispensable part of our lives, so they can be used as tokens. In this case, the so-called one-time password can be generated by a special application (such as Google authenticator) or by SMS. This is the simplest and user-friendly method, which considers some experts unreliable. The authentication method of SMS using the two-level and multi-level authentication example is based on a one-time password. Compared with the permanent password, the advantage of this method is that the password cannot be reused. Even if the attacker assumes that the data can be intercepted in the process of information exchange, he cannot effectively use the stolen password to access the system. But this is not a completely safe factor. The
It may also be an example of implementation using biometric devices and verification methods. This is a fingerprint scanner that can be used on a variety of laptop models. When entering the system, the user must go through the fingerprint scanner and confirm the access authority with a password. After successful authentication, the user is granted permission to use local data on a specific PC. Similarly, other biometric authenticators can be used. fingerprint Hand geometry Outline and size of face Speech characteristics Patterns of the iris and retina of the eye; Draw finger vein; Of course, you will use the right equipment and software, and the purchase and support costs will sometimes vary. The
Need to know about security issues (for biological data), but please understand that there are several dual factor issues. Biometric authenticators are not absolutely accurate data. The fingerprint of a finger may be different under the influence of external environment and human physiological state. In order to successfully verify the verifier, an incomplete match between the fingerprint and the standard is sufficient. The in vivo authentication method includes the definition of the matching probability between the effective authenticator and the standard authenticator. In terms of biometric authentication and remote access to information systems, current modern technologies do not have the function of transmitting reliable data through unprotected channels (fingerprints or retinal scanning results). The
How is the SMS authentication process? The disadvantages of this method far outweigh the advantages and are related to the phone number rather than the verification algorithm. The lost smart phone may be the reason for hackers to invade the online banking system or mailbox. Eventually, the attacker has all the tools to do this. In addition, with the control number, the SMS recovery function can be used without looking up the password. Serious intruders may \
