What Is Two-Factor Authentication (2FA)?

Two-factor authentication (2FA) historically relies on the use of a traditional password, as well as an algorithmically generated one-time password (OTP) as a secondary authentication factor. Between the cost of managing these token-based systems and the lack of security they offer, more companies are looking for a more flexible, secure, enterprise-ready option.

Enter biometrics.

Biometric-based multi-factor authentication replaces what you have (tokens) and what you know (passwords) and replaces them with what you are, your fingerprint, face, iris, or other biometrics, to provide strong authentication that can be customized to fit a wider variety of organizational needs.

Single-Factor Authentication

When you log in with just a username and password, passcode, or PIN, this is called single-factor authentication. This is the lowest level of secure access management an organization can deploy, and should only be used for accessing non-sensitive information, like a mobile game or shared corporate accounts that don’t have access to any private data.

Two-Factor Authentication

The next step up in authentication is 2FA. This is when you use a username/password, passcode, or PIN, and then are requested to input a second security measure, like an SMS or token-based OTP or biometric. Using a second factor is a significant bump in security that should be used for any account that has even marginal access to sensitive data, such as corporate email, social media accounts, or even physical access to secure buildings.

Multi-Factor Authentication

Adding in a third, fourth, or even fifth authentication factor expands the security of any access management solution into the realm of multi-factor authentication (MFA). MFA offers scalable, tiered levels of security that can be deployed for controlling access to the most sensitive of data. Financial records, medical information, government databases, and the like should all deploy various levels of MFA, incorporating several factors, which can include: passwords, secret questions, OTPs, biometrics, location, user behavior, registered mobile devices, and more.

VeridiumID is an End-to-End Multi-Factor Authentication Platform

Organizations need to optimize security by deploying an all-inclusive multi-factor authentication platform that’s highly scalable, leveraging customizable selections of authentication factors to form tiered security levels. This approach allows for the level of authentication to scale with security needs and ensure that it remains convenient for end users to access the information and facilities they need.

VeridiumID is a highly customizable solution that is ready to integrate with any existing identity and access management infrastructure that provides the framework for MFA and biometric authentication to bring strong authentication to any organization.
