What Is Modern Authentication?

One term in IT that is gaining considerable attention is modern authentication. This post aims to shed light on what modern authentication is, why it is essential for businesses, its protocols, and how it fares against legacy authentication.

What is modern authentication?

Modern authentication is a security mechanism that is designed to provide a more secure and user-friendly method of authenticating users. It employs a variety of protocols and technologies to ensure that only authorized individuals gain access to systems and data. This approach goes beyond mere passwords, incorporating additional factors such as biometrics and device information, providing a more robust level of security.

Why do businesses need modern authentication?

The need for modern authentication in businesses is driven by several factors. The increase in remote work necessitates more robust security measures, as employees access company resources from various locations and devices. Furthermore, the growing sophistication of cyber threats requires more complex and adaptive security measures, like setting up MFA for Office 365 and other everyday tools. By implementing modern authentication, businesses can significantly enhance their security posture, reduce the risk of data breaches, and protect their valuable assets.

Protocols of modern authentication

There are numerous protocols associated with modern authentication. These include:

  1. OpenID Connect: This protocol allows clients to verify the identity of the end-user based on the authentication performed by an authorization server.
  2. SAML (Security Assertion Markup Language): A protocol that allows identity providers to pass authorization credentials to service providers.
  3. OAuth 2.0: This protocol enables applications to obtain limited access to user accounts on an HTTP service.
  4. SCIM (System for Cross-domain Identity Management): This protocol is used to automate the exchange of user identity information between identity domains.

Modern authentication versus legacy authentication

Legacy authentication methods, such as username and password combinations, are becoming increasingly inadequate due to their vulnerability to various attacks. In contrast, modern authentication employs multiple factors and advanced protocols, thereby offering a significantly higher level of security. Furthermore, modern authentication provides a better user experience, as it can incorporate seamless methods such as biometric authentication.


In conclusion, modern authentication represents a significant advancement in information security. With its enhanced security measures and improved user experience, it is fast becoming a necessity for businesses in today’s digital landscape. Adopting modern authentication is not just about keeping up with technology trends; it is a strategic move towards ensuring the safety and integrity of business data and systems.
