FreeRADIUS vs Passport: What are the differences?
Introduction
FreeRADIUS and Passport are both authentication and authorization servers used in different contexts. While FreeRADIUS is primarily used for providing network access and AAA services, Passport is a middleware used for third-party authentication and identity management. Despite serving similar purposes, there are key differences between the two:
-
Architecture: FreeRADIUS follows a client-server architecture, where it acts as a server providing authentication, authorization, and accounting services for network devices. On the other hand, Passport acts as a middleware that enables third-party authentication for websites and applications.
-
Supported Protocols: FreeRADIUS supports a wide range of authentication protocols such as PAP, CHAP, MS-CHAP, EAP, etc., making it compatible with various network devices and technologies. In contrast, Passport mainly focuses on OAuth and OpenID Connect protocols, allowing it to integrate with external identity providers like Google, Facebook, etc.
-
Open Source vs Proprietary: FreeRADIUS is an open-source software widely used and maintained by the community. It provides flexibility for customization and is often deployed in enterprise environments. Passport, on the other hand, is a proprietary middleware developed by Microsoft specifically for integrating with Azure Active Directory and Microsoft identity platform.
-
Use Cases: FreeRADIUS is commonly used in network environments, providing services like Wi-Fi authentication, VPN access, and centralized AAA services for wired and wireless networks. Passport, on the other hand, is used for web applications that require third-party authentication, allowing users to authenticate using their Microsoft or other external identities.
-
Configuration Complexity: FreeRADIUS offers extensive configuration options and requires in-depth knowledge of RADIUS protocols and network infrastructure. It requires manual configuration of clients, realms, policies, and attributes. Passport, however, provides a simplified configuration process by leveraging Azure Active Directory and Microsoft identity platform, making it easier to integrate third-party authentication in web applications.
-
Scalability and Performance: FreeRADIUS is known for its scalability and performance, allowing it to handle large-scale network deployments with high concurrent user connections. Passport, as a middleware service provided by Microsoft, benefits from the scalability and performance of Azure Active Directory, making it suitable for web applications with varying user loads.
In summary, FreeRADIUS primarily focuses on network access and AAA services, supporting a wide range of authentication protocols, while Passport is a middleware solution that enables third-party authentication for web applications, mainly using OAuth and OpenID Connect protocols, and leveraging Azure Active Directory and Microsoft Identity Platform.
