Compare Identity Concepts
Side-by-side comparisons of key digital identity concepts, protocols, and technologies to help you understand the differences and make informed decisions.
SAML vs OpenID Connect (OIDC): Which SSO Protocol Should You Use?
A comprehensive comparison of the two dominant single sign-on protocols. SAML uses XML-based assertions and is prevalent in enterprise environments, while OpenID Connect is built on OAuth 2.0 with JSON/JWT tokens and is the preferred choice for modern web and mobile applications. Learn when to use each protocol, their security characteristics, and migration considerations.
RBAC vs ABAC: Choosing the Right Access Control Model
A detailed comparison of Role-Based Access Control and Attribute-Based Access Control. RBAC assigns permissions through predefined roles and is simpler to implement and audit, while ABAC evaluates dynamic attributes for fine-grained, context-aware decisions. This comparison covers scalability, complexity, compliance implications, and hybrid approaches that combine both models.
OAuth 2.0 vs OAuth 2.1: What's Changing and Why
An analysis of the evolution from OAuth 2.0 to OAuth 2.1. OAuth 2.1 consolidates security best practices into the core specification, mandating PKCE for all clients, deprecating the implicit grant and resource owner password credentials grant, and requiring exact redirect URI matching. Understand what changes are required and how to prepare for the transition.
Passkeys vs Passwords: The Future of Authentication
A comparison of traditional password-based authentication with modern passkey-based passwordless authentication. Passkeys use public-key cryptography and are phishing-resistant by design, while passwords remain vulnerable to phishing, credential stuffing, and brute-force attacks. This guide covers security, usability, deployment considerations, and migration strategies for organizations moving beyond passwords.
Zero Trust vs VPN: Rethinking Network Access
A comparison of traditional VPN-based perimeter security with Zero Trust Network Access (ZTNA). VPNs grant broad network access once authenticated, while Zero Trust verifies every request and grants only application-specific access. This comparison covers security posture, user experience, scalability, performance, and practical migration paths from VPN to Zero Trust architectures.
