Authentication Architecture: Passkeys, MFA, OAuth 2.0, OIDC and Enterprise SSO

How are organizations adapting their authentication strategies to address modern cybersecurity challenges?

From passkeys and Multi-Factor Authentication (MFA) to OAuth 2.0, OpenID Connect (OIDC), SAML, and enterprise Single Sign-On (SSO), authentication architecture is a critical component of modern Identity & Access Management (IAM).

I've published an article exploring these technologies, key architecture considerations, and practical security principles for developers, IAM professionals, and security architects.
