Security Assertion Markup Language 2.0 (SAML 2.0) is a version of the SAML standard for exchanging authentication and authorization identities between security domains.

Is OAuth replacing SAML?

They’re not exactly alternatives, more like technologies that can work together. In the Microsoft environment, for example, OAuth handles authorisation, and SAML handles authentication. You could use the two at the same time to grant access (via SAML) and allow access to a protected resource (via OAuth).

Is OAuth more secure than SAML?

Although SAML may seem superior in enterprise settings, there are some scenarios where OAuth makes sense. Identity management for a government application: Use SAML. The confidential, sensitive nature of government data needs the strongest security possible. User experience is a priority: Use OAuth.

Why is OAuth more secure than SAML?

OAuth is more tailored towards access scoping than SAML. Access scoping is the practice of allowing only the bare minimum of access within the resource/app an identity requires once verified. For instance, OAuth is often used when a web app requests access to your system’s microphone and camera.
