Which protocol is most commonly used for Microsoft Office 365 integrations with Okta?

The most commonly used protocol for Microsoft Office 365 integrations with Okta is OpenID Connect (OIDC). OIDC is a modern authentication protocol that builds on the OAuth 2.0 framework, providing a streamlined and secure way to verify the identity of users and obtain their basic profile information.

In the context of Office 365 integrations, OIDC facilitates user authentication seamlessly, allowing users to log in with their Okta credentials and access Office 365 applications without needing to manage separate credentials. This results in improved user experience and efficient identity management, which are critical in enterprise environments.

Using OIDC also means that organizations can leverage features such as Single Sign-On (SSO), consistent user experience across various applications, and strong security practices, making it a favorable choice for integrating with cloud services like Microsoft Office 365.

While other protocols like WS-Fed, SWA, and SCIM have their uses (such as for legacy applications or user provisioning), they do not offer the same level of integration efficiency or modern security features as OIDC when it comes to Office 365.
