How can you implement single sign-on (SSO) in Azure?

Single sign-on (SSO) in Azure is primarily implemented by utilizing Azure Active Directory (AD). Azure AD acts as a cloud-based identity and access management service, allowing users to authenticate and access multiple applications with a single set of credentials. This means that users can log in once to gain access to various resources without needing to enter their credentials repeatedly.

Azure AD supports various authentication protocols, such as OAuth, OpenID Connect, and SAML, making it versatile for different applications and services. When integrated with Azure Active Directory, applications can leverage SSO capabilities effectively, enhancing user experience and security by reducing password fatigue and potential security vulnerabilities associated with managing multiple passwords.

Other options do not directly support SSO in the way that Azure Active Directory does. For example, Azure Key Vault is primarily used to securely manage secrets, keys, and certificates, rather than handling user authentication. Azure App Service is a platform for hosting web applications but relies on Azure AD or other authentication mechanisms for implementing SSO capabilities. Azure Logic Apps is designed for automating workflows and integrating applications and data, but it’s not focused on user authentication and access management directly. Therefore, Azure Active Directory stands out as the most appropriate solution for implementing SSO in Azure environments.
