Centralized Identity
Centralized Identity is a security and access management concept where user identities, authentication, and authorization are managed from a single, unified system or service. It enables organizations to control and monitor user access to multiple applications and resources through one central point, often using protocols like SAML, OAuth, or OpenID Connect. This approach simplifies user management, enhances security by reducing credential sprawl, and provides a consistent login experience across different platforms.
Developers should learn and implement Centralized Identity when building enterprise applications, SaaS products, or any system requiring secure multi-tenant access, as it streamlines user authentication, improves compliance with regulations like GDPR, and reduces the risk of security breaches. It is particularly useful in scenarios involving single sign-on (SSO), federated identity across organizations, or managing access for large user bases, such as in corporate intranets, cloud services, or educational platforms.
