The technology essential for managing online identities typically includes identity and access management (IAM) systems. IAM provides tools and processes that ensure correct identification and authentication of users across digital platforms. This technology helps organizations control access to resources, manage user privileges, and monitor activities to prevent unauthorized access. Additionally, IAM systems often include single sign-on features, allowing users to access multiple applications with one set of credentials. By protecting user identities, IAM technologies enhance security and reduce the risk of data breaches.
