Federated Identity Management
Authentication system that allows users to access multiple applications using a single identity without sharing credentials across services.
Definition
Federated identity management enables secure authentication across multiple systems using trusted identity providers like Google, Microsoft, or enterprise directories. Users authenticate once and gain access to connected applications without repeated logins.
The system uses security tokens and standardized protocols to verify user identity across organizational boundaries while maintaining privacy and security through encrypted communication channels.
Why It Matters
Users expect seamless access to applications without managing multiple passwords or repeated authentication flows. Federated identity reduces friction while improving security through centralized credential management.
Organizations reduce support costs related to password resets and account management while improving security posture through centralized access controls and audit trails.
Examples in Practice
Slack's federated identity integration allows enterprise customers to use their existing Active Directory credentials for team access while maintaining corporate security policies.
Zoom's federated authentication enables educational institutions to provide students and faculty seamless access to video conferencing using their university credentials.
Salesforce's identity federation allows customers to integrate CRM access with their enterprise identity systems, eliminating duplicate user management and improving security compliance.
