Federated Identity Management: Balancing Security and UX
🔐 Federated Identity Management (FIM) enables a single authentication to span multiple applications or organizations, letting users sign in once and reuse identity assertions across services. It improves user experience and resilience while introducing architectural complexity, potential vendor lock-in, and additional service costs. Implementations commonly rely on cloud identity providers such as Google, Microsoft, or Okta and use protocols like SAML, OAuth 2.0, and OpenID Connect.
