Federated Identity Management (FIM)

Definition

Federated Identity Management (FIM) describes an identity system that enables users to use the same login credentials across organisations. Various trusted domains – such as companies, public authorities or cloud services – recognise a central identity source without giving up their own user management. This trust model provides seamless access to resources across organisational boundaries. FIM extends classic single sign-on (SSO) by enabling secure authentication and authorisation processes between independent parties and only exchanging sensitive data in a controlled manner.

Advantages

• Reduced effort through uniform login information
• Higher security through central authentication and MFA support
• Improved user experience through cross-organisational SSO
• Efficient collaboration with partners, external services and cloud platforms

Application in OpenTalk

OpenTalk supports federated identity models to provide users with secure, cross-domain access to the platform. Organisations retain their own identity management, while participants can access meetings and functions without separate logins – both in SaaS operations and on-premises installations.
