•Improved
online experience for users
–With SAML
single sign-on (SSO) a user can authenticate with an identity provider and then access various service
providers without additional
authentication.
•Risk
transference, task specialization
–Responsibility for management of identities is given to the identity provider, which is more often compatible with its
business model than that of
a service provider. (The right task for
the right person)
•Reduced
administrative cost for service providers
–The cost of maintaining account information is transferred to the identity provider.
Multiple organizations don't have to independently collect and maintain identity-related data
(e.g., usernames and
passwords).
