Single sign-on is an identity arrangement that lets a user authenticate through an approved identity provider and access connected applications without a separate application password for each one. In enterprise procurement, SSO can support centralized identity policy and offboarding, but authorization still depends on application roles, provisioning, configuration, session controls, monitoring, and customer-specific security design.
In plain English
It lets users sign in through the organization’s approved identity service.
Illustrative example
At Northstar Industrial Systems, employees authenticate through the enterprise identity provider, while VendrNova roles determine which procurement actions they may perform.
