How it is used
Programs count "Signs in through SSO" per person from Identity provider & MFA and read it beside the other Identity and access signals; it feeds 0 cohorts, 0 sequences and 1 breach scenario.
A "signs in through SSO" event is evidence of a protective behavior; a vigilant behavior at any step breaks a sequence. It is one event, and it does not cancel the risky signals the same person carries.
