User Problem

External Users can be required sign in through an org controlled SSO, but these users are billable.
See Available external user security policy and settings

Not all external users are equally trusted. So it should be possible to have multiple groups of External Users and require most to undergo the security step up, but others if you know they belong to a trusted organisation or domain should be able to bypass this step up.

Suggested Solutions

Enable a multiple external user security policy or implement add conditions to apply the security policy.
