| OIDC | Signed ID token, issuer, client audience, expiry, state, nonce and PKCE checks |
| Domain routing | Requires verified ownership and an enabled provider; ambiguous selection requires a provider ID |
| Linking | Work email must belong to the provider’s verified domain; SCIM linking preserves an existing verified account’s profile |
| Provisioning | New members receive viewer; active SCIM requires an active directory identity matched by OIDC subject |
| Enforced SSO | Checked for the destination organization, including existing browser and CLI sessions |
| Owner recovery | Independent password/passkey remains available; required shipd MFA still applies |
| MFA | A successful shipd challenge is required; enrollment or IdP MFA claims alone do not satisfy it |
| Provider change/removal | Provider sessions must authenticate again; removal requires independent credentials and directory decommissioning |
| Password compatibility | Password login remains available; it does not unlock an enforcing organization for non-owners |
