Summary

Moves the AAGUID/AMR incompatibility explanation from the When AMR matching is skipped bullet list into the AAGUID section's existing note block.

Before: The When AMR matching is skipped section had a bullet explaining that AAGUID info isn't in AMR claims. This duplicated context and buried the explanation away from where admins configure AAGUID restrictions.

After:

  • The AAGUID section's note now explains why the two features are incompatible: most IdPs do not send AAGUID information in AMR claims.
  • The When AMR matching is skipped section no longer mentions AAGUID (the note in the AAGUID section already covers this).

- AAGUID restrictions and AMR matching CAN coexist (not mutually exclusive)
- AMR matching is more permissive: IdPs don't include AAGUID in AMR claims
- Remove Apple iCloud Keychain from no-AAGUID list (they do have AAGUIDs)
- Remove AAGUID bullet from 'When AMR matching is skipped' section

:::note
AAGUID requirements and [AMR matching](#use-identity-provider-mfa) cannot both be turned on at the organization level. If AAGUID requirements are turned on, Access skips AMR matching even when the identity provider returns a matching AMR value.
AAGUID restrictions and [AMR matching](#use-identity-provider-mfa) can both be turned on, but AMR matching is more permissive than independent MFA when AAGUID restrictions are configured. Most identity providers do not include AAGUID information in their AMR claims, so Access cannot verify that the authenticator used for IdP MFA is in the list of approved AAGUIDs. If the IdP returns a matching AMR value, Access will skip the independent MFA prompt regardless of which authenticator the user used at the IdP.
