# Identity Dependency Graph An identity dependency graph records how accounts, domains, mailboxes, recovery channels, devices, authenticators, providers, administrators, and physical access depend on one another. ## Notebook evidence [[Scanned_20260730-1958]] repeatedly binds owned domains to registrar control, DNS and hosted mail; mailboxes to social and financial accounts; phones to recovery; cloud providers to privileged credentials; encrypted backups to device identity; and physical lodging to access and support. ## Archive significance The notebook’s deepest insight is that identity is not one account. It is a topology. Losing one node can disable several dependent systems, while preserving only passwords omits the relationships required for recovery. ## Relationships [[Identity and Account Continuity]] · [[Continuity Architecture]] · [[Configuration Management Database]] · [[Device Identity]] · [[Domain Identity]] · [[Control-Plane Continuity]]
