OpenFGA — Shared accounts & delegation — POC
The need. A bank account rarely has a single "owner": joint accounts, powers of attorney, proxies, the company accountant. The access model must reflect these relations.
What I prototype
- OpenFGA relations:
holder,co-holder,delegate,accountanton anaccount. - Delegation with limited duration and restricted scope (read-only, capped transfers).
- Immediate revocation and traceability.
