One identity across
the Portiko library.

Sign in once at id.portiko.co.uk. Access Cadence, Relay, Quorum, and every other Portiko app via shared SSO. Magic link, no passwords, multi-factor authentication available.

Identity is the canonical user-record service for the Portiko library. Each app (Cadence, Relay, Quorum) keeps app-specific user fields in its own database; identity is owned here. See ADR 0025.
