## Authentifizierung

Eine der folgenden Alternativen genügt (ODER). Innerhalb einer Alternative müssen alle Verfahren gemeinsam erfüllt sein (UND).

1. **bearerAuth** (HTTP bearer) — Existing edoobox v2 access token. Never substitute API key/secret headers. **UND** **accountContext** (header: edid) — Selected login/account context from the JWT, not a database primary key. Required even for a JWT with one account.
2. **sessionCookie** (cookie: _edlogin) — Existing browser login session, with the same permission checks as Bearer authentication. **UND** **accountContext** (header: edid) — Selected login/account context from the JWT, not a database primary key. Required even for a JWT with one account.
