Security as operating infrastructure
Marketing operations touch customer records, payouts, partner work, support conversations, and payment context. Identity, MFA, session boundaries, and provider access controls are not optional.
9010 uses Keycloak, protected dashboard routes, production dependency gates, and multi-channel OTP services as part of the trust baseline.
Why multiple channels matter
A single verification channel fails too easily. SMS, voice, email, WhatsApp, Telegram, RCS, and authenticator flows give operators more recovery paths while provider readiness remains explicit.
