Your identity provider keeps owning identity. BioTone adds a verification surface — multi-signal capture on the user's phone — that the IdP (or any app downstream of it) can require for a specific session, action, or recovery flow.
The integration is the brokered authentication pattern: a web app or kiosk starts a session, a QR or deep link opens BioTone on the user's enrolled handset, capture runs on the phone, and processing follows the selected deployment mode. Your backend validates the signed assertion and applies your configured IdP policy before granting access.
