For the app to function correctly — especially on MDM-managed devices — administrators must ensure the following permissions are enabled:

Permission	Purpose

Phone	SIM-based phone number verification
Camera	QR code scanning and ID document enrollment
Biometrics	Face ID / Touch ID for passwordless authentication
