Nowadays, people own and carry an increasing number of
		  mobile devices, such as smartphones and smartwatches. Since
		  these devices store and provide access to sensitive
		  information, authentication is required to prevent
		  unauthorized access. Widely used mechanisms like PIN and
		  password, however, don’t scale well with the growing
		  number of devices and interactions. We present the
		  preliminary design of CORMORANT, an extensible, risk-aware,
		  multi-modal, crossdevice authentication framework that
		  enables transparent continuous authentication using
		  different biometrics across multiple trusted devices.<br>
