Abstract: In some examples, a change in a current viewpoint of a user is detected while a three-dimensional environment is visible. In some examples, in accordance with a determination that at least a threshold amount of the object is visible from the viewpoint of the user, user authorization of the secure operation, using a virtual user interface object, is enabled. In some examples, the user is biometrically authenticated, at a first time, to perform a first type of biometric authentication. In some examples, a request to perform the secure operation is received at a second time. In some examples, in accordance with a determination that the user met respective criteria between the first time and the second time, the secure operation is performed without performing, after receiving the request, the first type of biometric authentication.

Abstract: Embodiments described herein provided techniques to enable peripherals configured to provide secure functionality. A secure circuit on a peripheral device can be paired with a secure circuit on a host device outside of a factory environment without compromising security by verifying silicon keys that are embedded within the secure circuit during manufacturing.
