Abstract: Systems and methods described herein allow a customer to employ AR/VR software to generate virtual representations of physical spaces (e.g., house) and sub-spaces (e.g., living room) to preview virtual objects situated in AR/VR virtual environments. A commerce system (or mobile app associated with the commerce system) may generate virtualized environments representing a physical space (e.g., house, apartment) and regions (e.g., living room, kitchen) based on source images uploaded to or otherwise captured by the commerce system. The end-user may operate the software on a client device and interacts with VR or AR presentations of the virtual environment using a voice-based interface recognized by the software. For example, the end-user may say the name of room (region) or an object and the system retrieves data of the identified room or an appropriate room, such as virtual representations of furniture or objects situated in the room.

Abstract: A computer-facilitated service receives a request from a user to access resources provided by the computer-facilitated service. In response to the request, the computer-facilitated service selects an authentication method that can be performed by a remote authentication provider. The computer-facilitated service causes the remote authentication provider to perform the authentication method. In response to an authentication decision provided by the remote authentication provider, the computer-facilitated service determines whether the user has been authenticated by the remote authentication provider. If so, the computer-facilitated service fulfills the request from the user to access the resources.

Abstract: Disclosed are various embodiments for replicating authentication data between computing devices. A computing device detects a change to a user account made by a first client device associated with the user account. The computing device then determines that a second client device associated with the user account comprises locally stored authentication data that fails to reflect the change. The computing device then sends an update to the second client device.

Abstract: Disclosed are various embodiments for repurposing limited-functionality networked devices as authentication factors. In one embodiment, an authentication service identifies a limited-functionality networked device associated with an account and communicatively coupled to the network. The limited-functionality networked device is configured to perform a first function upon a predefined user interaction. The service configures the limited-functionality networked device to perform a second function based at least in part on the predefined user interaction. The service determines that the predefined user interaction has been performed by a user with respect to the limited-functionality networked device. The service authenticates the user at a client device for access to the account based at least in part on the predefined user interaction having been performed.
