Abstract: Disclosed are various embodiments for using an audio interface device to facilitate authentication for other devices. A client device presents an authentication code via an output device of the client device. The authentication code is received from a voice interface device. The voice interface device is in an authenticated state for access to an account, and the voice interface device received the authentication code from speech captured by a microphone of the voice interface device following a spoken wake word. The client device is authenticated for access to the account in response to determining that the authentication code received from the voice interface device matches the authentication code presented by the client device.

Abstract: Disclosed are various embodiments for using an audio interface device to facilitate authentication for other devices. An authentication service causes a first client device to present an authentication code via an output device of the first client device. The authentication service receives the authentication code from a second client device. The second client device is in an authenticated state for access to an account, and the second client device received the authentication code from an environmental sensor while in a listening mode. The authentication service authenticates the first client device for access to the account in response to determining that the authentication code received from the second client device matches the authentication code presented by the first client device.

Abstract: Application developers may develop applications or portions of application that do not have a corresponding user interface. Testing non-user interface elements of an application may require application developers to develop corresponding user interface elements for all or a portion of the executable code included in the application. Developers may test non-user interface elements of an application or library by wrapping the executable code in a sample application managed by a test harness. The test harness may transmit test operations configured to test the non-user interface elements of the application to the sample application over an inter-process communication channel. The sample application may execute the test and return the results of the test to the test harness using inter-process communication methods.

Abstract: Disclosed are various embodiments that perform confidence-based authentication of a user. An identification of a user account is obtained from a user, and a minimum confidence threshold is determined. Multiple authentication challenges are presented to the user. Responses are obtained from the user to one or more of the challenges, with each response having a corresponding authentication point value. A confidence score is generated for the user, where the confidence score is increased by the respective authentication point values of the correct responses. The user is authenticated as being associated with the user account in response to determining that the confidence score meets the minimum confidence threshold.

Abstract: Disclosed are various embodiments for detecting replay attacks in voice-based authentication systems. In one embodiment, audio is captured via an audio input device. It is then verified that the audio includes a voice authentication factor spoken by a user. The audio is then compared with stored audio spoken by the user. If it is determined that an exact copy of the voice authentication factor is in the stored audio, one or more actions may be performed.

Abstract: A resource owner or administrator submits a request to a permissions management service to create a permissions grant which may include a listing of actions a user may perform on a resource. Accordingly, the permissions management service may create the permissions grant and use a private cryptographic key to digitally sign the created permissions grant. The permissions management service may transmit this digitally signed permissions grant, as well as a digital certificate comprising a public cryptographic key for validating the permissions grant, to a target resource. The target resource may use the public cryptographic key to validate the digital signature of the permissions grant and determine whether a user is authorized to perform one or more actions based at least in part on a request from the user to perform these one or more actions on the resource.
