US Patent 11509479 Service authentication through a voice assistant

Disclosed are various approaches for authenticating a user through a voice assistant device and creating an association between the device and a user account. The request is associated with a network or federated service. The user is prompted to use a client device, such as a smartphone, to initiate an authentication flow.

An association between the user account and the voice assistant device can then be created.
