US Patent 11570165 Single sign-on 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 facilitate an authentication flow. A soundwave is played through the client device that contains a secret key, which is then sent to a service that validates the secret key. An association between the user account and the voice assistant device can then be created so that access to third party services can occur.
