Abstract: Systems and methods for secure information exchange are disclosed. During setup of an accessory device in association with a voice-enabled device, token data may be generated and signed using a private encryption key by the accessory device. An accessory-device system associated with the accessory device may send a request for account identification including the token data to a remote system associated with the voice-enabled device. The remote system may determine if an application associated with the accessory-device system is enabled, and if enabled, may send the account identification in an encrypted format to the accessory-device system.
