## Abstract

Systems and methods for temporarily associating user accounts with voice-enabled devices are disclosed. A voice-enabled device, which may be associated with a default account, may be situated in an environment, such as a hotel room. A user may desire to utilize the voice-enabled device to perform one or more actions. In examples, some or all of the actions may require the use of a system resource not available to the default account. In these examples, the user may provide contact information to be used to send a message to personal device of the user to acquire user account information. Upon receipt of such information, the user account may be temporarily associated with the voice-enabled device, and may be dissociated from the voice-enabled device upon the lapse of a period of time and/or occurrence of a dissociation event.
