In some embodiments, the first device is logged in to a second account. In some embodiments, a third device of the set of devices is logged in to a fourth account. In some embodiments, the second account is associated with a group of accounts (e.g., smart devices in a user's home that are linked together (e.g., by an application for controlling such devices)). In some embodiments, in accordance with a determination that the fourth account is not associated with the group of accounts, the electronic device displays, on the display device, a prompt (e.g., 811B) that includes an option (e.g., 812B) to invite the fourth account to the group of accounts. In some embodiments, the prompt includes an option (e.g., 813B) to use the fourth account as a default account (e.g., an account used for outputting information in response to requests that do not otherwise match a voice profile associated with a respective account). In some embodiments, selection (e.g., 816B) of the default account option causes display of a prompt (e.g., 830B) to log in to the account (e.g., to enter login credentials).
