A method for identifying a user of an electronic device is presented. In the method, for each of a plurality of users, a bioelectrical impedance of the user is measured, a value based on the measurement is generated, and the value is associated with information corresponding to the user. A bioelectrical impedance of a current user of the electronic device is also measured, and a value based on this measurement is generated. The value associated with the current user is compared with at least one of the values associated with the plurality of users. In response to the comparison, the electronic device is operated based on the information corresponding to one of the plurality of users in response to the current user interacting with the electronic device if the value associated with the current user indicates the current user is the one of the plurality of users.
