User Account Creation Involving a Mobile Device

Mobile devices may often communicate with network (“cloud”) services that require an account. Because it may be undesirable to require user interaction when creating an account, it may be desirable to create an account associating a mobile device to a network service without requiring a user to explicitly enter authentication information, such as a username and password. In an embodiment, data corresponding to a mobile device is obtained to generate authentication information which is then sent to messaging address of a user. In another embodiment, in response to an event, a mobile device obtains an identifier for a user, sends the identifier to a server, where the server transmits one set of authentication information to a messaging address associated with the user and another set of authentication information to the device.
