"Single-use codes are codes users can have sent to their phone via text message (as long as that phone is already associated with the user’s account) that can be used to sign in to an account without needing the password. That way, a user can sign in on a public computer without worrying that a keylogger might capture the account’s password."
Does this mean I can spam someones SMS by requesting periodically to log onto their account using SMS code to the associated cell phone number?
