Abstract
Methods for authentication over unsecure networks using one-time passwords methods are provided. The methods establish a connection over a first channel between an authentication system and a user's computing system, then the authentication system determines information based on the connection over the first channel, such as the IP address and other information that can be readily found once the IP address is known. The information derived from the connection is then provided to the user over a second channel, and the user is given an opportunity to review the information before deciding whether to continue the login. If the information returned to the user over the second channel is suspicious, this can indicate to the user that the connection over the first channel has been compromised.
