Abstract
Embodiments utilize two types of passwords that each, separately, allow a device user to logon to a network. The first is a master password that allows a user to log on at any time. The second is a turn-varying password that changes with each logon and is valid for only one logon. The network may be accessed by using either the master password or the turn-varying password. The turn-varying password may be presented to a user at the device. A device and a network apparatus may each initially synchronize and maintain a turn state that is based on a number of user logons. When a logon occurs, the device and network apparatus update the turn-varying password for the next logon using the turn-varying password. If a user is in an unsecure location and logs on only using the turn-varying password, a sniffed or stolen turn-varying password is not useable.
