Westlaw is transitioning away from using the Westlaw password and moving to the web standard of "OnePass" username and password for log-ins to their different portals (lawschool.westlaw.com, TWEN and Westlaw). See here for the timeline for implementing the password security changes and requirements for creating a strong OnePass log-in.
Please note that alphanumeric Westlaw passwords will no longer be active after September 29th 2009. If you now log-in to Westlaw with your Westlaw password, please create a OnePass username and password or update your exisiting OnePass accounts during the grace period.
