This document gives an overview of One Time Password.
In order to improve security through the use of multi-factor authentication, core users of certain campus systems are required to submit a One Time Password after they have authenticated with their local campus credentials. Upon being prompted for the 6-digit One Time Password, users will either use a smartphone app or hardware key fob issued to them for this purpose to generate the code. As implied by the name, each code will work to authorize the user for a single authentication session, meaning they will repeat these steps each time they log into their respective system.
Multi-factor authentication is available for both internal and external applications.
UW System users should contact their local campus help desk upon encountering an error when using One Time Password, with the exception of Local Registration Authorities (LRAs). For LRAs and UW-Madison users, the DoIT Help Desk will be responsible for identifying errors encountered when using One Time Password and providing appropriate troubleshooting and/or referral information.
For most types of issues, users may be initially told to contact either their local campus help desk, Human Resources department, or Local Registration Authority (LRA).
The UW Digital ID team also maintains extensive OTP KnowledgeBase documentation.
The UW Digital ID One Time Password service is available 24 x 7.
