Who can request a token?

UWaterloo employees with an active Workday record can request a token from IST via this form: https://uwaterloo.atlassian.net/servicedesk/customer/portal/2/group/413/create/1660

Students (undergrad and grad), co-op students, and contract staff, retirees and alumni can purchase a yubikey/U2F (Universal 2nd Factor) on their own via Amazon or another vendor. Once the yubikey/U2F token has been purchased, they can program it themselves: https://uwaterloo.atlassian.net/wiki/spaces/ISTKB/pages/262013138/Duo+device+management+instructions?src=search#Add-a-Security-Key

Returning Tokens

When a faculty member/staff leaves, they need to return their token. Either return the token to one of the IST Service Desks in DC or DP, or mail it internally to Chao Yang at EC2 2108C.
