What is OTP (One Time Password), and how does it work?
OTP (One Time Password) is an authentication procedure used for secure access to institutional or sensitive data at Indiana University. It uses a physical device, called an OTP token, to help verify your identity to the authenticating service.
An OTP token is a small device, roughly the size of a USB drive, with a single button and a display; they are compact and waterproof. The tokens are DIGIPASS GO 6 authenticators, manufactured by Vasco Data Security.
The cost for a standard OTP token is $25. Alternative devices with additional features for the visually impaired are available via special order (these devices are more expensive). Tokens are a departmental purchase and are re-assignable. Thus, if you change departments, the token stays with the department you are leaving, and you obtain a new token in the new department.
New OTP tokens are assigned via an online self-service tool, where you also set your PIN. See At IU, how do I activate my OTP token or change my PIN?
In June, 2011, OTP tokens replaced SafeWord cards for strong authentication at IU. See About the SafeWord/OTP migration at IU.
