The OTP c100 Security Token is a standalone hardware device that generates a passcode as needed for U-M systems and resources. For those who cannot use the Duo mobile app Duo Security Tokens provide an alternative method for two-factor authentication.

Two-factor authentication adds a second layer of security to your U-M accounts. Verifying your identity using a second factor (like a mobile device or hardware token) prevents anyone but you from logging in, even if they know your password—protecting the university’s and your information.

The Duo Mobile App is the preferred and recommended two-factor authentication option as it provides the easiest and best experience in almost all cases; cellular service is not required.
