About single-button hardware tokens for Two-Step Login (Duo)

At Indiana University, you can use single-button hardware tokens to authenticate with Two-Step Login (Duo). Hardware tokens in use at IU include One-Time Password (OTP) models (see example OTP token) as well as older Duo models (see example Duo token). USB security keys are another option.

Single-button hardware tokens are available at your campus Support Center. There is no charge, but you need to make the request in person. Be sure to bring a photo ID.

Note:

You cannot register a single-button hardware token yourself, and you are allowed only one active token at a time. Your token can be added to any of your group or departmental accounts as well; see Use Two-Step Login (Duo) with a group account.

To see how this works once set up, view a video about using a single-button hardware token.

Single-button hardware tokens are non-transferrable, so if you no longer need yours, dispose of it as e-waste at a reputable electronics recycling facility. Before recycling your hardware token, be sure that you really don't need it anymore (for example, to access HR information after you leave IU).
