YubiKey authentication tokens enable authorized users to access a variety of UCAR resources. These include high-performance computing systems managed by CISL (see below) and the virtual private network (VPN).
To be able to use your YubiKey token, you first need to complete the appropriate form and send it to the fax number on the form.
Complete the Duo/YubiKey4 Acknowledgement Form (click to download). If you have arranged to have a YubiKey 4 token, you will use it in combination with your CIT password.
By signing the acknowledgement form, you agree to fulfill your responsibilities as a user and to protect your token as follows:
In addition, you acknowledge that acceptance of this token constitutes an understanding that the token is export controlled such that export/re-export to Cuba, Iran, Syria, North Korea, or Sudan is strictly prohibited.
A user with admin privileges who can tell the system to permanently recognize the token must plug the token in initially. This will let you avoid having to go through three dialog boxes every time you log in.
When the dialog box asks you to press the key to the right of the SHIFT key, touch the button on the token instead.
To log in to a CISL system – Cheyenne, in this example – use the ssh command and your UCAR username as shown.
The system will prompt you to enter a token response.
You can open more than one login session, but you must complete the authentication process for each session before opening another one.
Here are some tips for taking proper care of this electronic device.
Contact the CISL Help Desk if you need to replace or exchange your YubiKey 4 token.
Users who lose or damage a YubiKey 4 token or fail to return it when required will be billed $60. The fee can be paid by credit card on the UCAR Payment Web Site or billed to the user's NCAR/UCAR account key.
For security reasons, the CISL Help Desk cannot routinely arrange temporary access for users who forget to bring an authentication token to work. If you are out of town and need emergency access, the NCAR Research Computing help desk.
Loss, theft, or compromise of a YubiKey 4 must be reported within 48 hours to the CISL Help Desk at x2400 (303-497-2400). Quick reporting will help the organization minimize security risk.
If you return a token intact within three months after having paid for it, we will issue a credit to your credit card or to the NCAR division that paid for the token if you provide a receipt or other documentation that the charge was approved.
