How to Get Computer Accounts

If you are a visitor, or new staff member, welcome! We provide computer account applications using the link below. If you are a short-term visitor and do not need to access UCAR resources, you may be fine with just a wi-fi connection to "UCAR Visitors". On this network, you will be prompted for your email address to gain short-term access.  An email will be sent to you with instructions on how to sign up for longer term access.

If you are needing to access computers and printers within ACOM, you will first need to apply for a CIT Password.   The CIT password is what we use for most of our ACD computer accounts including Email, Windows, and Linux logins.  The UCAS account is for a few internal web pages and the High Performance Storage System (HPSS).  Our form (below) generates passwords which must be renewed after 6 months.   We schedule "password change" events in April and October.

You may also need an authenticator token (such Duo software on your smart phone or a YubiKey device) for:

  • logging in from outside the UCAR network via or using a VPN client
  • ssh'ing to our multi-user Unix servers
  • Accessing CISL supercomputers

Getting authenticator tokens usually take a few days, and the token itself may be delivered to a Systems Administrator from whom you can pick up the device.  To get started, see your System Administrator (listed at ).

For a general overview of our computer resources and policies, take a look at our Computing web pages.

Application Form

The following form first asks you to fill out an "authenticator agreement" and then asks for a current CIT password or authenticator token response to go to a web page which generates a new password for you.  You may use this at any time -- passwords will be good until either April or October, whichever comes first.
