CNetIDs & Campus Online Access


A CNetID (Chicago Network Identifier) is a username that you select and will use to access most online services provided by the University of Chicago. If your email address at the University of Chicago ends with “” (as in “”) the part of your email address before the “@” is your CNetID (“thatguy” in the example.) This page is intended to explain how CNetIDs are managed within the BSD (Biological Sciences Division).

Access to several systems is provided automatically through your CNetID based on your relationship with the University. This is automatically provisioned when an eligible person successfully registers for a CNetID and password. These services might include email, email forwarding, the (802.1x) wireless networks, the myUChicago portal, Chalk, VPN, WebShare, site-licensed software, etc. Access to some additional systems that use CNetIDs for login is managed by non-automated means and generally is provided on an as-needed basis. To register and claim your CNetID, set your password, reset your forgotten password, manage your account, or for more CNetID information please visit

Eligibility for CNetIDs

You must be in the University student, staff, or faculty records “feed” in order to establish your CNetID. For this reason, certain University affiliates (such as contractors, vendors, etc.) cannot sign up for a CNet online; these must be specifically requested through the Trusted Agent program. The TAG (Trusted AGent) Program is a service that distributes limited authority to departments and divisions to grant access to one or more of the services provided by the University or otherwise requiring a CNetID and password for authentication. Trusted Agents may enter you into the University records. If you are otherwise affiliated with the Biological Sciences Division and need to request a CNetID for someone via a BSD Trusted Agent.

Individuals who are not eligible for permanent CNetID account services, but require them because they will carry out University business for/with the University, or who require services beyond CNetID’s time allotment, may not necessarily receive these services through the TAG Program. These cases will be reviewed on an ad hoc basis. Such cases should be brought to the attention of the TAG Program Administrative Group at The TAG Program Policy and Procedures are located on the web located at More information on how Trusted Agents handle these cases can be found in the Trusted Agents Program Handbook.

Requesting CNetIDs

In order to enter a person’s identity into the University records, the BSD Trusted Agent will need at least the information specified in CNetID Request Questionnaire for BSD Users which is linked here. You may not request a new CNetID from a BSD Trusted Agent for yourself – you must have someone who already has a CNetID request it on your behalf. Please note that we cannot process an initial request via phone – we must have a written record. And unless the CNetID is for someone with only a temporary affiliation with the University, we will also need their Social Security Number. Please do not send social security numbers or other sensitive information via the online form. We will call the phone number listed on the submission form for it.

CNetIDs & Hospital Employees

Hospital and University IT Services have changed policy regarding Hospital (UCM) employees accessing the University VPN, wireless, and other online services. The security and access policy agreed upon by the two requires that UCM employees are typically not granted a CNetID to use University VPN, wireless, and other services. However, some UCM managers and admins may need access to these systems in order to manage the options for their employees. Also, there are some services which are intended to be available to both hospital and university employees (such as Instant Messenger.) So instead, UCM employees may use their UCHAD (University of Chicago Hospitals Active Directory) or BSDAD (Biological Sciences Division Active Directory) credentials to access a number of services. Below are some of the more common examples, but visit the Services Matrix site for further information.


Service Alternatives
Email Address:
Login to departmental/divisional email systems instead: accounts use UCHAD credentials, or accounts use BSDAD credentials. All UCM employees automatically
get UCHAD accounts once HR has a record of their personnel information and employment status. But not every UCM employee
receives a mailbox by default. UCM employees should request a mailbox via a SARF (Systems Access Request Form) – SARF link not accessible from off-campus. BSD departments on the other hand have their own departmental procedures for requesting email access. BSD employees should consult with the departmental administrators for more information.
Wireless Access:
When in the hospital areas, UCM employees should instead login to the ucmc-staff wireless network using their UCHAD or BSDAD credentials. When in a non-hospital area, some staff (primarily IS staff) may also use their UCHAD credentials to login the uchicago-secure wireless network.
Instant Messenger The UCM employee would use their UCHAD username in place of a CNetID to login to the instant messenger system.
Remote Access:
Most clinical and some business applications (including email, fileshares, and MS Office) can be accessed by UCM employees via
the external Citrix-based Clinical Desktop at But if the UCM employee needs to access a workstation, server, or application not available via Citrix, they must submit a SARF requesting their UCHAD be granted access to the Hospital VPN (see for more info.)
Academic Courses:
UCM employees should have their department admin contact Chalk support to confirm authorization. Chalk Support is available via email at or by phone at (773) 702-5800 (option 4.) UCM Employees who have been authorized to use CHALK
should login using their UCHAD credentials instead of a CNet. More information Chalk can be found on the University KnowledgeBase Article on “Chalk”
BSD Procurement:
UCM employees should have their department admin contact Buysite Support to confirm authorization. Buysite Support is
available via e-mail at or by phone at (773) 702-5372. Once authorized to do so, UCM Employees would login to buysite using their UCHAD credentials.
BSD Expenses:
UCM employees should contact their departmental representative at to confirm authorization and contact GEMS support at phone number: (773) 702-5541 and email address: to verify access. Once authorized, the UCM Employee should login to this system using their UCHAD credentials. Contact for more general questions about this an other University financial systems.
BSD Accounting:
UCM employees should have their department admin contact FAS support to confirm authorization. FAS support is reachable via email at Once authorized, the UCM Employee should login to this system using their UCHAD credentials. Contact for more general questions about this an other University financial systems.
Employee Self-
Service: ESS
UCM employees should have their department admin contact ESS support confirm authorization. ESS Support is reachable via email
at Once authorized, the UCM Employee should login to this system using their UCHAD credentials.
Employee Timekeeping:
UCM employees should have their department admin contact UHRM to confirm authorization and then Uchicago Time support to
confirm access. Support is reachable via email at Once authorized, the UCM Employee should login to this system using their UCHAD credentials.
Review: AURA-IRB
To request access to the AURA system, or to request additional roles, UCM employees should follow the instructions here: then simply login using UCHAD credentials. If there are any questions regarding role assignments or other access questions, please email
UCM Employees should have their department/section administrator email the UCMIT Service Desk at requesting access to this system. The Service Desk will need to create a work order for the Academic Research Group (formerly Design & Development) to enable access to that system. Medical Center Employees ineligible for a CNet will use their UCHAD credentials to login to this system.
