Lost UNI (University Network ID) or password
Every Columbia University student, faculty member, and permanent staff member has a unique identifier consisting of their initials plus an arbitrary number. Please visit where you can lookup your UNI, activate your UNI, or get information on how to have your password reset if necessary. If you are still having trouble, contact the CUIT Helpdesk Support Center.

Digital certificates
A digital certificate is a form of electronic identification for computer services, such as Web servers or email servers. Installing digital certificates on your computer will allow you to set up trusted connections with the network services you want to use.

Many ColumbiaWeb services are restricted for a variety of reasons, including licensing and privacy issues. For access to many of these services you must use Netscape 3.0 or later, log in with your CUNIX ID and password, pass through a variety of security screens, and finally log out when finished. Please note that other security measures may be in place that require a different procedure.

The Columbia University Certificate Authority ("CA") enables access to secure Columbia services for several years. Certificates for particular Columbia Web servers, e.g., "www1," expire annually each July 1. Download digital certificates.
