WebISO is the means for Carnegie Mellon web services to securely verify the identity of Carnegie Mellon users. WebISO is a service of Computing Services.

WebISO does not require installation of a plug-in or any other software. However, your browser must be configured to accept cookies. This is the default configuration for all major web browsers. If you have disabled cookies in the past you will need to enable cookie support in your browser to use WebISO. Also, as with all secure web services you will need to have the Carnegie Mellon server certificate installed. This seal indicates the web server uses WebISO.

The first time you visit a WebISO-enabled service, you will be redirected to the login server at http://webiso.andrew.cmu.edu. Your browser will be automatically returned to your original destination once you establish your credentials by entering your User ID and password. Andrew, CS, and ECE accounts are supported, though some services only accept Andrew User IDs.

Important! Until you close your browser or twelve (12) hours pass, your browser will have access to all WebISO-protected resources without the need to answer the user/password challenge.

Please keep this in mind when you are using WebISO - especially when using a computer other than your own! A WebISO-granted web browser is something to take seriously. Note that with some web browsers, like Internet Explorer, you must close all web browsers to end your WebISO session.
