Certificates at MIT

On this page:

Overview

Certificates are your key to secure web services at MIT, such as Atlas, and WebSIS and Stellar. They are a safe way for our web applications to identify you without you needing to type in a username and password. Certificates expire once per year, creating the need to renew them at least this often. They must be installed on each browser for each computer that you plan on using to access certificate-protected sites.

Using CertAid (Recommended)

We strongly recommend using CertAid to configure your certificates for Chrome, Internet Explorer, and Safari. It manages the entire certificate setup procedure, giving you a more reliable installation experience. The setup procedure includes installing the MIT CA as well as your personal certificate, optionally deleting old certificates, and setting the correct identity preferences via a single, graphical application. If you need to retain access to old user certificates, e.g., for access to encrypted mail, you should not delete them.

Without CertAid

  1. Go to MIT's certificate server website to get the certificates.
  2. Enter your Kerberos username, password, and MIT ID, then click Next.
  3. The next page will have settings related to the security key. Leave the default values and click Next.
    Second page of MIT's certificate website
  4. The certificate will be installed by the browser.
    • If on Chrome, a bar at the top of the page will appear saying "Successfully stored client certificate issued by Massachusetts Institute of Technology". This means that the personal certificate from MIT has been installed in your browser.
    • If on Firefox, a popup saying "Your personal certificate has been installed" will appear. Click OK to continue.
  5. Click on the link where the website says "Click to install the MIT Certificate Authority". This will download file called "mitca.crt".
