Overview

Certain web applications at MIT require authentication using a personal certificate rather than Touchstone. Install a personal certificate in each web browser you use to access a site requiring certificate authentication. Personal certificates expire every year on July 30.

Get Certificates

If you have not changed your password in the past year, you will need to do so before you can get certificates. Certaid will give you an error saying you're not logged in if you need to update your password.

If your Windows computer is on the MIT domain and you are not on campus, please see: Remote Domain Computers and Password Changes.

Using CertAid (Windows and Mac)

IS&T strongly recommends using CertAid to configure your certificates for Chrome, Safari, and Firefox 90 and above. CertAid manages the entire certificate setup procedure, giving you a more reliable installation experience. The setup procedure includes installing the MIT CA (Certificate Authority) as well as your personal certificate, optionally deleting old certificates, and setting the correct identity preferences via a single, graphical application.

CertAid does not run on mobile devices (i.e., iOS and Android devices)
Windows
  • Edge, Chrome, and Firefox 90+: CertAid 2.2.6 for Windows
    Microsoft Edge needs to at least be installed on the Windows machine in order to fully run.
MacOS X

Deleting Old Certificates

IS&T Strongly Recommends Deleting Your Old/Expired Certificates
Old certificates can confuse browsers and web-sites causing them to fail to authenticate you properly with your active certificates. The easiest way is to use Certaid (see above).

If you need to retain access to old user certificates, e.g., for access to encrypted mail, you should export them from your browser and save them for use with your legacy items.
