The MIT certificate(s) installed on your computer will expire on July 31, 2020. You must renew these certificates by that date to retain access to MIT’s secure web applications, including Atlas, WebSIS, software downloads, and more.
Having a valid certificate is the first step in verifying your identity via MIT’s Touchstone authentication service. The second step is provided through Duo two-factor authentication. To access MIT’s secure online spaces, you need both a valid certificate and a device registered for use with Duo.
How to renew your certificates
You'll need to renew the certificate for each browser on every computer you use. Renewal consists of downloading and installing replacement certificates for your expiring ones.
To install new certificates for Chrome, Internet Explorer, and Safari browsers, CertAid is the quickest and easiest solution. Download and install the latest version of CertAid from the IS&T software grid. Instructions for using CertAid can be found in the IS&T Knowledge Base (KB).
Delete your old certificates
Once you install new certificates, deleting your old ones may help you avoid problems accessing sites and resources. IS&T strongly recommends deleting your old certificates unless you use S/MIME to sign or encrypt emails, in which case you should not delete them.
CertAid will prompt you to delete these old certificates after the new ones have been installed.
Update your Kerberos password
If your Kerberos password is over a year old, you will be required to change it during the certificate renewal process. Choose a strong password and consider using a password manager to save passwords and increase your online security. LastPass Enterprise is available to MIT community members for no charge.
