Campus Wireless Upgrade Project Successfully Completed

As of January 31, 2024, we are pleased to announce the successful completion of the Campus Wireless Upgrade Project. Since its inception in 2017, our dedicated teams have worked diligently to redesign wireless coverage across campus, ensuring it aligns with modern technology requirements.

Key Achievements:

  • 138 Buildings Upgraded: We revamped wireless infrastructure in 138 campus buildings, covering a total of 3.5 million square feet.
  • Access Points Added: Over 2,500 access points were strategically installed, enhancing connectivity.
  • Total Access Points: Our network now boasts a robust 4,000 access points.

We extend our sincere appreciation to the building owners, IMSS Data Networks, Project Management, and Communications Teams, as well as the invaluable support from Caltech's Electric Shop.

MFA March update

Multi-factor authentication (MFA) is a security technology that requires multiple methods of authentication. The goal of MFA is to create a layered defense that makes it more difficult for an unauthorized person to access your account. When you use MFA, you login using your username, password, and a third factor - either a smartphone app (Duo) or a hardware token. Even if your password is compromised your account will remain secure. It is likely that you may already be familiar with MFA for handling personal accounts such as online banking, social media apps, Google, etc. At Caltech multi-factor authentication is already required for certain groups and applications and for new Caltech accounts.


  • One of the easiest and most effective ways to keep your account secure
  • Account remains protected even if password is compromised
  • Quick setup process, simple to use, and free when using the Duo Mobile app

Learn more about Multi-factor authentication (Duo) & Office 365. If you already meet the requirements and are ready to enroll in MFA for Office 365, please review the MFA Self Enrollment page for the next steps.

For questions, review the MFA (Duo) FAQs page or contact the IMSS Help Desk at 626.395.3500,, or (request type: IMSS > Duo/MFA Help).
