Important Single Sign-On Security Verification Changes

Dear Bruin Community:

In alignment with evolving cybersecurity best practices, UCLA is strengthening protections around how you sign in to campus systems. 

Beginning April 28, obsolete and less secure multi-factor authentication (MFA) methods, including SMS/text message passcodes and phone call-based authentication, will no longer be supported when accessing UCLA systems. 

This message is being sent for general awareness only; users who are directly impacted by this change have already been notified individually and provided guidance on next steps.

These updates are part of UCLA’s ongoing efforts to strengthen cybersecurity, reduce the risk of unauthorized access, and help protect personal data while keeping campus systems secure and reliable.

Please note: If you are a UCLA Health faculty or staff member, this change does not impact you, and no action is required.

What to Know

  • Effective April 28, UCLA will no longer support SMS/text message passcodes or phone call–based multi-factor authentication for systems that require Single Sign-On (SSO).
  • Users who have not transitioned to a supported multi-factor authentication method after April 28 may experience disruption when accessing UCLA systems that require campus MFA.
  • Individuals using SMS/text message passcodes, phone call–based authentication, or an outdated version of the Duo Mobile application will receive follow-up communication with instructions on how to prevent service disruptions.
  • If you already use the Duo Mobile application version 4.85.0 or later for multi-factor authentication on a supported device, you will not be affected by this change.

Support and Resources

  • If this change applies to you, you have already received a direct communication from the Office of the Chief Information Security Officer with guidance on required actions.
  • Additional support and resources are available through the Office of the Chief Information Security Officer website.
  • For questions or assistance, contact the IT Support Center by email (help@it.ucla.edu) or at (310) 267-HELP (4357).

This update reflects UCLA’s ongoing commitment to protecting personal data and maintaining a secure digital environment. 

Thank you for your continued support of these cybersecurity efforts.

Sincerely,

Lucy Avetisyan
Associate Vice Chancellor and Chief Information Officer
