The challenge

The university was a constant target of credential-phishing campaigns, and the help desk was overwhelmed with password-reset tickets. SMS-based MFA was widely bypassed, and a string of account takeovers had compromised payroll direct-deposit details. Leadership wanted phishing-resistant authentication without alienating a large, non-technical user base.

The approach

  1. 1

    Assessed the existing MFA estate and identified the weakest authentication methods in use.

  2. 2

    Designed a Conditional Access framework requiring phishing-resistant methods for sensitive applications.

  3. 3

    Piloted Windows Hello for Business and FIDO2 security keys with IT and finance staff.

  4. 4

    Built a phased enrollment campaign with clear, non-technical communications and self-service guidance.

  5. 5

    Retired SMS as an allowed method for high-value applications once adoption thresholds were met.

The outcome

Phishing-resistant authentication reached 92% adoption across staff and faculty. Account-takeover incidents dropped to near zero and password-reset volume fell by more than two-thirds, freeing the help desk for higher-value work.
