Episode: Lorrie Cranor: Why Security Fails Real People [Afternoon Cyber Tea]

Release Date: December 31, 2025
Host: Dan Johnson
Guest: Dr. Lorrie Cranor, Director of the CyLab Security and Privacy Institute at Carnegie Mellon University

Overview

This episode of Afternoon Cyber Tea features a conversation with Dr. Lorrie Cranor, a globally recognized leader in usable security and privacy. The discussion centers on the persistent "usability gap" in cybersecurity—why security controls often fail for real people—and explores how organizations can design systems that are both secure and user-friendly. Topics include the ongoing challenges with passwords, the state and future of passwordless authentication, user perceptions of privacy, and practical ways for security leaders to integrate behavioral research into their practices.

Key Discussion Points and Insights

1. Why Do Security Controls Fail in Practice?

• Disconnect between Security and Usability
  • Security tools are frequently designed with a sole focus on technological risk, overlooking how real people actually interact with them.
  • “Often the security experts behind the tools are not actually usability or human factors experts. And so without the security people working in partnership with usability people, we often forget to consider the human and the user.”
    — Dr. Lorrie Cranor, 01:31
• CISOs Are Improving but Slowly
  • Many Chief Information Security Officers (CISOs) still neglect user perspectives, though awareness is growing.
  • Usability considerations are a relatively recent development in security leadership.

2. The Ongoing Challenge of Passwords

• Why Can't We Move Beyond Passwords?
  • Industry has yet to find an authentication replacement that is simultaneously:
    • More secure
    • Easier to use
    • Compatible with a wide range of devices and legacy systems
  • “We haven't really found a great solution that is better than passwords that meets all the criteria that we have.”
    — Dr. Lorrie Cranor, 03:04
• Partial Success Stories
  • Biometrics (e.g., facial recognition, fingerprint) have worked well on mobile phones but are not universally applicable or foolproof.

3. Passwordless Authentication and Passkeys

• Current State: More Confusion Than Clarity
  • Both experts and everyday users find passkeys confusing, particularly regarding cross-device access.
  • “If I accept the passkey here and then I want to access this account from another device, what do I do? ... If you run into problems, I'm not going to be able to help you.”
    — Dr. Lorrie Cranor, 04:57
• Biometrics: Simpler, but Not Always Secure
  • Personal anecdote: Early facial recognition on phones was unreliable and even allowed Dr. Cranor’s 6-year-old to unlock her phone (05:54).

4. The Future of Digital Identity

• More Than Authentication
  • Digital identity involves complex needs, like age verification—now under political scrutiny worldwide.
  • Current verification solutions are often privacy-invasive and easily bypassed.
  • Digital wallets could offer a way to prove attributes (like age) without sharing personal data.

5. Shifting User Expectations Around Privacy

• Public Attitudes Have Changed
  • Earlier, users did not believe in or understand the scope of digital tracking; now, there’s general resignation and perceived powerlessness.
  • “They still would like to protect their privacy, but they feel powerless to do anything about it. ... I like the convenience of using all these privacy invasive services and since there's nothing I can do about it, I've just given in.”
    — Dr. Lorrie Cranor, 09:05
• The Illusion of Voluntary Data Sharing
  • People often feel they have no real choice; workarounds to protect privacy are difficult, inconvenient, or expensive.

6. Designing for Transparency and Trust

• Compliance Is Not Enough
  • True trust and usability require more than simply ticking regulatory boxes.
  • Use user studies to observe real behaviors and iteratively improve privacy interfaces.
  • Tips:
    • Keep disclosures simple and context-aware (e.g., show relevant info next to forms).
    • Consolidate privacy settings in one place, but also provide “just in time” notices.
    • Carnegie Mellon’s “Users First” framework helps designers identify and address common usability pitfalls.

7. Applying Behavioral Insights in Security Programs

• Ground Solutions in Research
  • When improving controls (e.g., policies for passwords or access), CISOs should review empirical research and adapt findings to their context.
  • Always conduct small-scale user tests before deploying new controls: “Even having five to ten people test something can actually give you really useful insights.”
    — Dr. Lorrie Cranor, 16:21
• Rapid User Testing
  • Businesses can use pilot groups, focus groups, or even crowd-sourced workers for fast, informative feedback.

8. The Usability “Do-Over” and Successes

• If She Could Redesign One Security Control:
  • Passwords, due to the unrealistic expectation that users will remember so many unique passwords.
• A Tool That Gets Usability Right:
  • Browser encryption (HTTPS): “You don't have to do anything to make it happen. ... That's beautiful.”
    — Dr. Lorrie Cranor, 19:39

9. Optimism for Bridging the Usability Gap

• Tangible Progress
  • Huge growth in usable security research and awareness over the last 25 years.
  • “We're seeing that companies are increasingly trying to make some efforts to find more usable security solutions. There's still a lot of work to be done, but I feel that we actually have made progress.”
    — Dr. Lorrie Cranor, 20:11

Notable Quotes & Memorable Moments

• On Passkeys and User Confusion:
  “Yes, in theory they're more secure and it will eventually be easier, but if you run into problems, I'm not going to be able to help you.”
  — Dr. Cranor, 04:57

• On Perceived Privacy Loss:
  “They don't like it. ... And many of them will say, well, I've really just given up. I like the convenience of using all these privacy invasive services and since there's nothing I can do about it, I've just given in.”
  — Dr. Cranor, 09:05

• On HTTPS as Usability Success:
  “You don't have to do anything to make it happen. ... That's beautiful.”
  — Dr. Cranor, 19:39

• On Progress Over 25 Years:
  “There were like two or three [usable security papers] out there. ... I found a dozen or so [researchers]. ... And I think today... there are thousands of usable security research papers and at least hundreds if not thousands of usable security researchers.”
  — Dr. Cranor, 20:11

Conclusion

Dr. Lorrie Cranor makes clear that real-world security failures largely spring from a lack of user-centric design. By reframing security tools with usability top-of-mind—and validating those tools through targeted user research—organizations can create security controls that don’t just work in theory, but succeed in practice. Progress is being made, though the journey continues, and practical advice for CISOs includes: ground policy choices in research, pilot and test with real users, and simplify both privacy communications and security experiences wherever possible.

“We will solve the usability problems and hopefully the next generation of technology, as we adapt, will continue to help us.”
