Sanam Ghorbani Lyastani

UX Reseacher / PhD Candidate

CISPA Helmholtz Center for Information Security

I am a UX researcher devoted to making technology more user-friendly. I am wrapping up my Ph.D. journey at the CISPA Helmholtz Center for Information Security, Saarbrücken, Germany. My main research interests during my Ph.D. were passwords, multi-factor authentication, and passwordless authentication with FIDO2/WebAuthn. The results of my works have been published at top-tier scientific conferences like USENIX Security, IEEE S&P, and NDSS. See projects for summaries of my recent works.
