Yeah great your PIN is a keyboard walk, but mine sounds way better! This is the top 20 from the Amitay 4-digit PIN dataset. Audio 🔊 on 👂

Got nerd sniped by this:
#PIN #Password #DTMF
While we are at it, these most common words you can create from PINs. Image
... and if you observe hundreds of people entering their PIN the heatmap would look like this.

Forgot to mention that there was a LEGO robot involved in this research 🤓

Happy to share our latest research on #FIDO2 password-less authentication using biometric #WebAuthn, with Leona Lassak, Annika Hildebrandt, and Blase Ur.

Preprint at bottom of thread. Paper to appear at @USENIXSecurity 2021. cc: @FIDOAlliance #usesec21

Users hate passwords; #WebAuthn could render them obsolete. But hardware security keys (YubiKeys) are inconvenient. Fortunately, end users can also use their phones as #FIDO2 authenticators. The user authorizes each sign in using their usual unlock mechanism (biometric, PIN).
Using your fingerprint to sign into a website is new to most end users. Our research focused on users' initial encounters with biometric WebAuthn. Many will encounter WebAuthn for the first time via a small notification on a website encouraging them to adopt the technology.
