Passkey Scanner
Summary: PortSwigger's BApp Store lists a Burp Suite extension called Passkey Scanner, authored by Alex Cowperthwaite at version 1.0 and last updated 16 January 2024, that recognizes and scans Passkey (WebAuthn) protocols and detects security issues. The listing says the extension contains scan checks for those vulnerabilities, with further detail deferred to its GitHub repository, and notes that extensions are written by third-party users of Burp with no warranty from PortSwigger.
Key Takeaway: Passkeys are being pitched as the phishing-resistant replacement for passwords, and this listing shows third-party scan checks for WebAuthn exist as of version 1.0 in January 2024 - meaning the implementation flaws around passkeys are already catalogued and testable by anyone running Burp.
