Closes #472 (partially — addresses the gesture verification aspect)

The following tasks have been completed:

  • Modified Web platform tests — normative SHOULD requirement, not testable via WPT (implementation-specific mechanism)

Implementation commitment:

  • WebKit (Bug 312458)
  • Chromium (link to issue)
  • Gecko (link to issue)

Documentation and checks

  • Affects privacy
  • Affects security
  • Pinged MDN
  • Updated Explainer
  • Updated digitalcredentials.dev

Summary

  • Adds a SHOULD-level requirement for user agents to independently verify that the credential request was initiated by a genuine user gesture, using a trusted process rather than solely relying on the content process
  • Defense in depth against compromised renderers presenting the digital credential chooser without actual user activation
