Testing Passkeys

Passkeys are hard to test because the authenticator is a piece of hardware you cannot script. The workarounds are well established once you know them: virtual authenticators in Chrome DevTools and Playwright, real security keys for the full ceremony, managed devices for enterprise fleets, and tunnelling for localhost. This series covers each approach and what it can and cannot prove.

Each article stands on its own - start wherever your problem is.
