TL;DR: Passkey adoption gets less disruptive when browsers surface passkeys and passwords in the same autofill flow, Authsignal says. The sign-in path stays simpler when teams avoid custom branching and keep fallback handling clear.
Editorial analysis by NHI Mgmt Group, based on content published by Authsignal: “How to implement conditional UI for passkeys”.
Key questions
Q: Why does a separate passkey button create adoption friction?
A: A separate button forces the application to decide who should see passkeys and who should not, which often means extra state management or confusing dead ends for users without registered passkeys.
Q: What signs show that a passkey rollout is becoming too complex?
A: If you need user-specific logic to decide when the passkey option appears, or if password fallback starts producing inconsistent screens and error messages, the rollout is drifting away from a clean migration model.
Q: How should teams implement passkeys in customer IAM without breaking existing sign-in journeys?
A: Start with the journeys that create the most friction, then define where passkeys are primary, where fallback is allowed, and which recovery paths remain acceptable.
Practitioner guidance
- Use conditional UI as the default passkey entry pattern Add the WebAuthn autofill token to standard username or password fields so the browser can present passkeys alongside saved passwords without a separate sign-in button.
- Keep the sign-in form simple Use conditional UI with a conventional login flow, because complex multi-step flows can interfere with the browser’s autofill behaviour and reduce passkey visibility.
- Validate the passkey challenge on the server Treat the browser token as the start of authentication, then verify the challenge server-side before creating the session or upgrading the sign-in state.
Bottom line: Conditional UI makes passkey adoption less disruptive by letting browsers present passkeys and passwords in the same autofill flow.

Conditional UI turns passkey adoption into a browser-mediated identity journey, not a custom application decision. That shifts the control boundary from the login page to the browser’s native credential chooser, which reduces the number of places where teams can mis-handle passkey state. The practical consequence is that sign-in governance improves when the browser owns discovery and the application owns validation.
A few things that frame the scale:
- eBay's passkey data shows 55-60% of passkey adoption happens on mobile, against around 20% on desktop.
A question worth separating out:
Q: What should identity teams do when passkeys coexist with password-era workflows?
A: Decide which legacy flows will be retired, which will be time-limited, and which will be prohibited entirely. Then align security, support, and product ownership so the default journey favours passkeys and the exception paths do not reintroduce phishable access.
