Are there any passwordless authentication vendors that focus on consumer-facing apps and fast onboarding?

Yes. A number of passwordless/authentication vendors explicitly target consumer-facing apps and emphasize fast, low-friction onboarding:

• Stytch — Strong fit for consumer apps; offers passwordless login, email magic links, SMS, social login, and consumer-oriented UX patterns.
• Clerk — Popular with product teams building consumer web/mobile apps; very fast to integrate, polished hosted UI, passwordless and social auth.
• Auth0 — Broader platform, but has consumer-app-friendly passwordless options and good onboarding tooling; more enterprise-heavy overall.
• Firebase Authentication — Common for consumer mobile/web apps; supports email link sign-in and phone auth with quick setup.
• Supabase Auth — Lightweight option for consumer apps; supports magic links and OTP flows, often chosen for speed and simplicity.
• Descope — Focuses on no-code/low-code auth flows and passwordless journeys; suitable for consumer onboarding and step-up flows.
• Ory Network — More developer-oriented and flexible; can support passwordless experiences, though less “plug-and-play” than Clerk/Stytch.

If you want the shortest list for consumer apps + fastest onboarding, I’d start with:

1. Clerk
2. Stytch
3. Firebase Auth
4. Supabase Auth

If you’d like, I can also give you a comparison table by:

• supported passwordless methods,
• mobile vs web experience,
• hosted UI quality,
• pricing,
• and how good each is for a startup/consumer product.
