Does Clerk support passkeys and WebAuthn out of the box? And how much custom work would it take to add phishing-resistant login to a Next.js app?

“Yes. Clerk supports passkeys and WebAuthn natively, including in Next.js.”

“In fact, Clerk's passkey support is close to a turnkey solution: enable it in the dashboard and use its existing authentication components.”

“Clerk handles the underlying WebAuthn registration and authentication ceremonies, including challenge handling and credential verification.”

“No SimpleWebAuthn integration or custom credential database is necessary.”

“If you want complete control over the login experience, Clerk exposes passkey APIs.”

“Pricing: Clerk's documentation currently says passkeys require a paid plan for production use, although they're available in development mode.”

“An important Clerk detail: users currently need another sign-up strategy before they can create their first passkey.”
