@liam-public/browser-webauthn

Passwordless passkey (WebAuthn) client for the browser — the front half of the base CMS's passwordless auth. Pairs with @liam-public/node-webauthn on the server.

Exports

• isPasskeySupported() — feature-detect WebAuthn before offering passkeys.
• registerPasskey(flow, context?) — fetch registration options, run the create() ceremony, POST the attestation to be verified.
• authenticateWithPasskey(flow, context?) — fetch options, run the get() ceremony, POST the assertion. No password is ever sent.

flow is { optionsUrl, verifyUrl, fetch? }.

Usage

import { isPasskeySupported, registerPasskey, authenticateWithPasskey } from '@liam-public/browser-webauthn'

if (isPasskeySupported()) {
  // Sign up / add a passkey (authenticated session for registration):
  await registerPasskey({ optionsUrl: '/auth/passkey/register/options', verifyUrl: '/auth/passkey/register/verify' }, { email })

  // Passwordless sign-in:
  const { token } = await authenticateWithPasskey({ optionsUrl: '/auth/passkey/login/options', verifyUrl: '/auth/passkey/login/verify' })
}

Built on @simplewebauthn/browser.
