Passkey-first Login

Implement passwordless authentication with biometric login (fingerprint, Face ID, Windows Hello) in just 5 steps

What is Passkey-first Login?

Passkey-first Login replaces traditional passwords with biometric authentication. Users log in with:

• Fingerprint (Touch ID, Android fingerprint)
• Face recognition (Face ID, Windows Hello)
• Hardware security keys (YubiKey, etc.)

Benefits:

• 93% login success rate (FIDO Alliance, 2025)
• 3x faster login compared to passwords
• Zero password fatigue for users
• Phishing-resistant authentication

Integration Steps

Quick start

CDN: add webworker.js in HTML, then use transcodes globally.

npm: npm i @bigstrider/transcodes-sdk, then await init({ projectId }) and named imports.

// After SDK load (CDN: transcodes — npm: import { openAuthLoginModal, on } from '…')
const result = await transcodes.openAuthLoginModal({});
 
if (result.success) {
  const member = result.payload[0].member;
  console.log('Welcome!', member?.email);
}
 
transcodes.on('AUTH_STATE_CHANGED', (payload) => {
  if (payload.isAuthenticated) {
    console.log('Member signed in:', payload.member?.email);
  }
});
