1import { Auth } from '@zalter/identity-js';
3// Initialize Zalter Auth client
4const auth = new Auth({
5  projectId: process.env.ZALTER_PROJECT_ID
8// Begin user authentication
9await auth.signInWithCode('start', { email });
11// Finalize using passcode from email
12await auth.signInWithCode('finalize', { code });
14// Get authenticated user
15const user = await auth.getCurrentUser();
Passwordless experience

Authentication with zero passwords

Zalter does not use or store passwords — anywhere. Instead, users achieve authentication with one-time passcodes or magic links plus a private key. Without passwords, threat actors have no credentials to target. You lower costs, reduce complexity and improve your security posture — all while delivering a better experience for customers.
