SDK Authentication

The dypai.auth module provides a complete way to handle user registration, login, and session management. It automatically handles token persistence in localStorage, background token refresh, cross-tab synchronization, and email verification callbacks.

Need help choosing the product flow first?

If you are deciding whether your app should support signup, invitation-only onboarding, or backend-only integrations, read Auth Flows first.

Email & Password

JavaScript

const { data, error } = await dypai.auth.signUp({
  email: 'user@example.com',
  password: 'secure-password',
  full_name: 'John Doe'  // extra fields auto-forwarded to user_metadata
});

if (error) {
  console.error(error.message);
  return;
}

if (data.confirmationRequired) {
  // Email confirmation is enabled — user must verify their email
  showMessage('Check your inbox to confirm your email');
} else {
  // Email confirmation disabled — user is logged in immediately
  console.log('Logged in:', data.user);
}

Email confirmation is enabled by default. When active, signUp() creates the user but does NOT start a session. The user must click the confirmation link sent to their email before they can log in.

Extra fields like full_name, username, or any custom data are automatically merged into user_metadata. You can also pass them explicitly via user_data:

JavaScript

await dypai.auth.signUp({
  email, password,
  user_data: { full_name: 'John Doe', company: 'Acme' }
});

JavaScript

const { data, error } = await dypai.auth.signInWithPassword({
  email: 'user@example.com',
  password: 'secure-password'
});

if (error) {
  // If user hasn't confirmed email, error.status will be 400
  console.error(error.message);
  return;
}

console.log('Logged in:', data.user);

signInWithPassword() will fail with a 400 error if the user hasn't confirmed their email yet. Show a message like "Please confirm your email first" and offer to resend the confirmation email.

Resend Confirmation Email

If a user didn't receive their confirmation email or the link expired:

JavaScript

const { data, error } = await dypai.auth.resendConfirmationEmail('user@example.com');

if (!error) {
  showMessage('Confirmation email resent — check your inbox');
}

Email Verification & Callbacks

When a user clicks a confirmation link, magic link, or password reset link from their email, the auth server redirects back to your app with tokens in the URL hash:

JavaScript

https://your-app.com/#access_token=eyJ...&refresh_token=xxx&type=signup

For private app invitations, use the same callback pattern with type=invite:

JavaScript

https://your-app.com/#access_token=eyJ...&refresh_token=xxx&type=invite

The SDK handles this automatically. On initialization, it:

Checks window.location.hash for auth callback tokens.
If found: fetches user data, establishes the session, and cleans the URL.
Emits the appropriate event: SIGNED_IN or PASSWORD_RECOVERY.

No extra code needed — just listen for auth events:

JavaScript

dypai.auth.onAuthStateChange((event, session) => {
  if (event === 'SIGNED_IN') {
    router.push('/dashboard');
  }
  if (event === 'PASSWORD_RECOVERY') {
    router.push('/reset-password');
  }
});

Invitations (Private Apps)

For B2B/private apps, invitation UX should live in the customer app (not DYPAI dashboard):

Your backend generates an invite link via the auth system (type=invite).
redirect_to must point to a route in the customer app (for example /auth/callback).
That route must be allowed in the auth redirect allowlist.
SDK detects invite callback and emits PASSWORD_RECOVERY.
Show a "Set password" form and call dypai.auth.setPassword(...).

JavaScript

dypai.auth.onAuthStateChange(async (event) => {
  if (event === 'PASSWORD_RECOVERY') {
    await dypai.auth.setPassword('new-secure-password');
  }
});

Passwordless (OTP)

Email OTP

JavaScript

// 1. Send a 6-digit code to the user's email
await dypai.auth.signInWithOtp({
  email: 'user@example.com',
  create_user: true  // auto-register if user doesn't exist
});

// 2. User enters the code
const { data, error } = await dypai.auth.verifyOtp({
  email: 'user@example.com',
  token: '123456',
  type: 'magiclink'  // always 'magiclink' for email OTP
});

Phone (SMS) OTP

JavaScript

// 1. Send a 6-digit code via SMS
await dypai.auth.signInWithOtp({
  phone: '+34600000000',
  create_user: true
});

// 2. User enters the code
const { data, error } = await dypai.auth.verifyOtp({
  phone: '+34600000000',
  token: '123456',
  type: 'sms'  // always 'sms' for phone OTP
});

OTP type must match the flow. Use 'magiclink' for email OTP, 'sms' for phone OTP, and 'signup' for signup confirmation codes. Using the wrong type will cause verification to fail.

OAuth

Redirect users to sign in with their Google, GitHub, or other OAuth accounts:

JavaScript

await dypai.auth.signInWithOAuth('google', {
  redirectTo: 'https://your-app.com/auth/callback',
  scopes: ['email', 'profile']  // optional
});

This redirects the browser to the OAuth provider. When the user returns to your app, the SDK automatically picks up the session from the URL callback.

Password Recovery

JavaScript

// 1. Send a password reset email
await dypai.auth.resetPasswordForEmail('user@example.com');

// 2. User clicks the link in the email → SDK auto-detects the recovery token
dypai.auth.onAuthStateChange(async (event, session) => {
  if (event === 'PASSWORD_RECOVERY') {
    // Show "set new password" form, then:
    const { data, error } = await dypai.auth.updateUser({
      password: 'new-secure-password'
    });
  }
});

Session & User

Get Session

JavaScript

const { data: session, error } = await dypai.auth.getSession();

if (session) {
  console.log('Token:', session.access_token);
  console.log('User:', session.user);
}

getSession() waits for the SDK initialization to complete before responding, so it's safe to call on page load without race conditions.

Get Current User

JavaScript

const { data: user, error } = await dypai.auth.getUser();
// or the shorthand alias:
const { data: user, error } = await dypai.me();

Quick Sync Check

JavaScript

if (dypai.auth.isLoggedIn()) {
  // User has an active session
}

isLoggedIn() is synchronous and may return false during SDK initialization. For a reliable check at startup, use await dypai.auth.getSession() or onAuthStateChange instead.

User Object and Role

The SDK normalizes the user object so your app role is always accessible as user.role:

JavaScript

const { data: user } = await dypai.auth.getUser();

user.id          // User UUID
user.email       // email
user.role        // "admin", "editor", "viewer", etc. — your app role
user.confirmed_at // null if email not confirmed

user.role is always your application role, not the auth engine's internal role. Internally, the auth server stores the role in app_metadata.role. The SDK automatically extracts it to user.role so you don't need to access user.app_metadata.role manually. This applies to both dypai.auth.getUser() and dypai.users.list().

User Profile

JavaScript

// Read current user
const user = dypai.auth.user;
console.log(user.email, user.confirmed_at);

// Update user metadata
await dypai.auth.updateUser({
  data: {
    full_name: 'John Doe',
    avatar_url: 'https://example.com/avatar.jpg'
  }
});

Auth State Listener

React to authentication changes in real time:

JavaScript

const { data: { subscription } } = dypai.auth.onAuthStateChange((event, session) => {
  switch (event) {
    case 'INITIAL_SESSION':
      // Fired on SDK init — session recovered from storage (or null)
      break;
    case 'SIGNED_IN':
      // User logged in (password, OTP, OAuth, or email link callback)
      break;
    case 'SIGNED_OUT':
      // User logged out or session expired
      break;
    case 'TOKEN_REFRESHED':
      // Access token silently refreshed in background
      break;
    case 'USER_UPDATED':
      // Profile or password changed via updateUser()
      break;
    case 'PASSWORD_RECOVERY':
      // User arrived via password reset link — show new password form
      break;
  }
});

// To unsubscribe later:
subscription.unsubscribe();

Sign Out

JavaScript

await dypai.auth.signOut();
