Mojoauth Oidc Hosted Page

Implement MojoAuth OIDC Hosted Page

This skill guides you through implementing the OIDC Authorization Code flow with MojoAuth's Hosted Login Page. MojoAuth provides passwordless authentication (Magic Links, Email OTP, SMS OTP, Social Login, Passkeys) through a single hosted page — no need to build a login UI from scratch.

1. Prerequisites

• Client ID: From the MojoAuth Dashboard.
• Client Secret: From the MojoAuth Dashboard (store securely!).
• Redirect URI: Must be whitelisted in the MojoAuth Dashboard (e.g., http://localhost:3000/callback).
• MojoAuth Domain: Your application's MojoAuth domain (e.g., https://your-app.mojoauth.com).

2. Key OIDC Endpoints

All endpoints are relative to your MojoAuth domain (https://your-app.mojoauth.com):

3. Implementation Steps

Step 1: Configure OIDC Client

Initialize your OIDC client with the credentials above. Use a well-maintained OIDC library for your language. The discovery endpoint will auto-configure all URLs.

Step 2: Redirect to MojoAuth Hosted Login Page

Construct the authorization URL and redirect the user. MojoAuth's Hosted Login Page handles all authentication methods (passwordless email, OTP, social login, passkeys).

• Endpoint: /oauth/authorize
• Params:
  • response_type=code
  • client_id=YOUR_CLIENT_ID
  • redirect_uri=YOUR_REDIRECT_URI
  • scope=openid profile email

Step 3: Handle Callback

On the callback route (e.g., /callback):

1. Extract the code parameter from the query string.
2. Exchange the code for tokens at /oauth2/token.
3. Verify the id_token signature using the JWKS endpoint (/.well-known/jwks.json).

4. Authentication Flow

User clicks "Sign In"
        │
        ▼
Redirect to MojoAuth Hosted Login Page
(https://your-app.mojoauth.com/oauth/authorize)
        │
        ▼
User authenticates via passwordless method
(Magic Link, OTP, Social Login, Passkeys)
        │
        ▼
MojoAuth redirects back with authorization code
        │
        ▼
Your server exchanges code for tokens
(POST /oauth2/token)
        │
        ▼
Verify ID token & create session
