H DID is built on standard OpenID Connect (OIDC). If your tech stack supports OAuth2 or OIDC, you already know how to integrate H DID. No proprietary SDKs required.
- Standard OIDC Discovery endpoint
- Drop-in replacement for passwords
- Works with Passport.js, NextAuth, Auth.js, and more
import { Issuer } from 'openid-client';
// 1. Discover H DID configuration
const hdid = await Issuer.discover('https://auth.h-did.com');
// 2. Initialize the OIDC client
// Note: For SPAs/Mobile, use PKCE without a client_secret
const client = new hdid.Client({
client_id: process.env.HDID_CLIENT_ID,
client_secret: process.env.HDID_CLIENT_SECRET, // Backend only
redirect_uris: ['https://yourapp.com/callback'],
response_types: ['code'],
});
// 3. Generate passwordless auth URL
const authUrl = client.authorizationUrl({
scope: 'openid profile email did',
});Trust & Technology
