Rather than building custom integrations for every identity provider—such as Okta, Entra ID, or JumpCloud—and managing the detailed configuration of OIDC and SAML protocols, there are more scalable approaches available.
See a walkthrough of the integration
Review the authentication sequence After your customer's identity provider verifies the user, Scalekit forwards the authentication response directly to your application. You receive the verified identity claims and handle all subsequent user management—creating accounts, managing sessions, and controlling access—using your own systems. ![Diagram showing the SSO authentication flow: User initiates login → Scalekit handles protocol translation → Identity Provider authenticates → User gains access to your application](@/assets/docs/sso-quickstart/1.png) This approach gives you maximum flexibility to integrate SSO into existing authentication architectures while offloading the complexity of SAML and OIDC protocol handling to Scalekit.
Modular SSO is designed for applications that maintain their own user database and session management. This lightweight integration focuses solely on identity verification, giving you complete control over user data and authentication flows. Choose Modular SSO when you: - Want to manage user records in your own database - Prefer to implement custom session management logic - Need to integrate SSO without changing your existing authentication architecture - Already have existing user management infrastructure **Using Full stack auth?:** [Full stack auth](/authenticate/fsa/quickstart/) includes SSO functionality by default.

Go to Dashboard > Authentication > General 2. Under "Full-Stack Auth" section, click "Disable Full-Stack Auth" Now you're ready to start integrating SSO into your app! Next, we'll cover how to use the SDK to authenticate users. 2. ## Set up Scalekit Use the following instructions to install the SDK for your technology stack. Configure your environment with API credentials. Navigate to **Dashboard > Developers > Settings > API credentials** and copy these values to your `.env` file: ```sh showLineNumbers=false title=".env" SCALEKIT_ENVIRONMENT_URL= # Example: https://acme.scalekit.dev or https://auth.acme.com (if custom domain is set) SCALEKIT_CLIENT_ID= # Example: skc_1234567890abcdef SCALEKIT_CLIENT_SECRET= # Example: test_abcdef1234567890 ``` 3. ## Redirect the users to their enterprise identity provider login page Create an authorization URL to redirect users to Scalekit's sign-in page. Use the Scalekit SDK to construct this URL with your redirect URI and required scopes. ```javascript showLineNumbers wrap title="authorization-url.js" collapse={1-8} {"Generates URL to customer's identity provider for SSO login": 28-29} import { Scalekit } from '@scalekit-sdk/node'; const scalekit = new ScalekitClient( '', // Your Scalekit environment URL '', // Unique identifier for your app '', ); const options = {}; // Specify which SSO connection to use (choose one based on your use case) // These identifiers are evaluated in order of precedence: // 1. connectionId (highest precedence) - Use when you know the exact SSO connection options['connectionId'] = 'conn_15696105471768821'; // 2. organizationId - Routes to organization's SSO (useful for multi-tenant apps) // If org has multiple connections, the first active one is selected options['organizationId'] = 'org_15421144869927830'; // 3. loginHint (lowest precedence) - Extracts domain from email to find connection // Domain must be registered to the organization (manually via Dashboard or through admin portal during enterprise onboarding) options['loginHint'] = 'user@example.com'; // redirect_uri: Your callback endpoint that receives the authorization code // Must match the URL registered in your Scalekit dashboard const redirectUrl = 'https://your-app.com/auth/callback'; const authorizationURL = scalekit.getAuthorizationUrl(redirectUrl, options); // Redirect user to this URL to begin SSO authentication ``` ```python showLineNumbers wrap title="authorization_url.py" collapse={1-8} {"Generates URL to customer's identity provider for SSO login": 28-32} from scalekit import ScalekitClient, AuthorizationUrlOptions scalekit = ScalekitClient( '', # Your Scalekit environment URL '', # Unique identifier for your app '' ) options = AuthorizationUrlOptions() # Specify which SSO connection to use (choose one based on your use case) # These identifiers are evaluated in order of precedence: # 1. connection_id (highest precedence) - Use when you know the exact SSO connection options.connection_id = 'conn_15696105471768821' # 2. organization_id - Routes to organization's SSO (useful for multi-tenant apps) # If org has multiple connections, the first active one is selected options.organization_id = 'org_15421144869927830' # 3. login_hint (lowest precedence) - Extracts domain from email to find connection # Domain must be registered to the organization (manually via Dashboard or through admin portal during enterprise onboarding) options.login_hint = 'user@example.com' # redirect_uri: Your callback endpoint that receives the authorization code # Must match the URL registered in your Scalekit dashboard redirect_uri = 'https://your-app.com/auth/callback' authorization_url = scalekit_client.get_authorization_url( redirect_uri=redirect_uri, options=options ) # Redirect user to this URL to begin SSO authentication ``` ```go showLineNumbers title="authorization_url.go" collapse={1-11} {"Generates URL to customer's identity provider for SSO login": 31-36} import ( "github.com/scalekit-inc/scalekit-sdk-go" ) func main() { scalekitClient := scalekit.NewScalekitClient( "", // Your Scalekit environment URL "", // Unique identifier for your app "" ) options := scalekitClient.AuthorizationUrlOptions{} // Specify which SSO connection to use (choose one based on your use case) // These identifiers are evaluated in order of precedence: // 1.

Users verify their identity through the authentication policies set by their organization's administrator. Post successful verification, the user profile is [normalized](/sso/guides/user-profile-details/) and sent to your app. For details on how Scalekit determines which SSO connection to use, refer to the [SSO identifier precedence rules](/sso/guides/authorization-url/#parameter-precedence). 4. ## Handle IdP-initiated SSO When users start the login process from their identity provider's portal (rather than your application), this is called IdP-initiated SSO. Scalekit converts these requests to secure SP-initiated flows automatically. Your initiate login endpoint receives an `idp_initiated_login` JWT parameter containing the user's organization and connection details. Decode this token and generate a new authorization URL to complete the authentication flow securely. ```sh showLineNumbers=false wrap https://yourapp.com/login?idp_initiated_login= ``` Configure your initiate login endpoint in [Dashboard > Authentication > Redirects](/guides/dashboard/redirects/#initiate-login-url) ```javascript wrap title="handle-idp-initiated.js" collapse={3-7} // Your initiate login endpoint receives the IdP-initiated login token const { idp_initiated_login, error, error_description } = req.query; if (error) { return res.status(400).json({ message: error_description }); } // When users start login from their IdP portal, convert to SP-initiated flow if (idp_initiated_login) { // Decode the JWT to extract organization and connection information const claims = await scalekit.getIdpInitiatedLoginClaims(idp_initiated_login); const options = { connectionId: claims.connection_id, // Specific SSO connection organizationId: claims.organization_id, // User's organization loginHint: claims.login_hint, // User's email for context state: claims.relay_state // Preserve state from IdP }; // Generate authorization URL and redirect to complete authentication const authorizationURL = scalekit.getAuthorizationUrl( 'https://your-app.com/auth/callback', options ); return res.redirect(authorizationURL); } ``` ```python title="handle_idp_initiated.py" collapse={5-8} # Your initiate login endpoint receives the IdP-initiated login token idp_initiated_login = request.args.get('idp_initiated_login') error = request.args.get('error') error_description = request.args.get('error_description') if error: raise Exception(error_description) # When users start login from their IdP portal, convert to SP-initiated flow if idp_initiated_login: # Decode the JWT to extract organization and connection information claims = await scalekit.get_idp_initiated_login_claims(idp_initiated_login) options = AuthorizationUrlOptions() options.connection_id = claims.get('connection_id') # Specific SSO connection options.organization_id = claims.get('organization_id') # User's organization options.login_hint = claims.get('login_hint') # User's email for context options.state = claims.get('relay_state') # Preserve state from IdP # Generate authorization URL and redirect to complete authentication authorization_url = scalekit.get_authorization_url( redirect_uri='https://your-app.com/auth/callback', options=options ) return redirect(authorization_url) ``` ```go title="handle_idp_initiated.go" collapse={5-9,30-37} // Your initiate login endpoint receives the IdP-initiated login token idpInitiatedLogin := r.URL.Query().Get("idp_initiated_login") errorDesc := r.URL.Query().Get("error_description") if errorDesc != "" { http.Error(w, errorDesc, http.StatusBadRequest) return } // When users start login from their IdP portal, convert to SP-initiated flow if idpInitiatedLogin != "" { // Decode the JWT to extract organization and connection information claims, err := scalekitClient.GetIdpInitiatedLoginClaims(r.Context(), idpInitiatedLogin) if err != nil { http.Error(w, err.Error(), http.StatusInternalServerError) return } options := scalekit.AuthorizationUrlOptions{ ConnectionId: claims.ConnectionID, // Specific SSO connection OrganizationId: claims.OrganizationID, // User's organization LoginHint: claims.LoginHint, // User's email for context } // Generate authorization URL and redirect to complete authentication authUrl, err := scalekitClient.GetAuthorizationUrl( "https://your-app.com/auth/callback", options ) if err != nil { http.Error(w, err.Error(), http.StatusInternalServerError) return } http.Redirect(w, r, authUrl.String(), http.StatusFound) } ``` ```java title="HandleIdpInitiated.java" // Your initiate login endpoint receives the IdP-initiated login token @GetMapping("/login") public RedirectView handleInitiateLogin( @RequestParam(required = false, name = "idp_initiated_login") String idpInitiatedLoginToken, @RequestParam(required = false) String error, @RequestParam(required = false, name = "error_description") String errorDescription, HttpServletResponse response) throws IOException { if (error != null) { response.sendError(HttpStatus.BAD_REQUEST.value(), errorDescription); return null; } // When users start login from their IdP portal, convert to SP-initiated flow if (idpInitiatedLoginToken != null) { // Decode the JWT to extract organization and connection information IdpInitiatedLoginClaims claims = scalekit .authentication() .getIdpInitiatedLoginClaims(idpInitiatedLoginToken); if (claims == null) { response.sendError(HttpStatus.BAD_REQUEST.value(), "Invalid token"); return null; } AuthorizationUrlOptions options = new AuthorizationUrlOptions(); options.setConnectionId(claims.getConnectionID()); // Specific SSO connection options.setOrganizationId(claims.getOrganizationID()); // User's organization options.setLoginHint(claims.getLoginHint()); // User's email for context // Generate authorization URL and redirect to complete authentication String authUrl = scalekit .authentication() .getAuthorizationUrl("https://your-app.com/auth/callback", options) .toString(); response.sendRedirect(authUrl); return null; } return null; } ``` This approach provides enhanced security by converting IdP-initiated requests to standard SP-initiated flows, protecting against SAML assertion theft and replay attacks.

Your application exchanges this code for the user's profile information and session tokens. 1. Add a callback endpoint in your application (typically `https://your-app.com/auth/callback`) 2. [Register](/guides/dashboard/redirects/#allowed-callback-urls) it in your Scalekit dashboard > Authentication > Redirect URLS > Allowed Callback URLs In authentication flow, Scalekit redirects to your callback URL with an authorization code. Your application exchanges this code for the user's profile information. ```javascript showLineNumbers wrap title="Fetch user profile" {17} // Extract authentication parameters from the callback request const { code, error, error_description, idp_initiated_login, connection_id, relay_state } = req.query; if (error) { // Handle authentication errors returned from the identity provider } // Recommended: Process IdP-initiated login flows (when users start from their SSO portal) const result = await scalekit.authenticateWithCode(code, redirectUri); const userEmail = result.user.email; // Create a session for the authenticated user and grant appropriate access permissions ``` ```py showLineNumbers title="Fetch user profile" # Extract authentication parameters from the callback request code = request.args.get('code') error = request.args.get('error') error_description = request.args.get('error_description') idp_initiated_login = request.args.get('idp_initiated_login') connection_id = request.args.get('connection_id') relay_state = request.args.get('relay_state') if error: raise Exception(error_description) # Recommended: Process IdP-initiated login flows (when users start from their SSO portal) result = scalekit.authenticate_with_code(code, '') # Access normalized user profile information user_email = result.user.email # Create a session for the authenticated user and grant appropriate access permissions ``` ```go title="Fetch user profile" // Extract authentication parameters from the callback request code := r.URL.Query().Get("code") error := r.URL.Query().Get("error") errorDescription := r.URL.Query().Get("error_description") idpInitiatedLogin := r.URL.Query().Get("idp_initiated_login") connectionID := r.URL.Query().Get("connection_id") relayState := r.URL.Query().Get("relay_state") if error != "" { // Handle authentication errors returned from the identity provider } // Recommended: Process IdP-initiated login flows (when users start from their SSO portal) result, err := scalekitClient.AuthenticateWithCode(r.Context(), code, redirectUrl) if err != nil { // Handle token exchange or validation errors } // Access normalized user profile information userEmail := result.User.Email // Create a session for the authenticated user and grant appropriate access permissions ``` ```java showLineNumbers title="Fetch user profile" // Extract authentication parameters from the callback request String code = request.getParameter("code"); String error = request.getParameter("error"); String errorDescription = request.getParameter("error_description"); String idpInitiatedLogin = request.getParameter("idp_initiated_login"); String connectionID = request.getParameter("connection_id"); String relayState = request.getParameter("relay_state"); if (error != null && !error.isEmpty()) { // Handle authentication errors returned from the identity provider return; } // Recommended: Process IdP-initiated login flows (when users start from their SSO portal) try { AuthenticationResponse result = scalekit.authentication().authenticateWithCode(code, redirectUrl); String userEmail = result.getIdTokenClaims().getEmail(); // Create a session for the authenticated user and grant appropriate access permissions } catch (Exception e) { // Handle token exchange or validation errors } ``` The `result` object ```js title="Validate tokens" // Validate and decode the ID token from the authentication result const idTokenClaims = await scalekit.validateToken(result.idToken);

Test all three scenarios before deploying to production. Your environment includes a pre-configured test organization (found in **Dashboard > Organizations**) with domains like `@example.com` and `@example.org` for testing. Pass one of the following connection selectors in your authorization URL: - Email address with `@example.com` or `@example.org` domain - Test organization's connection ID - Organization ID This opens the SSO login page (IdP Simulator) that simulates your customer's identity provider login experience. ![IdP Simulator](@/assets/docs/manual/fundamentals/testing-sso/with-idp-simulator/2.1.png) For detailed testing instructions and scenarios, see our [Complete SSO testing guide](/sso/guides/test-sso/) 7. ## Set up SSO with your existing authentication system Many applications already use an authentication provider such as Auth0, Firebase, or AWS Cognito. To enable single sign-on (SSO) using Scalekit, configure Scalekit to work with your current authentication provider. 7. ## Onboard enterprise customers Enable SSO for your enterprise customers by creating an organization in Scalekit and providing them access to the Admin Portal. Your customers configure their identity provider settings themselves through a self-service portal. **Create an organization** for your customer in [Dashboard > Organizations](https://app.scalekit.com/organizations), then provide Admin Portal access using one of these methods: Generate a secure link your customer can use to access the Admin Portal: ```javascript showLineNumbers=false title="generate-portal-link.js" // Generate a one-time Admin Portal link for your customer const portalLink = await scalekit.organization.generatePortalLink( 'org_32656XXXXXX0438' // Your customer's organization ID ); // Share this link with your customer's IT admin via email or messaging // Example: '/magicLink/8930509d-68cf-4e2c-8c6d-94d2b5e2db43 console.log('Admin Portal URL:', portalLink.location); ``` Send this link to your customer's IT administrator through email, Slack, or your preferred communication channel. They can configure their SSO connection without any developer involvement. Embed the Admin Portal directly in your application using an iframe: ```javascript showLineNumbers=false title="embed-portal.js" // Generate a secure portal link at runtime const portalLink = await scalekit.organization.generatePortalLink(orgId); // Return the link to your frontend to embed in an iframe res.json({ portalUrl: portalLink.location }); ``` ```html showLineNumbers=false title="admin-settings.html" ``` Customers configure SSO without leaving your application, maintaining a consistent user experience. Listen for UI events from the embedded portal to respond to configuration changes, such as when SSO is enabled or the session expires. See the [Admin portal UI events reference](/reference/admin-portal/ui-events/) for details on handling these events. Learn more: [Embedded Admin Portal guide](/guides/admin-portal/#embed-the-admin-portal) **Enable domain verification** for seamless user experience. Once your customer verifies their domain (e.g., `@megacorp.org`), users can sign in without selecting their organization. Scalekit automatically routes them to the correct identity provider based on their email domain. **Pre-check SSO availability** before redirecting users. This prevents failed redirects when a user's domain doesn't have SSO configured: ```javascript showLineNumbers=true title="check-sso-availability.js" // Extract domain from user's email address const domain = email.split('@')[1].toLowerCase(); // e.g., "megacorp.org" // Check if domain has an active SSO connection const connections = await scalekit.connections.listConnectionsByDomain({ domain }); if (connections.length > 0) { // Domain has SSO configured - redirect to identity provider const authUrl = scalekit.getAuthorizationUrl(redirectUri, { domainHint: domain // Automatically routes to correct IdP }); return res.redirect(authUrl); } else { // No SSO for this domain - show alternative login methods return showPasswordlessLogin(); } ``` ```python showLineNumbers=true title="check_sso_availability.py" # Extract domain from user's email address domain = email.split('@')[1].lower() # e.g., "megacorp.org" # Check if domain has an active SSO connection connections = scalekit_client.connections.list_connections_by_domain( domain=domain ) if len(connections) > 0: # Domain has SSO configured - redirect to identity provider options = AuthorizationUrlOptions() options.domain_hint = domain # Automatically routes to correct IdP auth_url = scalekit_client.get_authorization_url( redirect_uri=redirect_uri, options=options ) return redirect(auth_url) else: # No SSO for this domain - show alternative login methods return show_passwordless_login() ``` ```go showLineNumbers=true title="check_sso_availability.go" // Extract domain from user's email address parts := strings.Split(email, "@") domain := strings.ToLower(parts[1]) // e.g., "megacorp.org" // Check if domain has an active SSO connection connections, err := scalekitClient.Connections.ListConnectionsByDomain(domain) if err != nil { // Handle error return err } if len(connections) > 0 { // Domain has SSO configured - redirect to identity provider options := scalekit.AuthorizationUrlOptions{ DomainHint: domain, // Automatically routes to correct IdP } authUrl, err := scalekitClient.GetAuthorizationUrl(redirectUri, options) if err != nil { return err } c.Redirect(http.StatusFound, authUrl.String()) } else { // No SSO for this domain - show alternative login methods return showPasswordlessLogin() } ``` ```java showLineNumbers=true title="CheckSsoAvailability.java" // Extract domain from user's email address String[] parts = email.split("@"); String domain = parts[1].toLowerCase(); // e.g., "megacorp.org" // Check if domain has an active SSO connection List connections = scalekitClient .connections() .listConnectionsByDomain(domain); if (connections.size() > 0) { // Domain has SSO configured - redirect to identity provider AuthorizationUrlOptions options = new AuthorizationUrlOptions(); options.setDomainHint(domain); // Automatically routes to correct IdP String authUrl = scalekitClient .authentication() .getAuthorizationUrl(redirectUri, options) .toString(); return new RedirectView(authUrl); } else { // No SSO for this domain - show alternative login methods return showPasswordlessLogin(); } ``` This check ensures users only see SSO options when available, improving the login experience and reducing confusion. --- ## More Scalekit documentation | Resource | What it contains | When to use it | |----------|-----------------|----------------| | [/llms.txt](/llms.txt) | Structured index with routing hints per product area | Start here — find which documentation set covers your topic before loading full content | | [/llms-full.txt](/llms-full.txt) | Complete documentation for all Scalekit products in one file | Use when you need exhaustive context across multiple products or when the topic spans several areas | | [sitemap-0.xml](https://docs.scalekit.com/sitemap-0.xml) | Full URL list of every documentation page | Use to discover specific page URLs you can fetch for targeted, page-level answers |
