Set up single sign-on (SSO) - Lovable Documentation

Single sign-on (SSO) is available on Business and Enterprise plans and enables secure, centralized authentication across your organization. With SSO, users can access Lovable with one set of credentials, simplifying access management and improving security.

Service provider (SP)-initiated sign-in only: users must start sign-in from Lovable (SP).Identity provider (IdP)-initiated SSO (starting from an IdP dashboard tile) is not supported.

Supported SSO protocols

Lovable supports both OIDC and SAML 2.0 protocols, enabling integration with all major identity providers (IdP) including Okta, Auth0, Microsoft Entra ID (Azure AD), and more.

OpenID Connect (OIDC): recommended; a modern identity layer built on top of OAuth 2.0 that provides identity verification.
SAML (Security Assertion Markup Language) 2.0: XML-based protocol for exchanging authentication and authorization data, widely used in enterprise environments.

Prerequisites

To connect your identity provider to Lovable using OIDC or SAML, you need:

IdP admin access (Okta, Auth0, Microsoft Entra ID, or any other provider you’re using)
Lovable workspace owner or admin role
A verified domain in Lovable

Start SSO setup in Lovable

SSO configuration is a two-way setup between Lovable and your identity provider:

Lovable → IdP: copy Lovable URLs and settings into your IdP app.
IdP → Lovable: copy your IdP’s issuer, metadata, and certificates back into Lovable.

The workspace owner or admin can set up SSO. To start, go to Settings → Workspace → Identity → Add SSO provider, then choose OIDC or SAML.

IdP configuration reference

When you start the SSO provider setup in Lovable, you see:

What to configure in your IdP (for example, app type, scopes, and attribute mappings)

OIDC
SAML

Provider mappingCommon field names across providers:

Redirect URI: Callback URL, Sign-in redirect URI
Issuer/Domain: Issuer URL, Authority, Okta domain, Auth0 domain, Tenant domain
Client credentials: Client ID and Client Secret

Steps

Provide Lovable with your IdP information

In your IdP, copy the following values and enter them in Lovable:

Domain or Issuer URL → Lovable OIDC Issuer URL/Discovery Endpoint
Client ID → Lovable OAuth Client ID/Application ID
Client Secret → Lovable OAuth Client Secret

Provider mappingCommon field names across providers:

ACS URL: Single Sign-On URL, SSO URL, Reply URL, Assertion Consumer Service URL
Audience: SP Entity ID, Audience URI, Identifier
Attribute mapping: Attribute Statements, User Attributes & Claims

Steps

Create a SAML 2.0 application

Configure endpoints

ACS URL: https://auth.lovable.dev/__/auth/handler
Audience / Entity ID: https://auth.lovable.dev/__/auth/handler

Map attributes

Ensure email is included in the SAML assertion. displayName is optional.

Assign users

Troubleshooting

OIDC
SAML

Invalid or mismatched Redirect URI

Ensure the redirect/callback URL exactly matches https://auth.lovable.dev/__/auth/handler in your IdP.

Issuer URL / discovery fails

Use the provider’s OIDC Issuer URL (not just the domain).

For Okta, copy from the Sign-on tab
For Auth0, use your tenant domain.

Email not returned

Grant the email scope and ensure the user account has a primary email.

Authorization flow issues

Use Authorization Code with a confidential client and client secret. Avoid implicit or PKCE-only app types.

Invalid ACS or Audience

Ensure both ACS and Audience/Entity ID exactly match https://auth.lovable.dev/__/auth/handler in your IdP.

Email claim missing

Make sure to map an email claim.For Microsoft Entra ID, map email to user.mail. If user.mail is empty, use user.userprincipalname.

Provider credentials invalid

Paste the correct X.509 certificate. If the certificate rotates, update it in Lovable.

FAQ

I already have an account, but I'm joining a business workspace that uses SSO. How do I log in?

If you created your account using another login method (like email/password, Google, or GitHub), you need to log in that way first. Once you’re logged in, navigate to Settings → Your account → Link SSO. This will link your existing account to your company SSO.

Important: If you attempt to log in with SSO before linking your existing account, you’ll see an error. This is a security measure to prevent unauthorized access. Log in using your original method first to complete the linking process.

Which SSO providers does Lovable support?

Lovable supports the industry-standard OIDC and SAML protocols, so you can integrate with any SSO provider that supports them.

Does Lovable support multiple SSO providers per workspace?

No. A workspace can have one active SSO provider configured at a time.

Can I enforce SSO for my workspace?

Yes. The workspace owner or admin can enable Enforce SSO in Settings → Workspace → Identity and choose the session duration to configure how long users stay signed in before requiring re-authentication (24 hours, 48 hours, or 7 days).This requires all workspace members to use SSO for authentication. External collaborators and invite links will be disabled.

Does Lovable support IdP-initiated SSO?

No. IdP-initiated SSO (starting from an IdP dashboard tile) is not supported.Lovable supports SP-initiated sign-in only. Users must start sign-in from Lovable.

Does Lovable support SCIM or automatic user provisioning?

Lovable supports JIT (just-in-time) provisioning: user accounts are created automatically the first time someone signs in via SSO, and they’re added to your company workspace.You can also set a default role for JIT-created users (admin, editor, or viewer) that will be applied when they join via SSO for the first time.

Your tenant ID is the {tenantId} value used in your SSO login URL:
https://lovable.dev/sso-login/{tenantId}. It matches the SSO login identifier you configured when setting up your SSO provider in Lovable.You can also find it in Settings → Workspace → Identity after you have configured your provider.
