Single Sign-On lets your team sign in to Sim through your company's identity provider instead of managing separate passwords. Sim supports both OIDC and SAML 2.0.
Setup
1. Open SSO settings
Go to Settings → Enterprise → Single Sign-On in your workspace.
2. Choose a protocol
| Protocol | Use when |
|---|---|
| OIDC | Your IdP supports OpenID Connect — Okta, Microsoft Entra ID, Auth0, Google Workspace |
| SAML 2.0 | Your IdP is SAML-only — ADFS, Shibboleth, or older enterprise IdPs |
3. Fill in the form
Fields required for both protocols:
| Field | What to enter |
|---|---|
| Provider ID | A short slug identifying this connection, e.g. okta or azure-ad. Letters, numbers, and dashes only. |
| Issuer URL | The identity provider's issuer URL. Must be HTTPS. |
| Domain | Your organization's email domain, e.g. company.com. Users with this domain will be routed through SSO at sign-in. |
OIDC additional fields:
| Field | What to enter |
|---|---|
| Client ID | The application client ID from your IdP. |
| Client Secret | The client secret from your IdP. |
| Scopes | Comma-separated OIDC scopes. Default: openid,profile,email. |
For OIDC, Sim automatically fetches endpoints (authorization_endpoint, token_endpoint, userinfo_endpoint, jwks_uri) from your issuer's /.well-known/openid-configuration discovery document. You only need to provide the issuer URL.
SAML additional fields:
| Field | What to enter |
|---|---|
| Entry Point URL | The IdP's SSO service URL where Sim sends authentication requests. |
| Identity Provider Certificate | The Base-64 encoded X.509 certificate from your IdP for verifying assertions. |
4. Copy the Callback URL
The Callback URL shown in the form is the endpoint your identity provider must redirect users back to after authentication. Copy it and register it in your IdP before saving.
OIDC providers (Okta, Microsoft Entra ID, Google Workspace, Auth0):
https://sim.ai/api/auth/sso/callback/{provider-id}SAML providers (ADFS, Shibboleth):
https://sim.ai/api/auth/sso/saml2/callback/{provider-id}5. Save and test
Click Save. To test, sign out and use the Sign in with SSO button on the login page. Enter an email address at your configured domain — Sim will redirect you to your identity provider.
Provider Guides
Okta (OIDC)
In Okta (official docs):
- Go to Applications → Create App Integration
- Select OIDC - OpenID Connect, then Web Application
- Set the Sign-in redirect URI to your Sim callback URL:
https://sim.ai/api/auth/sso/callback/okta - Under Assignments, grant access to the relevant users or groups
- Copy the Client ID and Client Secret from the app's General tab
- Your Okta domain is the hostname of your admin console, e.g.
dev-1234567.okta.com
In Sim:
| Field | Value |
|---|---|
| Provider Type | OIDC |
| Provider ID | okta |
| Issuer URL | https://dev-1234567.okta.com/oauth2/default |
| Domain | company.com |
| Client ID | From Okta app |
| Client Secret | From Okta app |
The issuer URL uses Okta's default authorization server, which is pre-configured on every Okta org. If you created a custom authorization server, replace default with your server name.
Microsoft Entra ID (OIDC)
In Azure (official docs):
- Go to Microsoft Entra ID → App registrations → New registration
- Under Redirect URI, select Web and enter your Sim callback URL:
https://sim.ai/api/auth/sso/callback/azure-ad - After registration, go to Certificates & secrets → New client secret and copy the value immediately — it won't be shown again
- Go to Overview and copy the Application (client) ID and Directory (tenant) ID
In Sim:
| Field | Value |
|---|---|
| Provider Type | OIDC |
| Provider ID | azure-ad |
| Issuer URL | https://login.microsoftonline.com/{tenant-id}/v2.0 |
| Domain | company.com |
| Client ID | Application (client) ID |
| Client Secret | Secret value |
Google Workspace (OIDC)
In Google Cloud Console (official docs):
- Go to APIs & Services → Credentials → Create Credentials → OAuth 2.0 Client ID
- Set the application type to Web application
- Add your Sim callback URL to Authorized redirect URIs:
https://sim.ai/api/auth/sso/callback/google-workspace - Copy the Client ID and Client Secret
In Sim:
| Field | Value |
|---|---|
| Provider Type | OIDC |
| Provider ID | google-workspace |
| Issuer URL | https://accounts.google.com |
| Domain | company.com |
| Client ID | From Google Cloud Console |
| Client Secret | From Google Cloud Console |
To restrict sign-in to your Google Workspace domain, configure the OAuth consent screen and ensure your app is set to Internal (Workspace users only) under User type. Setting the app to Internal limits access to users within your Google Workspace organization.
ADFS (SAML 2.0)
In ADFS (official docs):
- Open AD FS Management → Relying Party Trusts → Add Relying Party Trust
- Choose Claims aware, then Enter data about the relying party manually
- Set the Relying party identifier (Entity ID) to your Sim base URL:
https://sim.ai - Add an endpoint: SAML Assertion Consumer Service (HTTP POST) with the URL:
https://sim.ai/api/auth/sso/saml2/callback/adfs - Export the Token-signing certificate from Certificates: right-click → View Certificate → Details → Copy to File, choose Base-64 encoded X.509 (.CER). The
.cerfile is PEM-encoded — rename it to.pembefore pasting its contents into Sim. - Note the ADFS Federation Service endpoint URL (e.g.
https://adfs.company.com/adfs/ls)
In Sim:
| Field | Value |
|---|---|
| Provider Type | SAML |
| Provider ID | adfs |
| Issuer URL | https://sim.ai |
| Domain | company.com |
| Entry Point URL | https://adfs.company.com/adfs/ls |
| Certificate | Contents of the .pem file |
For ADFS, the Issuer URL field is the SP entity ID — the identifier ADFS uses to identify Sim as a relying party. It must match the Relying party identifier you registered in ADFS.
How sign-in works after setup
Once SSO is configured, users with your domain (company.com) can sign in through your identity provider:
- User goes to
sim.aiand clicks Sign in with SSO - They enter their work email (e.g.
alice@company.com) - Sim redirects them to your identity provider
- After authenticating, they are returned to Sim and added to your organization automatically
- They land in the workspace
Users who sign in via SSO for the first time are automatically provisioned and added to your organization — no manual invite required.
Password-based login remains available. Forcing all organization members to use SSO exclusively is not yet supported.
Common Questions
Self-hosted setup
Self-hosted deployments use environment variables instead of the billing/plan check.
Environment variables
# Required
SSO_ENABLED=true
NEXT_PUBLIC_SSO_ENABLED=true
# Required if you want users auto-added to your organization on first SSO sign-in
ORGANIZATIONS_ENABLED=true
NEXT_PUBLIC_ORGANIZATIONS_ENABLED=trueYou can register providers through the Settings UI (same as cloud) or by running the registration script directly against your database.
Script-based registration
Use this when you need to register an SSO provider without going through the UI — for example, during initial deployment or CI/CD automation.
