I need SSO for enterprise customers who use Okta

To support SSO for enterprise customers using Okta, the usual path is to implement SAML 2.0 and/or OIDC with Okta as the Identity Provider (IdP). For B2B enterprise use cases, SAML is still very common; OIDC is simpler if your product and customer setup support it.

Recommended approach

1) Support SAML 2.0 first

This is the most broadly accepted enterprise SSO option for Okta.

You’ll need:

• Your app as the Service Provider (SP)
• Customer’s Okta tenant as the Identity Provider (IdP)

Typical SAML setup includes:

• Entity ID
• ACS URL (Assertion Consumer Service URL)
• Single Logout URL optional
• X.509 certificate from the customer’s Okta app
• NameID / email claim mapping

2) Optionally support OIDC

Okta also supports OpenID Connect well, and it’s easier for modern apps if customers are comfortable with it.

You’ll need:

• Client ID
• Client Secret
• Issuer URL
• Redirect URI
• Scopes like openid email profile

What your enterprise admin flow should look like

Build an admin-facing SSO setup page where customers can:

• Choose Okta
• Enter or upload IdP metadata
• Configure a domain (e.g. acme.com)
• Verify ownership of the domain
• Test login before enabling SSO for all users

Key product features to include

• Domain-based routing: send users with @customer.com to the right IdP
• Just-in-time provisioning: auto-create user accounts on first login
• SCIM provisioning (recommended): allow Okta to create/deactivate users in your app
• Role mapping: map Okta groups to app roles if needed
• SSO fallback: allow admin recovery if IdP is misconfigured

Okta-specific setup steps

For SAML in Okta, the customer usually:

1. Creates a SAML 2.0 app integration
2. Sets your ACS URL and Entity ID
3. Uploads your certificate or metadata
4. Assigns users/groups
5. Gives you the IdP metadata XML or endpoints

For OIDC:

1. Creates an OIDC app integration
2. Sets redirect URIs
3. Shares client credentials and issuer details
4. Assigns users/groups

Security considerations

• Require signed assertions
• Validate audience, issuer, timestamps, and certificate
• Enforce email/domain matching
• Support certificate rotation
• Log SSO events for auditability

If you want the fastest path

A common enterprise-ready stack is:

• SAML SSO
• SCIM provisioning
• Domain discovery
• Admin test flow
