Okta Verify and Certificate-Based Device Trust

SecureW2 enhances Okta’s built-in CA capabilities by providing a more robust and complete Public Key Infrastructure (PKI). While Okta has a basic certificate authority, SecureW2 offers the advanced features needed for a comprehensive Identity Governance program that includes Advanced Security, Real-Time Risk Management, and Compliance

The following article provides the steps to set up CBA with Okta using JoinNow.

Creating an Intermediate CA and Exporting the CA Certificate

To create a new intermediate CA:

  1. Log in to the JoinNow Management Portal.
  2. Navigate to Dynamic PKI > Certificate Authorities.
  3. Click Add Certificate Authority.
  4. In the Basic section, from the Generate CA For drop-down list, select the Device and User Authentication option to authenticate devices and users.
  5. From the Type drop-down list, select Intermediate CA.
  6. From the Certificate Authority drop-down list, select the default Root CA that comes with your organization.
  7. In the Common Name field, enter a common name for the CA certificate. SecureW2 recommends a name that includes “SCEP.”
  8. From the Key Size drop-down list, select 2048 for the CA certificate key pair.
  9. From the Signature Algorithm drop-down list, select the signature algorithm for the certificate signing request. The option available is SHA-256.
  10. In the Validity Period (in years) field, enter the validity period of the CA certificate.
  11. Click Save. The new intermediate CA is generated.
  12. Click the Download link for the intermediate CA created. The downloaded CA will be used to configure external CA in the Okta portal.


    NOTE: The downloaded CA certificate should be converted to PEM format so it can be uploaded to the Okta portal. To convert a .cer file to .pem, use the OpenSSL command-line tool with the command :

    openssl x509 -inform der -in your_certificate.cer -outform pem -out your_certificate.pem

Configuring Okta

The following are the high-level configurations to be made in Okta to configure Secure Web Authentication using joinNow’s PKI Services:

  • Upload External CA in Okta
  • Configuring Authentication Policy in Okta
  • Mapping Applications to the Authentication Policy

Uploading JoinNow Intermediate CA in Okta Portal

  1. In the Okta Admin Console, navigate to Security > Device integrations.
  2. Go to the Certificate authority tab and click Add certificate authority.
  3. In the Add certificate authority dialog box, click Browse files. Select the CA certificate exported from JoinNow portal in PEM format.

    Certificates are uploaded automatically. A message appears if uploads are successful. To view details, click View root certificate chain details.
  4. Click Close.
  5. Go to the Endpoint management tab.
  6. Click Add platform.
  7. Select Desktop (Windows and macOS only) and click Next.
  8. In Configure management attestation, select Use my own certificate authority for the Certificate authority.
  9. Click Save.

Configuring Authentication Policy in Okta

  1. In the Admin Console, navigate to Security > Authentication Policies.
  2. Under app sign-in, click Add a policy.
  3. Enter a name and description for the Authentication Policy. Click Save.
  4. Click on the authentication policy created. Inside the policy page, click Add role.
  5. In the Rule name field, type a name to describe the rule.
  6. From the AND User’s group membership includes drop-down list, select the groups with required users.
  7. In the And Device state is section, click on the Registered option.
  8. In the And Device Management is section, click on the Managed option.
  9. Configure the appropriate THEN conditions to specify how authentication is enforced.
  10. Configure the re-authentication frequency, if needed.
  11. Click Save. The authentication policy will be created successfully.

Mapping Applications to the Authentication Policy

  1. Click on Applications.
  2. Click Add app.
  3. In the search box, enter the name of the required application for which the policy must be mapped to. Click Add.
  4. Applications with the required users and groups can be created in the Applications tab:
