# [Limitation] Integration Failures with External Authentication Accounts (Google, SSO, etc.)

> If you log in using Google authentication or SSO, you cannot connect to SaaS services that require ID/password-based integration. This article explains available workarounds.

<h4 id="authentication-error">
  Limitation (Authentication Error)
</h4>

Even with the correct ID and password, an authentication error can occur and the integration can fail.

If you see an authentication error, check whether your situation matches any of the cases below.

#### Unsupported Integration Methods

Integration fails if any condition below applies and this service requires ID/password authentication for that SaaS.

| Situation                   | Description                                                                                                                                                                                                |
| --------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| SSO enforced                | **Login via Single Sign-On (SSO) using SAML or similar** is enforced for the cloud service.                                                                                                                |
| External IdP enforced       | **Login via an external identity provider such as Google Login** is enforced.                                                                                                                              |
| SSO / External IdP enforced | Either pattern above applies, and the service connects to this service **using ID/Password**.<br />Example: The service you want to integrate is Figma, and you log in using Azure AD with Single Sign-On. |

#### Cases Where Connection is Possible

Even in SSO environments, integration is possible if direct ID/password login is also available.

* **SSO is disabled for administrator accounts only**

SSO is enforced for regular users, but direct login is permitted for administrator accounts.

* **External IdP and direct login can be used together**

Even when external IdP integration is the primary method, direct sign-in via ID/password fields may still work.

<h4 id="workaround">
  Workarounds
</h4>

Even when SSO or an external IdP is enforced, integration may still be possible with the steps below.

Prepare an administrator account that can log in with an email address and password.

* Set a password for the account on the cloud service side.
* If you cannot set a password for the account, create a dedicated "system integration account" on the cloud service side. Use that account to set up the integration.
