# Upgrade to OAuth Security for Your Salesforce External Connections

Increase data security by using OAuth 2.0 authentication with your Salesforce external input and output connectors. The SOAP login() API isn't supported after v64. To maintain data sync, you must upgrade all existing Salesforce external connections to use OAuth before the Winter ‘27 release.

**Where:** This change applies to CRM Analytics in Lightning Experience and Salesforce Classic. CRM Analytics is available for an extra cost in Enterprise, Performance, and Unlimited editions.

**How:**

1. In Salesforce setup, configure an External Client App (ECA) for OAuth authentication.
2. In your Salesforce external connections, select the OAuth authentication type.
3. Add the **Client ID** and **Client Secret** values in the connection settings.

Note Salesforce external input and output connectors using the **Username**, **Password**, and **Service URL** settings cease to function after October 27—31, 2026. Until then, data syncs for existing connections still work with warnings in the job logs. After support ends, the data syncs fail.
