If you haven’t set up your authentication to an external data system in My Settings, you’re prompted to authenticate the first time you try to access an external system in Salesforce. Click the link or button to complete most of the authentication automatically.

- If you are connecting to Box, Google Drive, SharePoint Online, or OneDrive for Business: Select **OAuth 2.0** as the authentication protocol.
- When you see a message requesting permission for Salesforce to access information from your external system, click **Allow**.
- After the authentication process has finished, you are redirected to Salesforce.
