Change or Open Your Default Org
Salesforce Extensions for VS Code runs commands against the org that you’ve set as your default org for development. In the package development model, your default org is typically a scratch org. In the org development model, it’s typically a sandbox, a Developer Edition (DE) org, or a Trailhead Playground.
To set or change the org that you’re developing against, in the VS Code footer, click the org’s name or the plug icon (). Then, select a different org, or choose SFDX: Set a Default Org to authorize a new org. Or, open the Command Palette and run SFDX: Authorize an Org or SFDX: Create a Default Scratch Org.
To open your default org so that you can test your changes or use declarative tools, click the browser icon () in the footer. Or, open the Command Palette and run SFDX: Open Default Org.
To log out of the default org run SDFX: Log Out from Default Org.
