Addin-only authentication works by registering SPGo as an authenticated Addin that is allowed to make changes to your SharePoint site. This is a common workaround for accessing a SharePont site which has been secured with 2FA. that does not yet support Multi-Factor authentication.

When prompted for credentials, you will need to provide the clientId, clientSecret, and (optionally) the realm value for your Tenant. All of these values are defined when you go through the process of registering SPGo as an Addin on your SharePoint Site.

Additional Configuration

To specify Addin-only authentication, set the authenticationType property to AddinOnly in your spgo.json file, or by selecting the “Addin-only” option when configuring your local environment with the SPGO> Configure Workspace command.
