To make onboarding as simple and easy as possible, itopia Labs provides Single Sign-on (SSO) via Google Workspaces. Labs admins and users must use Google Workspace for Education as their identity provider -- other identity providers are currently not supported.
Some school districts use K-12 specific SSO integrations (i.e. ClassLink). Generally, these aren't supported because Google only allows a single SSO provider to be configured at a time.
