Authentication

Choose how users sign in. Without SSO configured, login falls back to Grengin's hosted authentication proxy.

⚠

Using Grengin's authentication proxy Users will sign in through Grengin's official authentication proxy — not your organization's identity provider. Configure Google or Azure AD above to use your own SSO, or switch anytime from Control Hub → Settings → OAuth without losing your users' data.
