Most of the "Kintone plugin" market is actually external SaaS that integrates with Kintone. Configuration requires logging into a vendor portal, and you end up managing users and permissions in two systems instead of one.
This is driven by vendor economics. SaaS retention metrics, per-user metering, upsell funnels — these only work when users must log into the vendor's portal regularly. It's not that these vendors don't want to move configuration inside Kintone; it's that doing so would break their revenue architecture.
kinplug was designed outside that model. Configuration happens inside Kintone's native plugin UI. This isn't a feature — it's the category kinplug is trying to define.

Google Workspace admins can technically re-enable basic auth on a per-user basis, but it's not recommended for security reasons.
