Is Fastboy SS Team Manager All SS (v188.4.10) safe?

Fastboy SS Team Manager ships a hardcoded login token and 4-digit passcode for the vendor's own gocheckin.net booking portal.

The extension hardcodes a static auto-login token and loads it in a hidden background iframe to sign in to apps.gocheckin.net, then hides the token from the address bar afterward. On gocheckin.net booking pages it also auto-fills a hardcoded 4-digit passcode into visible PIN fields. Both values are identical across every install and readable by anyone who unpacks the publicly-listed CRX, but they authenticate to the vendor's own service rather than collecting user data.
