Officially, they don't. Google updates the FRP mechanism every few months (Android 14 introduced hardware-backed locks that are nearly impossible to bypass via software). However, repair shops need these tools. It is cheaper for a shop to pay $10/month for a licensed tool (like Chimera or Octoplus) than to refuse service to a customer who lost their receipt.
I notice you’ve mentioned “gsmoneinfo” and “androidfrp verified” — these appear to be references to websites or services that may offer tools or bypass methods for Android Factory Reset Protection (FRP). gsmoneinfo o androidfrp verified
