What this does
The add-on never asks you to paste a key. It shows a short code, opens this page, and waits. Approving here creates an API key on your account, named "Blender sign-in", and hands it to Blender directly. Rigs started from Blender draw on the same credit balance as the web tools.
To sign Blender out, use Sign out in the add-on's Settings panel, or revoke the key on API keys. Either one works on its own.
