App sign-in and API keys

Two entries, one organization

App sign-in (browser, desktop, mobile) is a user’s session. Documents, settings and support live there.

API keys are for scripts, MCP and integrations. They do not replace a person signing in to the interface.

Both paths consume the same organization credits: What are Credits?.
