Auth Token Usage

You can quickly revoke Claude Code access via the Claude.ai settings page: https://claude.ai/settings/claude-code

"Manage your authorization tokens" lists each connected session with its scope (e.g. user:inference, user:sessions:claude_code) and when it connected (e.g. "Connected 1 hour ago").
Clicking revoke on a token shows a "Revoke access?" confirmation — this will revoke access for that application; you'll need to reconnect it if you want to use it again.
