Your user account is your identity on GitHub. Your user account can be a member of any number of organizations, regardless of whether the account is on a free or paid plan.

Use the Available for hire checkbox to view GitHub Jobs posts within GitHub.
You can connect your GitHub identity to third-party applications using OAuth. When authorizing one of these applications, you should ensure you trust the application, review who it's developed by, and review the kinds of information the application wants to access.
