You can change several settings for your personal account, including changing your username, making your organization membership visible, and authorizing third-party applications. You can also delete your account.
Changing your GitHub username
You can change your GitHub Enterprise username at any time.
Deleting your user account
You can delete your GitHub Enterprise user account at any time. Before you do so, you should hand over the reins of any organizations you might own.
What's the difference between user and organization accounts?
Your user account is your identity on your GitHub Enterprise instance. Your user account can be a member of any number of organizations, regardless of whether the account is on a free or paid plan.
Publicizing or hiding organization membership
If you'd like to tell the world which organizations you belong to, you can display the avatars of the organizations on your profile.
Permission levels for a user account repository
A repository owned by a user account has two permission levels: the repository owner and collaborators.
What happens when I change my username?
When you change your GitHub Enterprise username, most references to your repositories under the old username automatically change to the new username. However, some links to your profile won't automatically redirect.
Connecting with third-party applications
You can connect your GitHub Enterprise 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.
