Managing your personal account
You can manage your personal account on GitHub.com. For example, you can manage multiple accounts, convert an account to an organization, or delete an account.
If you use one workstation to contribute to projects for more than one account on GitHub.com, you can modify your Git configuration to simplify the contribution process.
If you have separate accounts for work and personal use, you can merge the accounts.
You can convert your personal account into an organization. This allows more granular permissions for repositories that belong to the organization.
If you use your account on GitHub for both personal and work purposes, there are a few things to keep in mind when you leave your company or organization.
You can remove the connection between your email address and a locked account. The email address is then available for you to link it to a new or existing account, maintaining your commit history.
You can delete your personal account on GitHub.com at any time.
