About unlinking your email address
Since an email address can only be associated with a single GitHub account, when you've lost your 2FA credentials and are unable to recover access, unlinking your email address from the locked account allows you to link that email address to a new or existing account. Additionally, linking a previously used commit email address to a new account will connect your commit history to that account. Unless you have chosen to keep your email address private, your account's commit email address is the same as your account's primary email address. See 设置提交电子邮件地址.
注意
The GitHub-provided noreply email address cannot be unlinked from an account. Commits authored with a noreply address cannot be reconnected to a different account.
Be aware that nothing else associated with your 2FA locked account, including your repositories, permissions, and profile, will transfer to your new account.
Unlinking your email address
Unlinking email addresses is only available for accounts with 2FA enabled. If you do not have 2FA enabled, you can sign in and remove your email address from your account settings.
Educational benefits cannot be transferred after an email address is unlinked and associated with a different account. To keep these benefits, you must continue using the original account that was used to apply.
警告
Following these steps will not disable 2FA or provide access to a locked account, but will instead unlink the associated email address so it may be used for a different account. If you cannot regain access to the 2FA locked account, these steps will permanently break the link between the account and the linked email address. Before continuing, be sure you have lost all access to your account. See 丢失 2FA 凭据时恢复帐户.
