GitHub provides a number of account recovery methods including an automated recovery process if you have lost access to your GitHub.com account. If you cannot use any of the provided recovery methods, you have permanently lost access to your account.
You can, however, unlink email addresses from a locked account in order to create a new account or use the email on another existing account.
For security reasons, GitHub Support will not restore access to accounts with two-factor authentication enabled if you lose your two-factor authentication credentials or lose access to your account recovery methods. You must use existing account recovery methods.
GitHub does not support any other means of account recovery, including social or ID verification, by members of GitHub’s staff. This policy is in place to protect your account from unauthorized access through social engineering.
Please contact Support to request removal of a payment method from a locked out account. Remember, GitHub Support will not restore your account if you lose access to your account recovery methods.
If you have lost access to an organization account, you may clone or fork any content that is public and you may be able to request that remaining members of the organization clone or fork any private content.
GitHub Support will not recover the contents of a user or organization account that is locked.
