Adding an email address to your GitHub account

GitHub allows you to add as many email addresses to your account as you like. If you set an email address in your local Git configuration, you will need to add it to your account settings in order to connect your commits to your account. For more information about your email address and commits, see Setting your commit email address.

メモ

  • 使い捨てのメールアドレスサービス（一定期間後に期限切れになる一時的なアドレスでメールを受信できるようにしてくれるサービス）からのメールアドレスは検証できません。 メールアドレスをプライベートにしておきたいなら、GitHub が提供する noreply メールアドレスを使ってください。 詳しくは、「Setting your commit email address」をご覧ください。
  • If you're a member of an マネージド ユーザーを含む Enterprise, you cannot make changes to your email address on GitHub. 詳しくは、「GitHub アカウントの種類」をご覧ください。

  1. GitHub で、任意のページの右上隅にある自分のプロフィール写真をクリックしてから、 [設定] をクリックします。

  3. [メール アドレスの追加] にメール アドレスを入力し、 [追加] をクリックします。

Troubleshooting adding an email

If you see an error message when you try to add an email address to your account, you may be experiencing one of the following issues.

Email already in use

If you see the error message Error adding EMAIL: email is already in use, it means the email address is already linked to another GitHub account. An email address can only be associated with one GitHub account at a time.

To use this email with a different account, follow these steps:

  1. Sign in to the account currently linked to the email address and remove it from that account.
  2. If you don’t have access to the account, request a password reset email to recover it. See GitHub アクセス認証情報を更新する.

Email linked to a マネージド ユーザー アカウント

If the email address that you are trying to add is provided to you by your organization, you may see the Error adding EMAIL: email is already in use error when your organization has created a マネージド ユーザー アカウント for you in their マネージド ユーザーを含む Enterprise.

Reach out to your site administrator or internal IT helpdesk to learn about their deployment of GitHub Enterprise Cloud and how to access the account. You may be able to sign into the GitHub Enterprise Cloud application via the organization's identity provider (IdP).

If you want to use your email address with a personal account, you must sign in to your マネージド ユーザー アカウント and unverify the email in your account settings. The email will remain linked to your マネージド ユーザー アカウント, allowing you to access the account through your organization's IdP.

However, some third-party apps or services may not function properly with a マネージド ユーザー アカウント that has an unverified email address.
