--- title: Using a verified email address in your GPG key intro: 'When verifying a signature, {% data variables.product.github %} checks that the committer or tagger email address matches an email address from the GPG key''s identities and is a verified email address on the user''s account. This ensures that the key belongs to you and that you created the commit or tag.' redirect_from: - /articles/using-a-verified-email-address-in-your-gpg-key - /github/authenticating-to-github/using-a-verified-email-address-in-your-gpg-key - /github/authenticating-to-github/troubleshooting-commit-signature-verification/using-a-verified-email-address-in-your-gpg-key versions: fpt: '*' ghes: '*' ghec: '*' topics: - Identity - Access management shortTitle: Use verified email in GPG key --- {% ifversion fpt or ghec %} If you need to verify your GitHub email address, see [AUTOTITLE](/account-and-profile/setting-up-and-managing-your-personal-account-on-github/managing-email-preferences/verifying-your-email-address). {% endif %}If you need to update or add an email address to your GPG key, see [AUTOTITLE](/authentication/managing-commit-signature-verification/associating-an-email-with-your-gpg-key). Commits and tags may contain several email addresses. For commits, there is the author — the person who wrote the code — and the committer — the person who added the commit to the tree. When signing a commit with Git, whether it be during a merge, cherry-pick, or normal `git commit`, the committer email address will be yours, even if the author email address isn't. Tags are more simple: The tagger email address is always the user who created the tag. If you need to change your committer or tagger email address, see [AUTOTITLE](/account-and-profile/setting-up-and-managing-your-personal-account-on-github/managing-email-preferences/setting-your-commit-email-address). ## Further reading * [AUTOTITLE](/authentication/managing-commit-signature-verification/about-commit-signature-verification)
