# Troubleshooting commit signature verification

You may need to troubleshoot unexpected issues that arise when signing commits locally for verification on GitHub.

* [Checking your commit and tag signature verification status](/en/enterprise-server@3.22/authentication/troubleshooting-commit-signature-verification/checking-your-commit-and-tag-signature-verification-status)

  You can check the verification status of your commit and tag signatures on GitHub.

* [Using a verified email address in your GPG key](/en/enterprise-server@3.22/authentication/troubleshooting-commit-signature-verification/using-a-verified-email-address-in-your-gpg-key)

  When verifying a signature, 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.
