About push protection for secret scanning
The push protection feature of secret scanning helps to prevent security leaks by scanning for secrets before you push changes to your repository. When you enable push protection, secret scanning also checks pushes for high-confidence secrets (those identified with a low false positive rate). Secret scanning lists any secrets it detects so the author can review the secrets and remove them or, if needed, allow those secrets to be pushed. For information on the secrets and service providers supported for push protection, see "Secret scanning patterns."
If you confirm a secret is real, you need to remove the secret from your branch, from all the commits it appears in, before pushing again.
Tip If GitHub blocks a secret that you believe is safe to push, you can allow the secret and specify the reason why it should be allowed. For more information about bypassing push protection for a secret, see "Allowing a blocked secret to be pushed" and "Bypassing push protection for a secret" for the command line and the web UI, respectively.
Resolving a blocked push on the command line
When you attempt to push a supported secret to a repository or organization with secret scanning as a push protection enabled, GitHub will block the push. You can remove the secret from your branch or follow a provided URL to allow the push.
Notes:
- If your git configuration supports pushes to multiple branches, and not only to the current branch, your push may be blocked due to additional and unintended refs being pushed. For more information, see the
push.default
options in the Git documentation. - If secret scanning upon a push times out, GitHub will still scan your commits for secrets after the push.
If the blocked secret was introduced by the latest commit on your branch, you can follow the guidance below.
- Remove the secret from your code.
- Commit the changes, by using
git commit --amend
. - Push your changes with
git push
.
You can also remove the secret if the secret appears in an earlier commit in the Git history.
- Use
git log
to determine which commit surfaced in the push error came first in history. - Start an interactive rebase with
git rebase -i <commit-id>~1
.is the id of the commit from step 1. - Identify your commit to edit by changing
pick
toedit
on the first line of the text that appears in the editor. - Remove the secret from your code.
- Commit the change with
git commit --amend
. - Run
git rebase --continue
to finish the rebase.
Resolving a blocked commit in the web UI
When you use the web UI to attempt to commit a supported secret to a repository or organization with secret scanning as a push protection enabled, GitHub will block the commit.
You will see a dialog box with information about the secret's location, as well as options allowing you to push the secret. The secret will also be underlined in the file so you can easily find it.
To resolve a blocked commit in the web UI, you need to remove the secret from the file, or use the options displayed in the dialog box to allow the secret. For more information about bypassing push protection from the web UI, see "Protecting pushes with secret scanning."
If you confirm a secret is real, you need to remove the secret from the file. Once you remove the secret, you will be able to commit your changes.
