About push protection from the command line

Push protection prevents you from accidentally committing secrets to a repository by blocking pushes containing supported secrets.

When you attempt to push a supported secret from the command line to a repository secured by push protection, GitHub will block the push.

You should either:

• Remove the secret from your branch. For more information, see "Resolving a blocked push."
• Follow a provided URL to allow the push. For more information, see "Bypassing push protection."

Up to five detected secrets will be displayed at a time on the command line. If a particular secret has already been detected in the repository and an alert already exists, GitHub will not block that secret.

If you confirm a secret is real and that you intend to fix it later, you should aim to remediate the secret as soon as possible. For example, you might revoke the secret and remove the secret from the repository's commit history. Real secrets that have been exposed must be revoked to avoid unauthorized access. You might consider first rotating the secret before revoking it. For more information, see "Removing sensitive data from a repository."

Resolving a blocked push

To resolve a blocked push, you must remove the secret from all of the commits it appears in.

• If the secret was introduced by your latest commit, see "Removing a secret introduced by the latest commit on your branch."
• If the secret appears in earlier commits, see "Removing a secret introduced by an earlier commit on your branch."

Removing a secret introduced by the latest commit on your branch

If the blocked secret was introduced by the latest commit on your branch, you can follow the guidance below.

1. Remove the secret from your code.
2. To commit the changes, run git commit --amend --all. This updates the original commit that introduced the secret instead of creating a new commit.
3. Push your changes with git push.

Removing a secret introduced by an earlier commit on your branch

You can also remove the secret if the secret appears in an earlier commit in the Git history. To do so, you will need to identify which commit first introduced the secret and modify the commit history with an interactive rebase.

1. Examine the error message that displayed when you tried to push your branch, which lists all of the commits that contain the secret.

   remote:   —— GitHub Personal Access Token ——————————————————————
   remote:    locations:
   remote:      - commit: 8728dbe67
   remote:        path: README.md:4
   remote:      - commit: 03d69e5d3
   remote:        path: README.md:4
   remote:      - commit: 8053f7b27
   remote:        path: README.md:4
   

2. Next, run git log to see a full history of all the commits on your branch, along with their corresponding timestamps.

   test-repo (test-branch)]$ git log
   commit 8053f7b27 (HEAD -> main)
   Author: Octocat <1000+octocat@users.noreply.github.com
   Date:   Tue Jan 30 13:03:37 2024 +0100
   
     my fourth commit message
   
   commit 03d69e5d3
   Author: Octocat <1000+octocat@users.noreply.github.com>
   Date:   Tue Jan 30 13:02:59 2024 +0100
   
     my third commit message
   
   commit 8728dbe67
   Author: Octocat <1000+octocat@users.noreply.github.com
   Date:   Tue Jan 30 13:01:36 2024 +0100
   
     my second commit message
   
   commit 6057cbe51
   Author: Octocat <1000+octocat@users.noreply.github.com
   Date:   Tue Jan 30 12:58:24 2024 +0100
   
     my first commit message
   
   

3. Focusing only on the commits that contain the secret, use the output of git log to identify which commit comes earliest in your Git history.

   • In the example, commit 8728dbe67 was the first commit to contain the secret.

4. Start an interactive rebase with git rebase -i <COMMIT-ID>~1.

   • For <COMMIT-ID>, use the commit identified in step 3. For example, git rebase -i 8728dbe67~1.

5. In the editor, choose to edit the commit identified in step 3 by changing pick to edit on the first line of the text.

   edit 8728dbe67 my second commit message
   pick 03d69e5d3 my third commit message
   pick 8053f7b27 my fourth commit message
   

6. Save and close the editor to start the interactive rebase.

7. Remove the secret from your code.

8. Add your changes to the staging area using git add ..

   Note

   The full command is git add .:

   • There is a space between add and ..
   • The period following the space is part of the command.

9. Commit your changes using git commit --amend.

10. Run git rebase --continue to finish the rebase.

11. Push your changes with git push.

Bypassing push protection

If GitHub blocks a secret that you believe is safe to push, you can bypass the block by specifying a reason for allowing the secret to be pushed.

When you allow a secret to be pushed, an alert is created in the Security tab. GitHub closes the alert and doesn't send a notification if you specify that the secret is a false positive or used only in tests. If you specify that the secret is real and that you will fix it later, GitHub keeps the security alert open and sends notifications to the author of the commit, as well as to repository administrators. For more information, see "Managing alerts from secret scanning."

When a contributor bypasses a push protection block for a secret, GitHub also sends an email alert to the organization owners, security managers, and repository administrators who have opted in for email notifications.

If you don't see the option to bypass the block, the repository administrator or organization owner has configured tighter controls around push protection. Instead, you should remove the secret from the commit, or submit a request for "bypass privileges" in order to push the blocked secret. For more information, see "Requesting bypass privileges" in the GitHub Enterprise Cloud documentation.

1. Visit the URL returned by GitHub when your push was blocked.

2. Choose the option that best describes why you should be able to push the secret.

   • If the secret is only used in tests and poses no threat, click It's used in tests.
   • If the detected string is not a secret, click It's a false positive.
   • If the secret is real but you intend to fix it later, click I'll fix it later.

3. Click Allow me to push this secret.

4. Reattempt the push on the command line within three hours. If you have not pushed within three hours, you will need to repeat this process.
