As the PR is created, it cannot be merged since approval is required. In this case, there is no need to restore anything, since we do not want to leave traces of our branch anyway. Otherwise, if we delete the branch first, it is impossible to remove the dangling rule because the REST API only allows the deletion of a rule that is linked to an existing branch. 3 Jonno_FTW 7 mo.

It is based on the concept of workflows, which automate the execution of code when an event happens. Most likely your password is cached to your user.email and your token isn't being used instead. Launching the CI/CD and R Collectives and community editing features for SSL certificate rejected trying to access GitHub over HTTPS behind firewall, SSH Key - Still asking for password and passphrase, Git authentication fails after enabling 2FA, git clone shows "Initialized empty Git repository in xxxxxxxxx(my directory)".

Each personal access token has one or multiple scopes such as8: An interesting scope is workflow, because it grants the ability to add and update GitHub Actions workflow files (we will detail the concept of workflow right after). It is possible to remove the reviewers and add our branch to the list of authorized deployment branches, perform the secrets extraction and finally restore the reviewers and delete our branch from the authorized list: For the branch protection, it is a bit more complicated. Another interesting kind of service connections is the GitHub one. Or there is on other button/option? The first starter course is a lesson on Git and GitHub. Asking for help, clarification, or responding to other answers. From the GitHub documentation7: Fine-grained personal access tokens have several security advantages over personal access tokens (classic): Personal access tokens are less restrictive and depending on the permissions of the user which creates the token, they can be used to access a lot of resources. remote: Write access to repository not granted. It is used to connect to GitHub to push, pull or interact with the GitHub API. You can find the URL of the local repository by opening the command line and typing git remote -v: Turns out for whatever reason you have to use ssh and cannot use PAT and https.

You can disable or configure GitHub Actions for a specific repository. Check the Software Requirements page. A snake biting its own tail. Creating these protection rules that require one approval on a pull request by another organization member significantly reduces the risk of compromising an account, as the code needs to be manually reviewed by another user. Since the base branch is considered trusted, workflows triggered by these events will always run, regardless of approval settings. Indeed, by default, branch protection prevents any branch deletion: But now, the protection applies to our branch: For this reason, to bypass this protection, we need to first push an empty file and check if a protection is applying to our branch. Go to your local repository folder and find a hidden folder called ".git". To use these secrets in a pipeline, a user must actually be able to modify an existing one that already has access to the targeted secrets, or they must be able to create a new one and give it the correct permissions. For example, it is possible to ask it to include the repo, context (environment) and ref (branch) claims: Once this kind of OIDC trust relationship is configured, if an attacker knows its existence and can deploy a workflow under the required conditions, they could also generate access tokens that can be used to interact with Azure services through the different APIs. In my case, I've used fine granted PAT, with all permissions, but somehow it doesn't work. The below link shows all three methods.

Thanks for contributing an answer to Stack Overflow! You should ensure that the SSH key you are using is attached to your personal account on GitHub.

Click the Pull or Deploy tab. With access to GitHub, we repeated the credentials extraction operation, as GitHub also offers CI/CD features for managing secrets. Then, the file path can be referenced in the pipeline as $(secretFile.secureFilePath). For instance, the Azure Resource Manager type allows the pipeline to log in to an Azure tenant as a service principal. Suspicious referee report, are "suggested citations" from a paper mill? Therefore, a full review of all tokens and user permissions should be performed to only give access to resources that are needed by applying the principle of least privilege.
