Cloning a Repository via HTTPS with Fine-Grained Personal Access Token (PAT)

Introduction

Cloning a repository is a fundamental operation in Git and GitHub, and doing it securely is crucial for maintaining the integrity of your codebase. Two primary methods for cloning a GitHub repository are via SSH and HTTPS. This blog post will focus on the HTTPS method, specifically leveraging Fine-Grained Personal Access Tokens (PAT) for authentication.

Why HTTPS with PAT?

When you clone a repository using HTTPS, you authenticate with a token that grants access and permissions, and PATs offer several advantages in this context. Before we delve into the process, let's understand what a PAT is.

Understanding Personal Access Tokens (PATs)

In the realm of Git and GitHub, a Personal Access Token (PAT) is a secure and revocable authentication token tied to a user's GitHub account. Like passwords, PATs provide account-wide security scope, however, they also offer a controlled and secure means of authentication which passwords fail to provide.

Advantages of PATs in Version Control

1. Fine-Grained Control: PATs can be tailored with specific scopes or permissions, enabling granular control over user actions (e.g., read access, write access, repository-specific access).

2. Expiration and Refresh: PATs can be configured to expire after a set period, reducing risks associated with long-lived credentials. Users need to periodically refresh or generate new tokens, aligning with security best practices.

3. Seamless Integration: PATs seamlessly integrate with automation, and CI/CD (Continuous Integration, Continuous Deployment) systems, ensuring consistent and coherent authentication without exposing sensitive credentials.

4. Access Revocation: Revoking access is simplified by invalidating a PAT, providing better control and management of access credentials.

Step-by-Step Guide: Generating PAT and Cloning

1. Generate a PAT:

• Click on your profile image at the top right corner of your GitHub account.

• Select Settings from the dropdown

  

• Navigate to Developer settings on the left sidebar

  

• Click on Personal access tokens and select Fine-grained tokens

  

• Click Generate new token

  

• Fill in token information and set expiration.

  

• Skip the Repository access ,Permissions , and Overview sections for now (for educational purposes). We will revisit them later.

  

  

  

• Click Generate token .

  

• Click the copy icon and save the token securely.

  

2. Clone Using HTTPS with PAT:

• Copy the HTTPS URL for your repository.

  

  

• Go to your terminal, type git clone and paste the repository's URL without pressing Enter

  

• Copy your PAT from where it has been saved.

• Paste the PAT followed by @ before the GitHub URL.

  

git clone https://[PAT]@github.com/[username]/[repo].git

• Add a file (e.g., README.md) to the repo and git push

3. Troubleshooting Access Denied Error:

• If you encounter Permission to the repository is denied error:

  

• Go back to the fine-grained tokens under Personal access tokens

• Click on the subject token, then Edit

  

• Adjust repository and account permissions as needed.

  

  In case your GitHub account is personal rather than a company account utilized by a development team, refer to the steps in the image.

  It suggests selecting all repository permissions and all account permissions to all resources, assuming it's your personal account, and you'll be utilizing all available resources.

  However, for administrators or team leads responsible for granting permissions to other team members, a more nuanced approach is necessary.

  For example, individuals requiring Administration permissions—meaning they can create repositories, delete repositories, change repository settings, etc.—should receive a PAT with those permission masks opened. On the other hand, individuals with lower privileges should be provided a separate PAT with those permissions closed.

  This tailored approach ensures that permissions align with the specific needs and roles within your development team.

• Click Update

  

• Retry git push

• 

By following these steps, you ensure a secure and controlled method of cloning repositories using HTTPS with Fine-Grained PATs, enhancing security and access management.

Take your GitHub security and permissions to the next level with Personal Access Tokens. Give it a try to empower your account with controlled access.
