To clone a GitHub repository using an OAuth access token, you can use the following command:

git clone https://github.com/username/repo.git

Replace username with your GitHub username and repo with the name of the repository you want to clone.

To use an OAuth access token, you can add it to the URL using the following syntax:

https://username:<token>@github.com/username/repo.git

Replace username with your GitHub username and <token> with your OAuth access token.

For example, if your GitHub username is davidneman your OAuth access token is abc123, you would use the following command to clone a repository:

git clone https://johnsmith:abc123@github.com/johnsmith/repo.git

When you run this command, Git will prompt you for your GitHub username and password. Enter your GitHub username and use the OAuth access token as your password.

This method of authentication is only recommended if you are unable to use SSH keys for authentication. If you are able to use SSH keys, it is a more secure method of authentication and does not require you to enter your credentials every time you interact with the repository.

How to authenticate to GitHub using personal access token?

You can authenticate to GitHub using a personal access token by following these steps:

1. Generate a personal access token on GitHub by going to your account settings, selecting "Developer settings", then "Personal access tokens", and clicking the "Generate new token" button.

2. Select the scopes or permissions you want to grant to the token. For example, you may want to grant it read-only access to your public repositories or full access to your private repositories.

3. Once you have generated the token, copy it to your clipboard.

4. In your terminal, use the following command to clone a repository:

git clone https://github.com/username/repo.git

5. Replace username with your GitHub username and repo with the name of the repository you want to clone.

6. When prompted for your username and password, enter your GitHub username and use the personal access token as the password.

Alternatively, you can use the personal access token in the URL instead of using your password:

git clone https://token@github.com/username/repo.git

7. Replace token with your personal access token, username with your GitHub username, and repo with the name of the repository you want to clone.

Note:  that personal access tokens are a form of credentials and should be kept secret. Do not share your personal access token with others or include it in public repositories.
