Using Git with GitHub (Passwordless Authentication)

Since GitHub no longer supports password authentication for Git, here's how to connect using SSH keys:

1. Generate SSH Key Pair

Open your terminal and run the following command, replacing `` with your actual email address:

This will prompt you for a passphrase (optional) and save the key pair to your local machine (usually `~/.ssh/`).

2. Add Public Key to GitHub

* Go to your GitHub account settings.
* Navigate to the "SSH and GPG keys" section.
* Click "New SSH key" and provide a title for your key.
* Copy the contents of the file `~/.ssh/id_rsa.pub` (public key) and paste it into the key field on GitHub.
* Click "Add SSH key".

3. Verify Connection

In your terminal, run the following command to test the connection:

If successful, you should see a welcome message from GitHub.

4. Cloning a Repository

Now you can use the `git clone` command followed by the SSH URL of the repository to clone it locally. You'll find the SSH URL on the repository homepage on GitHub. The URL will look something like `git@github.com:/.git`.

Example:

Subsequent Pushes

Once you've made changes and added/committed them, you can push them to your remote repository on GitHub using:
