GIT & GITHUB AUTHENTICATION SETUP

This guide explains two ways to authenticate with GitHub:

  1. SSH (recommended for long-term use)
  2. HTTPS

OPTION 1: SSH

SSH uses a key pair and avoids password prompts.

Using Git Bash

Git Bash often handles SSH keys automatically. If cloning works without asking for a password, you do not need to start the SSH agent or add the key manually (STEP 2).

STEP 1: Generate an SSH Key

ssh-keygen -t ed25519 -C "your_email@example.com"

Press Enter to accept defaults.

STEP 2: Start SSH Agent and Add Key

eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_ed25519

STEP 3: Add Public Key to GitHub

cat ~/.ssh/id_ed25519.pub
  • Copy the output
  • GitHub → Settings → SSH and GPG keys
  • New SSH key → Paste → Save

STEP 4: Clone Using SSH

git clone git@github.com:USERNAME/REPOSITORY.git

DONE.

OPTION 2: HTTPS

HTTPS uses your GitHub username and a Personal Access Token.

STEP 1: Create a GitHub Token

  • Go to GitHub → Settings
  • Developer settings → Personal access tokens
  • Create a Fine-grained token
  • Give access to repositories
  • Copy the token (you will not see it again)

STEP 2: Clone the Repository

git clone https://github.com/USERNAME/REPOSITORY.git

STEP 3: Authenticate When prompted:

  • Username: your GitHub username
  • Password: paste the token

DONE.
