Problem

Why is Git always asking for my password? How to setup GitHub to SSH access.

Solution

Setup your github account using the Terminal and SSH.

Step by step

  1. How to Install Git on Ubuntu 22.04 and 24.04 
    sudo apt update
sudo apt install git
git --version
  2. Tell to git who you are. 
    git config --global user.name "rogelioprieto"
git config --global user.email "myname@googlemail.com"
git config --list
cat ~/.gitconfig
  3. Generate a new SSH key 
    ls -al ~/.ssh
ssh-keygen -t ed25519 -C "myname@googlemail.com"
eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_ed25519
gh ssh-key add ~/.ssh/id_ed25519.pub
  4. Copy the new SSH key into clipboard 
    #copy the ssh key into clipboard
sudo apt-get install xclip
xclip -selection clipboard < ~/.ssh/id_ed25519.pub
  5. Paste the new SSH key to your GitHub account: https://docs.github.com/en/authentication/connecting-to-github-with-ssh/adding-a-new-ssh-key-to-your-github-account
  6. Connect to and clone the repository 
    #Test ssh connection
ssh -T git@github.com
#make dir and clone
mkdir ~/github
cd ~/github/
git clone git@github.com:rogelioprieto/linux-tips.git
git status
ls -la
cd linux-tips
git status
  7. Finally, you can edit or create a file and push into the repository 
    git add .
git status
git commit -m "added minor changes"
git push -u origin master
git status

or you can use these commands in one line:

git add . && git commit -m "added minor changes" && git push -u origin master
