This is how I installed Git and authenticated with my GitHub repo using a ssh key using Windows OS

Download and install git

• https://git-scm.com/

Create a folder for a git repo

• Create a folder in your windows system
• Open folder in git by right clicking and selecting git bash

Create a ssh key (Open ssh type)

ssh-keygen -t ed25519 -C "AddYourEmail@email.com"

• Follow prompts and save to your .ssh folder
• View and copy your public key you need to add this later

  nano <YOUR_LOCATION_YOU_ADDED_ABOVE>/.ssh/github-key.pub
  

Go to your github security settings

• https://github.com/settings/profile
• Cick SSH and GPG keys
• Click NewSSH key
• Add public key you copied before new SSH key and add add a Title
• Add SSH key
• You should have a success notification

Add your ssh-agent connection to .profile

• Open your git folder using git bash again
• Create a .profile or edit it

  nano ~/.profile
  

• Add these contents. Remember to edit to set path to your ssh key!

  #! /bin/bash 
  eval `ssh-agent -s` 
  ssh-add ~/.ssh/<ADD_PATH_TO_SSH_KEY>
  

Add your ssh-agent connection to .bashrc

• You will need to add to bash as well. eg. I am using git terminal in Android studio so I will need to change bashrc
• Create a .bashrc or edit it

  nano ~/.bashrc
  

• Add these contents. Remember to edit to set path to your ssh key!

  #! /bin/bash 
  eval `ssh-agent -s` 
  ssh-add ~/.ssh/<ADD_PATH_TO_SSH_KEY>
  

• Restart the app that you are using git cli
• You should see something like

  Agent pid XXXX
  Identity added: xxxxxxxxx
  

• Go to one of your repos and fetch remote repo by running

  git fetch
  

• This should fetch contents without asking for key or ssh agent
