How to use ssh keys to easily push to / pull from GitHub
You need to:
Configure your remote to use the ssh version of the GitHub repo address instead of the http version.
Generate a public/private ssh key pair, and add the public key to your GitHub account manually via your web browser.
Details
Configure your remote to use the ssh version of the GitHub repo address instead of the http version. Ex:
For this repo of mine: https://github.com/ElectricRCAircraftGuy/eRCaGuy_hello_world, use this ssh URL: git#github.com:ElectricRCAircraftGuy/eRCaGuy_hello_world.git instead of this HTTPS one: https://github.com/ElectricRCAircraftGuy/eRCaGuy_hello_world.git:
# View your current remote servers and their URLs
git remote -v
# Set your `origin` remote server to use the ssh URL instead
# of the HTTPS one
git remote set-url origin https://github.com/ElectricRCAircraftGuy/eRCaGuy_hello_world.git
Generate a public/private ssh key pair, and add the public key to your GitHub account manually via your web browser.
See my full notes on ssh stuff here: https://github.com/ElectricRCAircraftGuy/eRCaGuy_dotfiles/tree/master/home/.ssh
# generate a public/private ssh key pair
ssh-keygen -t ed25519 -C "your_email#example.com"
# Ensure the ssh-agent is running (this starts the `ssh-agent`)
eval "$(ssh-agent -s)"
# Add your private key to it; update the path to your private key below, as
# required, based on what path you interactively selected above when
# generating the key
ssh-add ~/.ssh/id_ed25519
# Verify what keys have been added to the ssh-agent by listing
# (`-l`) currently-added keys.
# A. If you see "Could not open a connection to your authentication agent.",
# it means the `ssh-agent` has not been started yet, so you must start it
# with `eval "$(ssh-agent -s)"`.
# B. If you see "The agent has no identities.", it means the ssh-agent is
# running but you haven't added any ssh keys to it, so run `ssh-add
# path/to/private_key` to add a key to the agent.
ssh-add -l
Now log into github in a web browser and click on your profile image --> Settings --> SSH and GPG keys (on left) --> New SSH key --> copy and paste the contents of your .pub key file (ex: run cat ~/.ssh/id_ed25519.pub on your Ubuntu machine to read the public key--adjust that path as necessary if you used a different file name) into GitHub here --> click "Add SSH key".
Now, whenever you type git push it automatically works, using your ssh key.

You can provide the username once as part of the https git remote address.
First run git remote -vv to get the full, current remote URL.
Then to change your existing remote, you can do a command like:
git remote set-url origin https://yourname#github.com/yourname/yourrepo.git
where the new part is yourname# (substitute your github user name) and the rest of the URL should be the same as shown in git remote -vv
