My recommendation is to clone Git repositories using HTTPS instead of SSH. To make that git don’t ask for username and password each time you want to communicate with the remote, use GitHub Credential Manager.
This is how to setup it on Ubuntu Linux:
Installation
Install git if you already haven’t. (sudo apt install git).
Download GitHub Credential Manager.
Go to https://github.com/git-ecosystem/git-credential-manager/releases, and here choose latest gcm-linux_amd64 with .deb extension.
Open directory where you downloaded the file in Ubuntu terminal. Then run:
sudo apt install ./<.deb file>
Note: I had an information about some “Permission denied”, but everything worked after all.
Setting up
First run. You don’t have to provide any input.
git credential-manager configure
Then tell git to use credential manager:
git config --global credential.credentialStore secretservice
Finishing
You are all set up! Next time, when you will use a command, that will require authentication, you can log in to GitHub by transfering a request to the browser, and finishing there. You will know what to do.
Then you can forget about authentication. GitHub Credential Manager will do that for you!
