So that you don't have to constantly enter your username and password while working with the git repository, you can save this information as follows:
git config credential.helper store
git config user.name "Goran Štimac"
git config user.email "firstname.lastname@example.org"
Of course, instead of my name and email details you will enter your own details.
You can also use this short command if you clone a repository:
git clone https://<USERNAME>:<PASSWORD>@github.com/path/to/repo.git
IMPORTANT these commands save the login information to a file located in the repository directory:
as plain text which means you can easily reveal user data to others so use it wisely!
