If we add public key in our git account, we can pull/push project easily without password.
However, we need passwd every time when we pull/push project from https format url.
It is too frequently to do such things and it is annoying. So, to avoid entering password
from time to time, we can set credential in our local git project, that would make things go
easily. Here is the solution:
cd project
git config --global credential.helper cache git config --global credential.helper 'cache --timeout=3600'
Good news, we do not have to offer password in 1 hours now.
