Answer 1

As far as I know, there are simply two safe ways: ssh or passwd encrypted using a keystore.

SSH

1. Log in your github;
2. Visit: https://github.com/settings/keys;
3. New SSH key;
4. cat ~/.ssh/id_rsa.pub, paste it there, name and save it (if you have no such file, generate one for yourself by ssh-keygen -t rsa - just Enter for all prompts);
5. Go to your local repository and update your remote by git remote set-url origin git+ssh://git@github.com/username/reponame.git - you can check it first by git remote -v);
6. Here you go, just touch t; git add t; git commit -m "test"; git push and confirm yes to enjoy the password-free world.

passwd ENCRYPTED using a keystore

If you just use git config --global credential.helper store as others mentioned, your unencrypted passwords will be just stored in a plain text under ~/.git-credentials which is not safe as it sounds.

Try to encrypt it as

sudo apt-get install libgnome-keyring-dev
sudo make --directory=/usr/share/doc/git/contrib/credential/gnome-keyring
git config --global credential.helper /usr/share/doc/git/contrib/credential/gnome-keyring/git-credential-gnome-keyring

git config --global credential.helper store

In this case, you are using https://git@github.com/username/reponame.git.
