Safe access for multiple user on the same account on a linux machine

First task is to create your own token (generate new token):
https://github.com/settings/tokens

you can test it with
curl -u <token>:x-oauth-basic https://api.github.com/user

Then write it down to a specific file in home/user/subuser/.netrc , where you just created your directory
content of the file:

machine github.com
login <githubUserName>
password <token>
protocol https

#Then encrypt it
gpg --gen-key

gpg --encrypt --armor --recipient user.name@yourmail.com .netrc

#then give it the right permission, and the right file extension
chmod 700 ./.netrc.asc
mv ./.netrc.asc ./.netrc.gpg

#Now, try to clone your repo:
git clone https://github.com/githubuser/repo.git

give you token as password
#Inform it of your local configuration, so that next time you don't need to rewrite it:

git config --local credential.helper 'netrc -f /home/user/subuser/.netrc.gpg -d -v'
you might need to do download the perl script (see this gist) and make is executable and inside the current $PATH:
chmod +x ~/bin/credential-git-credential-netrc

Test with
gpg --decrypt /home/user/subuser/.netrc.gpg
cross check git config with
git config -e

git config --local user.name githubUserName
git config --local user.email user.name@yourmail.com
