What problem does this address?#
I want a simple way to push/pull code from GitHub without having to enter my password or username.
Setup#
The installation instructions are adapted from those in the git credential manager repository.
Download git-credential-manager#
Download the latest .deb package, and run the following:
sudo dpkg -i <path-to-package>
git-credential-manager configure
Select credential store#
There were a few options for how to store credentials. I went with the GPG/pass approach. To select this store:
git config --global credential.credentialStore gpg
We then need to install the required packages. GPG is installed by default in most distributions, pass was not installed on mine so run:
sudo apt install pass
Next generate the GPG key pair with:
gpg --gen-key
Following the prompts will give an output of the form:
❯ gpg --gen-key

GnuPG needs to construct a user ID to identify your key.
Real name: fake name
Email address: fake_name@email.com
You selected this USER-ID:
"fake name <fake_name@email.com>"
Change (N)ame, (E)mail, or (O)kay/(Q)uit? o

pub rsa3072 2023-10-03 [SC] [expires: 2025-10-02]
<gpg-id>
uid fake name <fake_name@email.com>
sub rsa3072 2023-10-03 [E] [expires: 2025-10-02]
where <gpg-id> is a big hexadecimal number of the form 1B61835F2E64E1C62A9A472. We need this <gpg-id> to initalize the store with:
pass init <gpg-id>
Now next time we run git push, it should prompt a sign-in with Github.
