Git includes a libsecret credential helper (git-credential-libsecret) under /usr/share/doc/git/contrib/credential/libsecret (Debian/Ubuntu) that can be used to interface Git with the libsecret keyring.
This repository contains a simple script git-credential-libsecret-add-https that can be used to add passwords to the libsecret keyring using the git-credential-libsecret credential helper.
NOTE: You don't need this if you use Git Credential Manager.
git-credential-libsecretshould be in$PATHzenity(for the gtk form)seahorse(optional)
Use git config --global credential.helper $(which git-credential-libsecret) to configure the libsecrets credential helper globally or git config --credential.helper $(which git-credential-libsecret) to configure it locally for the project you're in.
Run ./git-credential-libsecret-add-https and fill out the form like this to add a github PAT:
| Host (e.g GitHub.com) | github.com |
|---|---|
| Username | mygithubuser |
| Password | myPAT!2232_ |
Click on OK afterwards. On success, the GNOME keyring GUI (seahorse) will be opened where you can inspect the added key.
That's it, now git push operations should read credentials from the libsecrets keyring instead of displaying a CLI prompt.
Eventually, this script will be rendered obselete if seahorse or a different libsecrets frontend provides built-in functionality to add custom authentication keys.
