Reads cached credentials using the configured Git credential helper.
^{(MIT license)}

go install github.com/VonC/git-cred@latest 

A git credential helper is used to cache HTTPS remote Git hosting service credentials (username/password or token)

You can used that helper to query credentials manually:

credhelper=$(git config credential.helper) printf "host=github.com\nprotocol=https" | git-credential-${credhelper} get

This works for any Mac/Linux/Windows cached credentials.

And if you want to set a new password/token, it is even more cumbersome:

credhelper=$(git config credential.helper) printf "host=github.com\nprotocol=https\nusername=VonC\npassword=xxx" | git-credential-${credhelper} set

• Replace the complex command line by a tool able to quickly read/set/erase cached credentials, no matter your credential helper.
• Cross-platform.

• git-cred will read your current credential helper
• By default, in a repository, it will display cached credentials for the current folder/repository

Since the executable follows the naming convention git-xxx (here git-cred or git-cred.exe), that means you can also type:
git cred.
As if "cred" was a git command. It works if the executable git-cred(.exe) is in your $PATH/%PATH%.

get is the default command for git-cred.
You do not need to add get.

git cred -u VonC -s github.com # or (same) git cred -u VonC -s github.com get

cd /path/to/local/github.com/cloned/repository git cred # or (same) git cred get

git cred -u VonC -s github.com set <password or token>

cd /path/to/local/github.com/cloned/repository git cred -u VonC set <password or token>

git cred -u VonC -s github.com erase

cd /path/to/local/github.com/cloned/repository git cred -u VonC erase
