How to check git credentials for remote on a Windows machine with PowerShell?

Question

I'm currently working on a script which syncs several git repositories and updates them locally with git fetch --prune and git pull.

Now I try to automate the first run of the script, where the git credential manager would prompt for the remote credential.

Is there any change way to check / test if there is already set a credential for the remote (origin) with PowerShell?

Note: I already tried to find a workaround with libgit2sharp but got stuck...

Used Approach

• Since git-credential manages uses the WindowsVault on Windows systems I, decided to test the credentials there.
• Therefore I used the PowerShell module CredentialManager to test and store the required credentials:
  • Get-StoredCredential -Target "git:https://<GitLab_FQDN>"
• So with these I can check the credentials for remote host before invoking any git command.

Answer 1

You can use

git config --list --show-origin

In case of credentials you can see something like credetial.helper=wincred.
