I started getting the same error messages for every service after my last upgrade. I made them go away by creating an alias for credential-manager. git config –global alias.credential-manager “credential-manager-core” Other than the error messages, the credential-manager seems to have been working correctly both before and after creating the alias.
In powershell5 type: Install-Module CredentialManager -force Then New-StoredCredential -Target $url -Username $ENV:Username -Pass …. and later Get-StoredCredential -Target …. Source code for the module is https://github.com/davotronic5000/PowerShell_Credential_Manager == EDIT 2023 == Original is archived, install newer fork with: Install-Module -Name TUN.CredentialManager Check out Github repository for more details.
if $ git config credential.helper returns manager, the password is stored in the windows credential manager, if it returns store, password is stored in a .git-credentials file in the user folder.
