how to push using package repository

[svattenky]

My config is as such

    release: {
            options: {
                bump: true, //default: true
                // changelog: false, //default: false
                // changelogText: '<%= version %>\n', //default: '### <%= version %> - <%= grunt.template.today("yyyy-mm-dd") %>\n'
                file: 'package.json', //default: package.json
                add: true, //default: true
                commit: true, //default: true
                tag: true, //default: true
                push: true, //default: true
                pushTags: false, //default: true
                npm: true, //default: true
                npmtag: false, //default: no tag
                indentation: '\t', //default: '  ' (two spa
                tagName: 'v<%= version %>', //default: '<%= version %>'
                commitMessage: 'chore(package.json): Release v<%= version %>', //default: 'release <%= version %>'
                beforeBump: [],
                remote: 'origin' // optional grunt tasks to run after file versions are bumped
}

and I want to be able to push to my internal repository using the credentials of the user doing the grunt command so that it is a commit made by them rather than using some standard user. Grunt bump does it this way. Is there a way to achieve this with this package
