I have deployed a k8s cluster to aws using kops.

The process created a ~./kube/config file with the following structure:

apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: 
      <data_here>
  name: <cluster_name>
contexts:
- context:
    cluster: <cluster_name>
    user: <cluster_name>
  name: <cluster_name>l
current-context: <cluster_name>
kind: Config
preferences: {}
users:
- name: <cluster_name>
  user:
    as-user-extra: {}
    client-certificate-data:
    <client_certificate_data>
    client-key-data: 
    <client-key-data>
    password: <some-password>
    username: admin
- name:<cluster-name>-basic-auth
  user:
    as-user-extra: {}
    password: <some-password>
    username: admin

When (after creating the dashboard) I perform kube proxy and try to access it via localhost, I am prompted with the following screen:

1: Why when I point the file browser to the above created ~./kube/config file I get

Authentication failed

2: When I provide the password included in the ~./kube/config file, I do log in but not as an administrator (e.g. I am unable to view compute resources on the pods)
