title: Google Cloud Paltform: Personal credentials in GCP
body: <p>I was working with service accounts and got this at one point when I was trying out logging in with a person account, but I'm not sure what it means in terms of what exactly is being stored or what the ramifications mean. What credentials are stored on the VM and where are they stored? Suppose I want to go back and remove those credentials, how would I do this?</p>
  
  <pre><code>You are running on a Google Compute Engine virtual machine.
  It is recommended that you use service accounts for authentication.
  
  You can run:
  
    $ gcloud config set account ``ACCOUNT''
  
  to switch accounts if necessary.
  
  Your credentials may be visible to others with access to this
  virtual machine. Are you sure you want to authenticate with
  your personal account?
