Protecting Passwords

You can follow different password protection approaches depending on your environment setup.
If you specify passwords in plain text, you risk exposing the password to other users. The password might also become exposed in backup files. Do not provide plain-text passwords on production systems.
Follow one of the following approaches for protecting passwords.
  • If you use a ESXCLI host management command interactively and do not specify a user name and password, you are prompted for them. The screen does not echo the password that you enter.
  • For non-interactive use, you can create a session file by using the
    save_session
     option. See the
    vSphere SDK for Perl Programming Guide
    .
  • Target a
    vCenter Server
     system and authenticate to vCenter Single Sign-On. You can save the corresponding session and use it for subsequent connections. See Authenticating Through vCenter Server and vCenter Single Sign-On.
  • Use variables or configuration files.
  • If you are running ESXCLI on a Windows system, you can use the
    --passthroughauth
     option. If the user who runs the command with that option is a known Active Directory user, no password is required.
With ESXCLI, you can run scripts against multiple target servers from the same administration server. You must have the correct privileges to perform the actions on each target, and you must authenticate to the target.
Administrators can place
ESXi
 hosts in lockdown mode for enhanced security. By default, even the root user cannot run ESXCLI commands directly against
ESXi
 hosts in lockdown mode. See ESXCLI and Lockdown Mode and the
vSphere Security
 documentation.
