Help with credentials in powershell

Hello,

I am using a script that is helping me change the computer names remotely within our domain through a .csv. I have tested this out on multiple computers and this has worked flawlessly.

The only problem I am having is I have to enter my domain credential for every computer name changed. Is there a way to automate this process within the script?

Below is the script I am currently using.

Thanks in advance for any assistance.
