Issue Description

Same issue that we had with Azure CLI a few weeks back. ARM template deployment task needs to change the parameter "--password" with "certificate". Looks like ARM template deployment task utilizes AZ CLI for auth. That's where the issue is. Please read below the log.

We need this fixed ASAP! This is breaking all production pipelines.
