Consul cluster auto join - vsphere Password exposed [Vsphere/Vmware]

We have a Consul cluster in VMware.

**Issue:-** when I do ps -ef | grep consul, I am able to see the actual password. How to overcome this issue.

**Consul Version :- 1.2.2**

**PS Output:-**
root 11136 1 0 Feb24 ? 00:00:00 /bin/sh -c /opt/consul/bin/consul agent -config-dir /opt/consul/config/ -retry-join "provider=vsphere category_name=consul-server tag_name=consul-server-sandbox host=example.com user=temp-consul-svc-acct@vsphere.local password=**Password Exposed here** insecure_ssl=true" 2>&1 >> /opt/consul/logs/consul.log
