Starting with VMware Cloud Director, you can change the length of the automatically generated passwords for VMs with enabled guest OS customization.

By default, when activating the guest customization on a VM and using the password auto generation option, VMware Cloud Director generates a password that contains 8 characters.

If you change the length parameter for auto generated password, VMware Cloud Director uses the same configuration for every consecutive VM with enabled guest customization.
