In the Users and Groups tab, you can set the passwords for your initial VMware Cloud Foundation components.
By default, use of DSA fingerprints as a more secure method to validate a host's authenticity is optional and disabled. Unique fingerprints are automatically generated on each host during installation. You can view the fingerprints using the DCUI under View Support Information. Due to the complexity of fingerprints, it is easier to access the hosts using SSH where they can be copied and pasted into the cloud builder deployment parameter sheet. Change the Validate ESXi Thumbprints option to Yes to enable fingerprint validation.
