Your vCLI installation includes a credential store. You can establish trust for a user with the credential store.

You can manage the credential store with the credstore-admin utility application, which is located in the /Perl/apps/general directory inside the VMware vSphere CLI directory.

Important

Updating the credential store is a two-step process. First you add the user and password for the server, and then you add the thumbprint for the server.

Procedure
1

Add the user and password for the target ESXi host to the local credential store. 

credstore_admin.pl add --server <esxi_HOSTNAME_OR_IP> --username <user> --password <pwd>
2

Add the thumbprint for the target ESXi host. This thumbprint was returned in the error when you attempted to connect to the host. 

credstore_admin.pl add --server <esxi_HOSTNAME_OR_IP> --thumbprint <thumbprint>
3

If you are using a non-default credential store file, you must pass it in with the --credstore option.

If you do not use the --credstore option, the host becomes accessible without authentication.
