Password Manager cannot be installed using Managed Service Accounts (gMSA's). The option to choose a gMSA is not available during installation.
Post installation the service account and the application pool identity accounts can be changed to a gMSA if required, but an ordinary account with the appropriate privileges will be needed to logon to the administration site. A gMSA cannot be used as a Domain Management account. This will have to be an ordinary account with the appropriate permissions granted.
