If you are adding a Generic SSH system, you can add a user name and password or a SSH key for an account to be used to access the system using a secure shell session. See Adding SSH keys for information on adding SSH keys to Privileged Access Service.
You cannot use Privileged Access Service to manage account passwords for generic SSH systems. However, you can use Privileged Access Service to store the account information securely, then use the account to open secure shell sessions on target systems without knowing the password.
You can specify any valid local user account and password. In most cases, however, you would specify root or an account with similar privileges for which you want to manage the password.
