1. A method for managing an authentication credential of an identity of a machine of a computer system via a remote network connection with the machine, the method comprising: accessing in the computer system, at least one credential parameter for an authentication process for the identity of the machine, the at least one credential parameter being included in an authentication file associated with the computer system; determining a password complexity rule for the identity based at least on the at least one accessed credential parameter, thereby enabling automatic generation of a password consistent with the determined password complexity rule for a user associated with the identity of the machine; determining a credential management protocol, based on interaction with the machine via the remote network connection; and performing a security control operation for the identity based at least on the credential management protocol, the security control operation including at least one of: enabling updating a password associated with the identity at the machine based on the automatically generated password; enforcing a password change operation for the identity at the machine; determining whether the password associated with the identity complies with a security policy; or determining whether the determined password complexity rule complies with the security policy.
