Abstract
Examples include a CPU coupled to a controller, the CPU to receive a user credential usable by the login executable code to perform device login authentication, determine a first hash value based on the login executable code, determine a second hash value based on the user credential, obtain a third hash value and a fourth hash value from the controller, wherein the third hash value is a reference hash value for the login executable code, and wherein the fourth hash value is a reference hash value for the user credential, compare the first hash value to the third hash value, compare the second hash value to the fourth hash value, execute an OS login service using the login executable code responsive to the first hash value matching the third hash value and the second hash value matching the fourth hash value.
