Device login authentications
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.
1 . An electronic device, comprising:
a memory storing login executable code;
a controller; and
a central processing unit (CPU) coupled to the 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; and
execute an operating system (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.
2 . The electronic device of claim 1 , wherein the user credential includes one of a password or a user name.
3 . The electronic device of claim 1 , wherein the user credential includes a user name and a password.
4 . The electronic device of claim 1 , wherein the login executable code is a portion of executable code associated with an OS login service of the electronic device.
5 . The electronic device of claim 1 , wherein the OS login service validates the user credential to facilitate access to an OS of the electronic device.
6 . The electronic device of claim 1 , wherein the CPU is further to receive, from a user input communicatively coupled to the CPU, the user credential.
7 . The electronic device of claim 1 , wherein the controller is at least one of an embedded controller or an endpoint security controller.
8 . The electronic device of claim 1 , wherein the CPU is further to determine the first hash value and the second hash value, based on determining that the user credential is not a new user credential.
9 . The electronic device of claim 1 , wherein the CPU is further to obtain the third hash value and the fourth hash value from the controller, based on determining that the user credential is not a new user credential.
