Abstract

Systems and methods provide a password reset for a management controller, which is not exposed to the Internet. Upon receiving a request to reset the password, the management controller generates computer-readable information such as a barcode, where the computer-readable information indicates attributes of an information handling system associated with the management controller as well as a timestamp. A user can transmit the computer-readable information to a vendor application service via for example a mobile device that reads the computer-readable information. The vendor application service verifies the request and generates a temporary password from the timestamp and the attributes. Independently of the vendor application service, the management controller also generates the temporary password from the timestamp in the attributes. The vendor application service may then cause the temporary password to be sent to verified contact information.

Claims19

Dependent claims

A chassis comprising:

a plurality of Information Handling Systems (IHSs), each comprising one or more hardware CPUs (Central Processing Units);
a management controller implemented in a first IHS of the plurality of IHSs, wherein the management controller includes a hardware processor and a memory, wherein the hardware processor of the management controller is configured to read and execute computer-readable instructions from the memory to cause the hardware processor of the management controller to support remote monitoring and administration of the first IHS, further wherein the hardware processor of the management controller is configured to:
receive a request to reset a first password, wherein the first password provides access to the management controller;
generate and display machine-readable information based upon a plurality of attributes of the first IHS;
generate a temporary password based upon the plurality of attributes of the first IHS and a timestamp associated with the request, including inputting the timestamp and the plurality of attributes into a hashing algorithm and receiving the temporary password as output of the hashing algorithm;
receive input comprising a text string in a user interface (UI);
verify that the text string matches the temporary password;
and
provide access to further functions of the management controller in response to the text string matching the temporary password.
