Abstract
A method for unlocking a firmware setup utility of a computer server without a firmware setup utility user password. The method includes booting the server to a firmware setup utility interface and receiving a user request to unlock the firmware setup utility without the password. The method further includes receiving, via a web interface to a baseboard management controller (BMC) of the server, login credentials for accessing a BMC configuration, wherein the login credentials are authenticated by the BMC. The firmware setup utility causes, in response to the request, the BMC to send a nonce code to a registered destination address stored by the BMC. User input containing the nonce code is received through the web interface to the BMC, and the firmware setup utility is unlocked in response to determining that the nonce code received through the BMC web interface matches the nonce code in the message.
