Abstract: An example computing device includes a communication device, an input device, a storage device, firmware stored in the storage device, and a processor. The processor is to: in response to receiving a set of credentials, transmit a request to a server via the communication device, where the request includes the set of credentials and identification information of the computing device; receive a temporary password and expiration information of the temporary password from the server via the communication device; replace a password of the firmware with the temporary password; in response to receiving the temporary password via the input device, determine if the temporary password is valid based on the expiration information; and in response to a determination that the temporary password is valid, provide access to the firmware.

Abstract: An example non-transitory computer-readable storage medium comprising instructions that when executed cause a processor of a computing device to: in response to receiving a chunk size request from a recovery agent executable at an operating system of the computing device, determine a chunk size via firmware instructions of the computing device; transmit the chunk size from the firmware instructions to the recovery agent; receive data chunks of a recovery image from the recovery agent in sequence; store the data chunks in a storage device of the computing device; and construct the recovery image using the data chunks.

Abstract: An example computing device for determining a service trust status can include a processing resource and a memory resource storing instructions thereon, the instructions executable by the processing resource to: receive, at a service, a token and a current value of a counter from a firmware, generate, at the service, an encrypted message utilizing the token and the current value of the counter, provide the encrypted message to an application associated with the service, determine, at the firmware, an authenticity of the encrypted message provided to the application, and send, from the firmware, a trust status of the service to the application.
