Abstract: An example computing device includes a memory to store a cryptographic key, a processor coupled to the memory, and a set of instructions stored in the memory. The set of instructions, when executed by the processor, is to capture an encrypted passcode originating from a basic input/output system (BIOS) of a managed device as a challenge to grant local access to the BIOS and authenticate with a server using a user credential. When authentication with the server is successful, the set of instructions is to decrypt the encrypted passcode with the cryptographic key to obtain a decrypted passcode and output the decrypted passcode. When authentication with the server is unsuccessful, the set of instructions is to delete the cryptographic key.
