Methods, systems, and apparatus, including computer programs encoded on a computer-readable storage medium, for pre-boot network-based authentication. In some implementations, a computing device enters a UEFI environment upon powering on the computing device. While in the UEFI environment, the computing device restricts booting of an operating system of the computing device, accesses a signed certificate corresponding to a particular user, sends a verification request to a server system over a communication network, and receives a verification response from the server system over the communication network. In response to receiving the verification response, the computing device (i) enables the operating system to boot and (ii) verifies the identity of the particular user to the operating system such that the operating system logs in the particular user without requiring further proof of identity for the particular user.
