With head-mounted displays (HMDs), users can access and interact with a broad range of applications and data. Although some of this information is privacy-sensitive or even confidential, no intuitive, unobtrusive and secure authentication technique is available yet for HMDs. We present LookUnlock, an authentication technique for HMDs that uses passwords that are composed of spatial and virtual targets. Through a proof-of-concept implementation and security evaluation, we demonstrate that this technique can be efficiently used by people and is resistant to shoulder-surfing attacks.
