# Security Key User Guide
> TruU’s Agentless feature enables access to TruU secured resources without using TruU software (i.e., TruU Mobile App or TruU Platform Authenticator). Instead, you can enroll your security key(s) and use it to login to different resources. See below for prerequisites and steps on how to create and use TruU Agentless feature.
