Whether to enable Howdy and its PAM module for face recognition. See services.linux-enable-ir-emitter for enabling the IR emitter support.
Howdy is not a safe alternative to unlocking with your password. It can be fooled using a well-printed photo. Do not use it as the sole authentication method for your system.
By default, the config.services.howdy.control option is set to
"required", meaning it will act as a second-factor authentication in most services. To change this, set the option to "sufficient".
