Okta Fastpass requires configuration of Authenticators However no configuration option

Reviewing all of the documentation for Okta FastPass, all of them point to configuring Authenticators (Security>Authenticators). However, there is only Authentication under Security. Is this available in the developer.okta.com?

I am unable to find where the following are…

Authenticator (not located under security)
Trust Devices
Okta FastPass

I am attempting to configure Passwordless sign-on.
