 Similarly, WebAuthn and its various other names like Passkeys, FIDO2 or "scan the QR code to log in"
 will [only work over TLS](https://developer.mozilla.org/en-US/docs/Web/API/Web_Authentication_API).
 
+There are a variety of ways that you can configure TLS between your load balancer and Kanidm.
+Ultimately, any option that maintains the confidentiality and integrity of the communication will
+suffice. Some options include, but are not limited to:
+
+- Generating a self-signed certificate
+  - Utilize certificate pinning to ensure that the load balancer only trusts connections made with
+  that particular certificate
+- Not terminating TLS / TLS passthrough / TCP proxy
+- Running your own certificate authority (CA)
+
+The "best" option for you will depend on a number of factors, including your threat model and the
+specifc load balancer you are using.
