+### Accessing web apps in a secure browser context
 
 Some web applications require a [secure context](https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts) to function correctly.
 A browser typically considers an origin secure if the connection is to `localhost`, or over `HTTPS`.
 
-As Coder Connect uses its own hostnames and does not provide TLS to the browser, Google Chrome and Firefox will not allow any web APIs that require a secure context.
+Because Coder Connect uses its own hostnames and does not provide TLS to the browser, Google Chrome and Firefox will not allow any web APIs that require a secure context.
+Even though the browser displays a warning about an insecure connection without `HTTPS`, the underlying tunnel is encrypted with WireGuard in the same fashion as other Coder workspace connections (e.g. `coder port-forward`).
