# Why TLS?
You may have noticed that Kanidm requires you to configure TLS in
your container - or that you provide something *with* TLS in front like haproxy.
your container - or that you provide something *with* TLS in front, like haproxy.
This is due to a single setting on the server - `secure_cookies`
## What are Secure Cookies?
`secure-cookies` is a flag set in cookies that "asks" a client to transmit them
back to the origin site if and only if https is present in the URL.

CA verification is *not* checked - you can use invalid, out of date certificates,
or even certificates where the `subjectAltName` does not match, but the client
must see https:// as the destination else it *will not* send the cookies.

## How does that affect Kanidm?
## How Does That Affect Kanidm?
Kanidm's authentication system is a stepped challenge response design, where you
initially request an "intent" to authenticate. Once you establish this intent,
the server sets up a session-id into a cookie, and informs the client of
what authentication methods can proceed.
When you then go to continue the authentication, if you do NOT have a https url,
the cookie with the session-id is not transmitted. The server detects this as
an invalid-state request in the authentication design and immediately disconnects
you from attempting to continue the authentication as you may be using an insecure
channel.
If you do NOT have a HTTPS URL, the cookie with the session-id is not transmitted.
The server detects this as an invalid-state request in the authentication design,
and immediately breaks the connection, because it appears insecure.
Simply put, we are trying to use settings like secure_cookies to add constraints
to the server so that you *must* perform and adhere to best practices - such
