+## Accessing freenode Via Tor
+
+freenode is also reachable via [Tor<i class="fa fa-external-link" aria-hidden="true"></i>](https://www.torproject.org/), bound to some restrictions. You can't directly connect to chat.freenode.net via Tor
+but rather have to use the following hidden service as server address:
+
+ freenodeok2gncmy.onion
+
+The hidden service requires SASL authentication. In addition, due to
+the abuse that led Tor access to be disabled in the past, we have
+unfortunately had to add another couple of restrictions:
+
+- You must log in using SASL's `EXTERNAL` or `ECDSA-NIST256P-CHALLENGE` (more
+ below)
+- If you log out while connected via Tor, you will not be able to log in without
+ reconnecting.
+
+If you haven't set up the requisite SASL authentication, we recommend SASL
+EXTERNAL. You'll need to generate a client certificate and add that to your
+NickServ account. This is documented [in our knowledge base](kb/using/nickcerts).
+Note that due to the SSL certificates not matching the hidden service,
+you might have to disable the verification in your client.
+
+You'll then want to tell your client to try the `EXTERNAL` mechanism. We lack
+comprehensive documentation for this, but it's a feature in most modern
+clients, so please check their docs for instructions for now.
