You can connect to xmpp.dk using your favourite Jabber client. There's a long list of clients available over at [xmpp.org][jabber-clients]. 

## To create a @xmpp.dk account
Registration is handled in-band by your Jabber/XMPP client. This is the only way to create an account on xmpp.dk.  
  
Simply add _username_@xmpp.dk in your client and click “register” or check the box to “create this account on the server” to sign up.

## Connection Information

### Server

* Internet: xmpp.dk
* Tor: mjfjbs3547exsy6r.onion
* Tor v3: 3hbedm3irbcgr6yanknkeizk7bjetlw5tlulooz73w2w3dgeptm7zeid.onion

### Security

* Require SSL/TLS
* When connecting to the hidden service you will get a warning about the TLS certificate not matching the host name. This is OK.

## Secure Communication
The connection between your client and xmpp.net is encrypted using TLS. The server requires TLS connections to other XMPP servers.
This means that if you can't connect to a friend, their provider is not configured to use TLS and the xmpp.dk server will refuse the connection. Your friend
should either convince their provider to enable TLS server-to-server connections, or switch to a provider that has proper encrypted transport support. 
Since you can't (and shouldn't) trust your xmpp server, I require you always enable secure end-to-end encryption in your chat client. Supported modes are: 

* [Off-The-Record (OTR)][off-the-record]
* [OMEMO][omemo]
* GPG

This will give you end-to-end encrypted chat that cannot be decrypted while in transit and, depending on the settings of your client, will not be logged on your local machine. 

## Federation
xmpp.dk allows federated connections to all other *S2S TLS-enabled Jabber servers* so you can chat with anyone that has a Jabber account as long as their provider supports TLS and is configured correctly.
