Which password to use?
For users there are three passwords in SixXS:
The SixXS password
This is the main username/password for logging into the website and it can also be used for TIC. This is the combination of username (eg "EXA1-SIXXS") and password provided to you in the approval email.
The TIC password
The is an optional per-tunnel password that can be set in the Tunnel Details page (log in to your user home, select the tunnel from the list).
Instead of specifying just "EXA1-SIXXS" as a username one can use "EXA1-SIXXS/T12345" along with the configured TIC password.
Using a TIC password restricts usage of that TIC session to the given tunnel. This can be handy in situations where a device does not allow for specifying a tunnel_id or to keep the main website password separate from configuration files.
The Heartbeat/AYIYA password
This is a per-tunnel heartbeat/AYIYA password.
This password is negotiated during the TIC transaction.
It is used to authenticate the heartbeat/AYIYA packets and typically is not seen or used directly by users.
