2. Go to the WSSecurity tab, fill the password field, choose if you need the nonce to be base64 encoded or not.
3. Click "Turn WS-Security ON". Now, for every request in scope, a valid security token will be created.

   #WS-SecurityPasswordDigest will be replaced by the Password Digest
   #WS-SecurityNonce will be replaced by the Nonce
   #WS-SecurityCreated will be replaced by the correct time
   #WS-SecurityUUID will be replaced by a random UUID
5. This extension will log in the Extender UI every request after change if you need to debug.
