Change admin password

Hi,

I have been trying to change the password for the FreePBX Administration area (http://pbx.local/admin) (Username:freepbx/Password:fpbx) for a while now. I cannot seem to find anything relevant to the freepbx/fpbx login for the web config. I am hoping someone will be able to provide me with a solution. If you need any other info, please ask and I will get it for you.

FreePBX 2.7.0.1
AsteriskNOW 1.5.0
