. Use your host's database management tool —usually it's phpMyAdmin— to list the contents of your site's jos_admintools_storage table (where jos_ is your site's prefix). Find the only record in the table (the key value is "cparams") and take a peek at the contents of the value column. It contains a long text. At some point you will see something like "masterpassword":"mypassword". The mypassword part is your master password.
