Config file should be mode 0600.

[GoogleCodeExporter]

When launching the lpws binary should check the permissions of the config file 
and abort with a big fat warning if the config file's permission mode is not 
0600 (read/write owner only). The file will contain a cleartext password 
allowing it to read any other users password.
