Increase Identity Safe password limit

I just discovered nis2012 identity safe master password is limited to 20 characters. (I assume the password for the backup file is also limited to 20 characters.) Where do I change config to enable a longer password?

 

i understand nis2013 is in beta. Please raise the (master & backup file) password length limit to 100 in the next version.  I need that many characters to keep my paranoia in check.

 

thanx
