I know how to do 1 password protection really hard to crack.
Wat it does is the first time u open the hack it safes a 30 words and numbers key (random) on ur computer, then it checks if a "urkey".txt file exists in ur server (free subdomain or w/e), if yes it allows u to run the hack.
And if u try to open the hack with out the key check it give u an error.
Im Not sharing the code, if u want it, PM.
