[snip] however, several website also propose an additional security to avoid hacking/brute force, they display a 4 digit image with a "random" string including number and letters... something like A3P23. if user do not respect case and string, password is not changed. I would like to know how such system works and if a tutorial exist about that ? [/snip] Google captchaNot that long ago, your reply would have been considered gibberish Satyam
