Most of the time people keep asking how to keep flood ids safe as we know many flood apps contain keyloggers or mail protocols and the developers manage to retrieve ur passwords or sometime even using simple crackers people can dupe u of ur passwords, so the simplest method is to make sure that even if anyone manages to hа*ċk ur flood series, u should have adopted some policy to retrieve the series back.
All u need to do is to put a phone number in any random id of flood series (avoid putting in 1st ids) like if i have a flood series nimwar-1- to nimwar-200- then i will use my phone number in any random jid which is difficult to guess like nimwar-127- so if my flood series gets hacked and the hacker changes the password of the series, i can use the forgot password on nimbuzz client and i will get the new password of nimwar-127- as an sms on my phone and i can change the password of the whole series and get my series back. Dont use email as that wont be of any help because using forgot password link of email will allow u to reset the password of the single jid while the sms will fetch u the existing password set by the hacker, hence u will be able to hа*ċk ur series back.
