thats really a stupid question...that noone can answer?
for example...
what kind of database are you using to store passwords...or are you using file access...do you want to include a username...of just one password....how long can the password be?
you are i assume a newbie...asking questions like this will get you nothing but flame...read something about it...dont ask for someone to code something unless you want to pay them to do so.
doss
