passwords

问题 I'm new to Codeigniter and trying to make a user registration. And I've met strange thing.

问题 Good Afternoon Guys and Girls, Hopefully this will be a quick and easy question. I am building an App that requires the user to input their login details for an online service that it links to.

问题 I'm running a web service on Django. Users register to my system and provide me login details (username and password) for a 3rd party web service).

问题 Example security code: a35sfj9ksdf How can I ask a user for several characters (e.g. first, forth and ninth) of their security code and then check these?
