For CI 3.1.6: Seeking very simple login system, no DB, good example code

If you intend to manage the login credentials manually, you could just setup an array of them in the config file.

like in config.php

PHP Code:

$config['insecure_logins'] = array("username1"=>"password","username2"=>"password",...) 


Then make your login page (form with username and password) post it to a controller and check the config login array to see if it matches.

Of course, you should secure the passwords with something and you should have a brute force detection.

I'd take the time to get one of the authentication systems and use them so you learn how to setup a legitimate authentication system so the next time you actually need something robust, you'll already know one and know how to do it.
