just wondered what you think of sqlite3 as an alternative to MySQl ; i find it easier for development but recognize it might be less secure, i'm using it anyway live on a web using f3 login here:
http://ghanahomefood.com/login . I have sql injection covered (i think)
Had a quick look at controller code and see your using brcypt. I'm using that as well but also using a salt like this:
$crypt = \Bcrypt::instance();
$salt = $f3->get('salt');
$this->cryptTheirName = $crypt->hash($this->theirName,$salt) ;
$this->cryptTheirPassword = $crypt->hash($this->theirPassword,$salt);
