 Hi @TobiasBg

 The {{{null}}} comes from
 https://core.trac.wordpress.org/browser/trunk/src/wp-includes/user.php#L95
 from inside the {{{function wp_signon}}}.
 The line 95
 {{{#!php
 $user = wp_authenticate( $credentials['user_login'],
 $credentials['user_password'] );
 }}}
 where both  {{{$credentials['user_login'],
 &$credentials['user_password']}}} are {{{NULL}}} when a user access the
 wp-login.php page for first time.

 The {{{wp_signon function}}} is called in
 https://core.trac.wordpress.org/browser/trunk/src/wp-login.php#L1231 with
 an empty array as $credentials argument.
 Line 1231 is:
 {{{$user = wp_signon( array(), $secure_cookie );}}}
