Comment (by vhomenko):

 A snippet to reduce the noise level of the errors, in case of entering a
 wrong email address into the login form.

 {{{
 add_filter( 'wp_login_errors', 'consolidate_wrong_user_id_errors', 20 );

 function consolidate_wrong_user_id_errors( $errors ) {
         if ( ! is_wp_error( $errors ) ) return $errors;
         if ( 2 !== count( $errors->errors ) ) return $errors;

         $codes = $errors->get_error_codes();
         $is_invalid_username = in_array( 'invalid_username', $codes );
         $is_invalid_email = in_array( 'invalid_email', $codes );

         if ( $is_invalid_username && $is_invalid_email ) {
                 $errors->remove( 'invalid_username' );
         }

         return $errors;
 }
 }}}
