Short description

Prefer core auth APIs. If building custom forms, use nonces, strong password handling, and `wp_signon` carefully.

Create user

$user_id = wp_insert_user([
    'user_login' => $login,
    'user_email' => $email,
    'user_pass'  => $password,
    'role'       => 'subscriber',
]);
