    let charset = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!$()";
    let mut password = String::new();
    let charset_len = charset.len();

    let mut rng = rand::thread_rng();
    for _ in 0..password_length {
        let idx = rng.gen_range(0..charset_len);
        password.push(charset.chars().nth(idx).unwrap());
