```

Generate a code with a custom length:

```
use Elephant\Otp\OtpCode;

$code = new OtpCode()->generate(12);
```

Choose an alphabet:

```
use Elephant\Otp\Alphabet;
use Elephant\Otp\OtpCode;

$otp = new OtpCode();

$numeric = $otp->generate(alphabet: Alphabet::Numeric);      // 483920
$hex = $otp->generate(16, Alphabet::Hex);                    // 9f03a8c12b4e70df
$readable = $otp->generate(10, Alphabet::Readable);          // 7h4qz9x2wa
