Usage
-----

[](#usage)

Generation of QR code for TOTP compatible applications.

```
$keyGenerator = new KeyGenerator();
$qrCodeGenerator = new QrCodeGenerator();

// Generate keys randomly, save this key in association with the target account.
$keyBytes = $keyGenerator->generateRandom(10);

$qrDataUri = $qrCodeGenerator->getQrCodeDataUri($keyBytes, 'sample@foo.bar', 'Sample');

```

Authentication using pin.

```
// It reads the key of the target account and compares it with the input pin.
$passcodeGenerator = new PasscodeGenerator(new HMacSigner($keyBytes));
$counter = new TotpCounter();
$time = time();

$valid = $passcodeGenerator->verifyTimeoutCode($pin, $counter->getValueAtTime($time));

```
