be able to assign a "name" to the listing in the authenticator app.

after scanning my barcode with the authenticator app, there is no header or title or name or whatever you want to call it, so that i can tell one OTP code in my list from another.

ok, i managed to figure it out. you need to add the ISSUER to the URL call.

public function getUrl($user, $hostname, $secret, $issuer) {

    $url =  sprintf("otpauth://totp/%s@%s?secret=%s", $user, $hostname, $secret, $label);
    $encoder = "https://chart.googleapis.com/chart?chs=200x200&chld=M|0&cht=qr&chl=";
    $encoderURL = $encoder . urlencode( sprintf( "otpauth://totp/%s@%s?secret=%s&issuer=%s", $user, $hostname, $secret, $issuer) );

    return $encoderURL;

}

and be sure to adjust the page where you display the QR code

$issuer = urlencode("Some Name Here");
$g = new GoogleAuthenticator();
$link = $g->getUrl($user->getUsername(),$_SERVER['HTTP_HOST'],$secret,$issuer);
