PHP Package for Yubico authentication

v1.0.0 2018-07-26 19:16 UTC


A modern PHP library for verifying Yubico One-Time Passwords.


This library can be found on Packagist. The recommended way to install this is through composer.

composer require bulldog/yubico


We include Guzzle by default, but you are welcome to use any other PHP HTTP client. You will need to create a new adapter for any other PHP HTTP client and have it implement the OtpAdapterInterface.

include 'vendor/autoload.php';

use Bulldog\Yubico\Yubico;
use Bulldog\Yubico\Adapters\GuzzleAdapter;

$yubico = new Yubico('1234', 'c2VjcmV0X2tleQ==', new GuzzleAdapter());

if($yubico->verify('longonetimepasswordgeneratedfromayubicokey')) {
    echo "That OTP is good!\n";
} else {
    echo "OTP is bad!\n";
    echo $yubico->getReason() . "\n";
