It implements TOTP according to [RFC6238](https://tools.ietf.org/html/rfc6238) **Other hash functions other than SHA1 only work for Google-Authenticator at the moment!** Example: -------- [](#example) Look at the function [TestGenerator()](https://github.com/poetter-sebastian/SimpleThenticator/blob/main/tests/SimpleAuthenticatorTest.php) in [tests](https://github.com/poetter-sebastian/SimpleThenticator/tree/main/tests) Or use this [sample script](https://github.com/poetter-sebastian/SimpleThenticator/blob/main/sample/sample.php): ``` require_once('../src/SimpleAuthenticator.php'); use SebastianDevs\SimpleAuthenticator; $auth = new SimpleAuthenticator(6, 'SHA1'); try { $secret = $auth->createSecret(); } catch (Exception $e) { echo $e->getMessage(); exit(); } echo 'Secret is: ' . $secret . '\n'; $qrCodeUrl = $auth->getQRCodeGoogleUrl($secret, 'Testo@test.test', 'Business'); echo 'QR-Code: ' . $qrCodeUrl . '\n'; $oneCode = $auth->getCode($secret); echo 'Checking Code ' . $oneCode . ' and Secret ' . $secret . ':\n'; echo $auth->verifyCode($secret, $oneCode, 2)? 'OK': 'NOT OK'; ``` output: ``` Secret is: S4VWK6CWPA3PMU2HZM2YEDZGSF2DQL3V Google Charts URL for the QR-Code: https://api.qrserver.com/v1/create-qr-code/?data=otpauth%3A%2F%2Ftotp%2FVintage+Story%3ATesto%40test.test%3Fsecret%3DS4VWK6CWPA3PMU2HZM2YEDZGSF2DQL3V%26algorithm%3DSHA256%26issuer%3DVintage+Story&size=200x200&ecc=M Checking Code '439195' and Secret 'S4VWK6CWPA3PMU2HZM2YEDZGSF2DQL3V': OK ``` Installation: ------------- [](#installation) ### [Composer](https://getcomposer.org/doc/01-basic-usage.md) [](#composer) - To use this package perform the following command: `composer require sebastiandevs/simplethenticator` ### Simple usage [](#simple-usage) - To use the class just import the [SimpleAuthenticator.php](https://github.com/poetter-sebastian/SimpleThenticator/blob/main/src/SimpleAuthenticator.php) as `require_once()` in your PHP code Run Tests: ---------- [](#run-tests) - All tests are inside the [tests folder](https://github.com/poetter-sebastian/SimpleThenticator/tree/main/tests). - Execute `composer run-script build-dev` to install all dependencies - Execute `composer run-script test` to run all tests in the test folder Better library: --------------- [](#better-library) - For better code or complex implementations: please use [RobThree/TwoFactorAuth](https://github.com/RobThree/TwoFactorAuth)! ### Health Score 50 — FairBetter than 96% of packages Maintenance82 Actively maintained with recent releases Popularity33 Limited adoption so far Community8 Small or concentrated contributor base Maturity60 Established project with proven stability Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
