After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Google2FA for Laravel

Latest Stable Version

Google Two-Factor Authentication for PHP Package for Laravel

Google2FA is a PHP implementation of the Google Two-Factor Authentication Module, supporting the HMAC-Based One-time Password (HOTP) algorithm specified in RFC 4226 and the Time-based One-time Password (TOTP) algorithm specified in RFC 6238.

This package is a Laravel bridge to Google2FA's PHP package.

The intent of this package is to create QRCodes for Google2FA and check user typed codes. If you need to create backup/recovery codes, please check below.

Recovery/Backup codes

if you need to create recovery or backup codes to provide a way for your users to recover a lost account, you can use the Recovery Package.

Demos, Example & Playground

4.2 <= 1.0.1

5.2-5.5 >= 2.0.0 >= 0.1.4

Before Google2FA 2.0 (Laravel 5.1) you have to install pragmarx/google2fa:~1.0, because this package was both a Laravel package and a PHP (agnostic).

Installing

If you prefer inline QRCodes instead of a Google generated url, you'll need to install BaconQrCode:

composer require bacon/bacon-qr-code

One Time Password Lifetime

Usually an OTP lasts forever, until the user logs off your app, but, to improve application safety, you may want to re-ask, only for the Google OTP, from time to time. So you can set a number of minutes here:
