OneTimePassword (OTP) for Laravel

A Laravel layer for local OTP authentication.

This is an attempt to make OTP implementation in Laravel easy.

Being a layer, this could not exist without these core dependencies:

• the package robthree/twofactorauth does the real OTP logic, and
• the included merged version of phpqrcode does the real QRCode generation.

Being local, otp-laravel does, by default, not depend on network services to generate QR codes (with thanks to the offline example of RobThree using phpqrcode).

Quickstart setup

Follow the Quickstart to setup a new Laravel project using this OTP package.

The most important part is, in the LoginController, to replace the existing use AuthenticatesUsers to use Dcvn\Otp\Http\Controllers\AuthenticatesUsers;.

If you feel real lazy, copy this quickstart.sh script to the base dir of your projects, and run it (at your own risk).

Features

Assuming using the quickstart way, but you can implement how you like it.

• Adds an otp_secret column to the users table (migration).
• Adds an OTP input to the login page, and validates for it when it has been set up.
• Adds routes, controller methods and views for setting up OTP for a user.
• By default, you are only allowed to do the setup for your own user.
• Many settings are configurable by config and .env.
• Translations available in english and dutch.
• OneTimePassword as alias in the app.

OneTimePassword example

<?php
$otp = OneTimePassword::configured();
if ($otp->verifyCode($user->otp_secret), $request->verification) { /* ... */ }

Publish files

You don't necessarily need this, but you can copy config, language or view files to your project this way:

artisan vendor:publish --provider "Dcvn\Otp\Providers\OtpServiceProvider" --tag config
artisan vendor:publish --provider "Dcvn\Otp\Providers\OtpServiceProvider" --tag lang
artisan vendor:publish --provider "Dcvn\Otp\Providers\OtpServiceProvider" --tag views

To override the access policy (for example to allow (only) admin users to do the setup), copy this to your AuthServiceProvider's boot() method, then modify it:

<?php
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Support\Facades\Gate;

// in boot():
Gate::define('otp.setup', function (Authenticatable $user, Authenticatable $model) {
    return $user->id == $model->id;
});
