    What Is Mobile Authentication? Mobile Authentication.png

    Today, mobile phones can pretty much do anything that was once traditionally done on a computer. Online shopping, paying bills, checking bank accounts, you name it. Both consumers and employers tend to use personal mobile devices in the office and on the go, so securing those devices from potential hackers is a crucial step to implement in your routine.

    Mobile authentication is the verification of a user’s identity through the use of a mobile device and one or more authentication methods to ensure secure access. If you want to keep your online accounts safe, enabling mobile authentication across your devices is the single most important step you can take. While no security measure is fully hack proof, there are steps to lock access to your important accounts and information.

    Create a Cold War-Era Numbers Station with Twilio Voice and Python Flask Create a Cold War-Era Numbers Station with Twilio Voice and Python Flask

    Put on your fedora and dark glasses, because you’re about to become a Cold War-era numbers station operator!

    What is a numbers station, I hear you ask? A numbers station is a radio station in the shortwave frequency band that periodically reads out a sequence of numbers, popularly believed to be a secret code for intelligence officers listening for encrypted information. Numbers stations appeared during World War I and are likely to have become much more prevalent during the Cold War.

    In the past, the numbers were often spoken in what sounded like a creepy voice, probably due to the poor radio transmission quality available at the time. You can listen to a few recent examples of numbers station transmissions on the Crypto Museum's website. Some numbers stations survive to this very day.

    Since many people enjoy cracking secret codes, I thought it would be fun to show you …

    Authenticate Uploads to Amazon S3 in SlimPHP Using Twilio Verify Authenticate Uploads to S3 in SlimPHP Using Twilio Verify

    It's hard to get away from cloud storage in modern web application development; and with good reason!

    Infrastructure as a Service (IaaS) providers such as Amazon Web Services, Microsoft Azure, Google Cloud Platform, and Alibaba Cloud make storing data anywhere in the world almost trivial, regardless of programming language, operating system, and budget.

    Whether you're storing instrumentation data from a Raspberry Pi-based weather station, or medical records for a nation-state, cloud providers are up to the task. However, they don't do everything for you. They won’t handle tasks such as only letting valid users store legitimate files.

    So in this tutorial, you're going to learn how to use Twilio's Verify API to validate uploads to an Amazon S3 bucket in a Slim framework application which uses the Twig templating engine for the view templates.

    How to Integrate Ngrok in a Twilio Java Application header - How to Integrate Ngrok in a Twilio Java Application

    When you are developing an application that uses Twilio services you need to expose your webhooks on public URLs that can be reached by Twilio. If you have followed some of the tutorials that we published on this blog you know that we recommend using the excellent ngrok tool to generate temporary public URLs for your development web server. Ngrok is an incredibly useful tool that creates a tunnel from a URL on the ngrok.io domain to your application running on your computer. You can then configure your webhook using the ngrok URL and when Twilio sends a request to it, ngrok redirects it to your application.

    If you use ngrok frequently enough, it pays off to become a paid customer, which allows you to secure a permanent URL.

    In this article I’m going to show you how to fully automate ngrok by incorporating it into your Java application. …
