I am pleased to announce that the latest episode of The Polyglot Developer Podcast is now available on pretty much every popular podcast network. This episode, which is episode 25 of the show, is all about two-factor authentication (2FA) and the things you should be familiar with when it comes to implementing it in your web applications.
In this episode titled, Securing Applications with a Second Factor of Authentication, I’m joined by Luke Walker who is a Solutions Architect at Yubico. In case you’re unfamiliar, Yubico creates the very popular YubiKey which is often featured on technology news outlets as being an incredible hardware token for protecting users from malicious circumstances.
When it comes to 2FA, there are many approaches. These approaches can consist of SMS, push notifications, time-based one-time passwords, U2F, or even the new FIDO2. If you’re interested in learning about each, this episode of the podcast should give you some insight before you try to implement them.Read More
As you know, based on a few of the tutorials that I’ve published recently, I have a YubiKey that I’ve been learning how to take full advantage of. In previous tutorials I demonstrated how to implement U2F in your web application, but most YubiKey devices do so much more than just U2F authentication. For example, the YubiKey NEO and YubiKey 5 have support for U2F, FIDO2, OpenPGP, OTP, and a bunch of other crazy technologies.
In this tutorial, we’re going to explore using the YubiKey as a smart card for storing our PGP signing, encryption, and authentication subkeys.Read More
