How to Get a Better Two-Factor Authentication Cardinal for $20

Two years after debuting his first open up-source two-factor-authentication (2FA) USB security key at the 2017 Shmoocon hacker briefing, former graduate student and present-day entrepreneur Conor Patrick showed off his latest cosmos, the Solo security central, at this past weekend's Shmoocon in Washington, D.C.

Like its predecessor, the Solo key is inexpensive to buy at $20, and yous can build i yourself instead if you choose — all the hardware instructions and software are posted online.

The new Solo key supports the new FIDO2 standard equally well as the older U2F standard, comes in a USB-C variant also as in the traditional USB-A format and has a soft plastic trounce to cover the electronics. (The original key, the U2F Zero, had an exposed excursion board.)

There's also a Solo key with unlocked software and then that hackers tin can tinker with it. A version with NFC wireless support, the Solo Tap, is on the manner and will interact with Android phones.

Patrick has likewise set up a company to manufacture and sell the Solo keys, and you tin buy one directly from the company website as well equally Amazon.

Security keys are used as a second factor in ii-gene authentication protocols, and are even more secure than temporary codes sent via SMS text message.

For case, you tin can set upwards security keys in Google, and when y'all log into Google from a new computer for the first time, y'all can plug the security fundamental into the computer's USB port to verify who you lot are. (You'll all the same have to enter a password start, but the FIDO2 standard means you might not accept to soon.)

Either USB-A or the USB-C versions of the Solo Fundamental should work with whatever online service that supports U2F or FIDO2, including Google, Facebook, Dropbox and the Dashlane and Keeper password managers.

All the same, the Solo key won't work with LastPass, as that password manager supports only Yubico's proprietary Yubikey security keys. Nor is it likely that the upcoming Solo Tap will work with iOS, which does not support NFC to the same degree as Android.

(iOS devices already work with the Bluetooth-based Titan security keyfobs sold past Feitian and Google, and a Yubikey out afterward this twelvemonth will have a Lightning plug to piece of work with iPhones and iPads.)

The USB-A version of the Solo key costs $20, and at the moment it has pretty much the aforementioned capabilities equally Yubico's identically priced, basic blue Security Key (which not a Yubikey, as information technology uses just open standards).

But Patrick said the Solo key will go firmware updates to extend its capabilities into other authentication formats such as one-fourth dimension passwords, static passwords and smart cards, which virtually Yubikeys already support.

The USB-C Solo key sells for $25, and there'south no directly competitor to it yet. Yubico's Yubikey 4 series includes USB-C models, but they don't back up FIDO2. The Yubikey 5 series does support FIDO2 and has USB-C variants, but they price at least twice equally much as the USB-C Solo due to Yubico's proprietary software.

We were given a Solo Central to play with at Patrick'due south presentation, and had no trouble adding it as a second security key on a Google business relationship. The only slight hiccup was when Chrome asked permission to examine the fundamental'southward software; afterwards permission was granted, everything went smoothly. Later, we used the Solo key to log into a new laptop, and everything worked without a hitch.
