Editor's Notes

April 01, 2019:

It can be quite a task to keep all of your information safe online. Maybe once it was OK to use the same, or a similar, password to access all of your accounts, but no more. Trying to remember dozens of different passwords is difficult for anyone though. That's where these U2F keys come in handy. They will unlock all of your different accounts and are not susceptible to remote hacking or phishing attacks. If you want the highest level of security, your best options are the UControl Qkey, the Kensington VeriMark, and the CryptoTrust OnlyKey, since they all add an additional layer of protection, such as a biometric thumbprint or PIN code. The HyperFido K18 is without a doubt the most budget-friendly option, and its titanium build makes it nearly indestructible. We liked the compact YubiKey 5C Nano because it supports a variety of protocols and plugs into the newer USB Type-C standard ports, while the Thetis BLE, Yubico Y-256, and Feitian ePass are nice because they can be used on mobile devices.

A wandering writer who spends as much time on the road as in front of a laptop screen, Brett can either be found hacking away furiously at the keyboard or, perhaps, enjoying a whiskey and coke on some exotic beach, sometimes both simultaneously, usually with a four-legged companion by his side. He has been a professional chef, a dog trainer, and a travel correspondent for a well-known Southeast Asian guidebook. He also holds a business degree and has spent more time than he cares to admit in boring office jobs. He has an odd obsession for playing with the latest gadgets and working on motorcycles and old Jeeps. His expertise, honed over years of experience, is in the areas of computers, electronics, travel gear, pet products, and kitchen, office and automotive equipment.
