U2F security keys are being lauded as the best option available for universal second step authentication, and the models on our list represent the greatest the industry has to offer currently.

Editor's Notes

December 22, 2020:

As the ports and ways we connect with our devices change, it is important that our security keys also evolve to reflect that. With this in mind, we updated our selections to include more models with Type-C connectors, such as the Yubico YubiKey 5Ci, which also has a lightening connector; the Solo Tap; and the Thetis Fido, which actually has a Type-A on it but comes with an adapter. Also, because more people are keeping sensitive information on phones, we wanted to add options that feature either NFC pairing or Bluetooth, like the Yubico YubiKey 5 NFC, Thetis BLE, and the previously mentioned Solo Tap.

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.
