Yubico YubiKey 5 Series
The best security keys
The Yubico YubiKey 5 Series has versions to fit every modern device and the best documentation to ease in newcomers.
The Yubico YubiKey 5 Series supports a wide array of security protocols, which makes it compatible with more online accounts than most other keys. Yubico also provides the best documentation, and its excellent introductory experience eases the process for newcomers. Compared with other security keys, the 5 Series offers more connection options, including USB-A, USB-C, and a dual-headed USB-C and Lightning-port model for iOS users. All of the full-size keys have a hole so you can attach them to any keychain, making them portable, and in our tests they proved durable after weeks of regular use. The YubiKey 5 Series can be a little more expensive than other keys with similar features, but its robust compatibility with more devices and accounts makes it worth the price.
Yubico Security Key
A great option if you don’t need USB-C or Lightning
Yubico’s less expensive Security Key Series offers the same improvement in account security and excellent documentation. But it’s available only for USB-A ports or NFC devices, and it doesn’t support protocols that some accounts may require, such as OpenPGP, smart card, and OTP.
If USB-A and NFC compatibility are all you need, or if you simply want to test out a key before committing to a more expensive version, get the Yubico Security Key or Yubico Security Key NFC. These keys offer most of the same benefits as the YubiKey 5 Series does—including the ability to secure online accounts with popular services like Google, GitHub, and Dropbox—at a fraction of the price, and they’re just as durable and portable. They also have the same excellent onboarding experience and documentation as the YubiKey 5 Series.
