The company's new security key features both USB-C and Lightning connectors on a single device which makes it the ideal solution for enterprises and consumers that require strong hardware-backed authentication on iOS, Android, macOS or Windows devices.

Yubico had told us that GitHub recognized the 5ci on iOS, but we couldn't get GitHub to recognize the key on a USB-C-enabled Windows PC, even though we were using the fearless web browser as Yubico suggested.

Through the Yubico Developer Program, the company is continuing to work with the creators of popular iOS apps and browser supported services.

At this point in time, the YubiKey 5Ci is supported by Okta, 1Password, Bitwarden, Idaptive, Dashlane, and LastPass on iOS, as well as the fearless for iOS browser for logins on,, Twitter, GitHub, and 1Password's website. Dropbox, Keeper Security, SecMaker and others are partners that are planning to add YubiKey 5Ci support to their apps soon.

The USB-C port make the YubiKey 5Ci compatible with almost every USB-C equipped laptop or mobile device (except the iPad Pro with USB-C, which according to Yubico, is not now supported), allowing it to work with hundreds of applications and services listed in the Works with YubiKey catalog today. The key won't yet work on iPad Pros with a USB-C port, however.

"The YubiKey 5Ci fills a critical gap in the mobile authentication ecosystem", Yubico's Jerrod Chong says.

If you've been looking for a way to further improve security when it comes to managing all of your online accounts, and you happen to be an iPhone user, then you need to check out this tiny security key.

The security key, which costs $70, supports a variety of standards for passwordless authentication, including FIDO2, WebAuthn, FIDO U2F, OTP (one-time-password), PIV (Smart Card), and OpenPGP.

We got a YubiKey 5ci in advance and borrowed an iPhone to see how well the two devices play together.
