Yubico on Tuesday announced the general availability of YubiKey 5Ci, which the company has advertised as the world’s first security key to incorporate both USB-C and Lightning connectors.

YubiKey 5Ci costs $70 and it can be used by both consumers and enterprises for their iOS, macOS, Windows and Android devices.

In the case of iOS, YubiKey 5Ci works with the LastPass, 1Password, Dashlane, Bitwarden, Idaptive and Okta apps, along with some services through the privacy-oriented browser Brave, including Bitbucket, Login.gov, GitHub and Twitter.

Developers of iOS applications can use the Yubico Mobile SDK for iOS if they want to add support for the YubiKey 5Ci to their app. Dropbox, Keeper Security, SecMaker and others are expected to add support in the upcoming period.

The USB-C connector makes YubiKey 5Ci compatible with nearly every computer or smartphone that has a USB-C port.

YubiKey 5Ci supports multiple authentication protocols and it features FIDO2 and WebAuthn, FIDO U2F, one-time password (OTP), Personal Identity Verification (PIV), and OpenPGP.

“The YubiKey 5Ci fills a critical gap in the mobile authentication ecosystem,” said Jerrod Chong, Chief Solutions Officer at Yubico. “It is the first iOS-friendly security key on the market to offer strong, yet simple authentication over a Lightning connection, while still delivering a unified experience across other mobile, desktop or laptop devices. In an increasingly mobile-first world, where users are not tied to one machine, the YubiKey 5Ci serves an important role as a portable root of trust, proving that users are who they say they are, no matter what device they are on.”

Yubico recently informed customers that it had started replacing YubiKey FIPS (Federal Information Processing Standards) security keys following the discovery of a potentially serious cryptography-related issue that can cause RSA keys and ECDSA signatures generated on these devices to have reduced strength.
