YubiKey 5Ci

The YubiKey 5Ci is a dual-connector lightning and USB-C multi-protocol security key equipped with FIDO2/WebAuthn, FIDO U2F, OTP (one-time password), PIV (Smart Card), and OpenPGP. With support for multiple authentication protocols, the YubiKey 5Ci delivers strong multi-factor, second-factor (2FA), and single-factor passwordless authentication for a simple and seamless user experience across the entire computing ecosystem.

For all our iOS users out there, we know that you’re eager to get started with the YubiKey 5Ci. Thanks to our strong ecosystem of partners, we are proud to launch the YubiKey 5Ci with native iOS app support from 1Password, Bitwarden, Dashlane, Idaptive, Keeper Security, LastPass, and Okta. Monkton Rebar and XTN also support the YubiKey 5Ci in their latest software development kits.

You can also access some of your favorite services with the YubiKey 5Ci through the Brave iOS browser, which is the first and only iOS browser to support WebAuthn over the Lightning connector at this time. These services include: Bitbucket.org, GitHub.com, Login.gov, Twitter.com, and 1Password.com.

Yubico continues to collaborate with services and applications on their support of the YubiKey 5Ci, with the goal of our users’ favorite, day-to-day apps being added soon. Partners with anticipated YubiKey 5Ci app support include: Dropbox, Keeper Security, SecMaker, and more.
