YubiKeys in the 5 Series can hold up to 25 resident keys.įIDO2 support is available to the iPad Pro via the USB-C or Lightning® connectors of the YubiKey 5Ci. As these credentials can accommodate the username and other data, this enables truly passwordless authentication on sites and applications that support the WebAuthn protocol. In addition to providing phishing-resistant two-factor authentication, the FIDO2 application on the YubiKey allows for the storage of resident credentials, also called discoverable credentials. The FIDO2 standard offers the same high level of security as FIDO U2F, since it is based on public key cryptography. Challenge-Response can also be used with software (such as Yubico Authenticator) to act as a single OATH-TOTP credential.Īll three of these OTPs are described in more detail below, under OATH and under OTP. Touch-triggered OTP also supports a static password and Challenge-Response.We support OATH-HOTP and OATH-TOTP directly on the OATH function on the YubiKey (usually called OATH and used with Yubico authenticator).

We support the Yubico OTP and OATH-HOTP directly on the touch-triggered OTP function on the YubiKey.

Note that the OTP and OATH categories overlap technically, there are three true OTPs: The applications are all separate from each other, with separate storage for keys and credentials.įor information on managing all these applications, see Tools and Troubleshooting.
