I have tried different browsers on the Mac, the only browsers that work are Chrome and Edge. With FIDO2 based passwordless authentication, the ‘FIDO2 Security Key’ option within the Azure AD (e.g., under Security) has to be enabled first.Īgain, the user goes through self-registration ( ) prior to the Yubikey becoming available. The OTP method does not impose special requirements on the browsers, which means it works on any browsers, as well as on the APM Edge client, which leverages certain browser functions Note ‘Touch your Yubikey’, which is needed before an OTP is generated. Yubico argues that it is more secure as unlike a soft authenticator, the secrets are not saved within the authenticator itself, but rather in a secure element within the Yubikey. The Yubico Authenticator works with the Yubikey to generate the OTP. The user must also add an authenticator app via self-registration ( ), be sure to click on the highlighted, this allows you to enrol the ‘Yubico Authenticator’ ( ). This process is documented by Microsoft ( ). If Yubikey is used for OTP, Azure AD needs to have MFA enabled, a ‘Conditional Access’ policy is created to ‘Require multi-factor authentication’ for your selected apps. Since authentication is offloaded to Azure AD, both the OTP and FIDO2 passwordless authentication methods are now available. My choice of integration is via OIDC, but SAML is an equally valid option. My particular use case is to leverage an IDaaS (e.g., Azure AD) as an IDP and use the APM as the SP. There are a number of articles on DevCentral that cover programming the APM to receive the Yubikey OTP and then send it over to Yubico’s validation servers via a side band connection for OTP verification. YubiKey can also present itself as a PIV smartcard that contains a client certificate. ), browser support for U2F and WebAuthn are shown below. – no username is enteredįIDO2 is an evolution of U2F and is dependent upon WebAuthn (client API implemented within the browser) and CTAP2 (authenticator API that enables FIDO2-capable devices to interface to external/roaming authenticators over Bluetooth, USB or Near field communication (NFC)).

Once the Yubikey is registered with an application (e.g., Azure Portal) for FIDO2 authentication, the user touches the Yubikey, optionally provides a PIN code for the key, logs straight in.

FIDO2įIDO2 enables passwordless authentication. In the case of Gmail, once the user’s credentials are verified, the user touches the Yubikey for 2 nd factor.

Once the registration is complete, the user can then use the authenticator as the 2 nd factor. This method requires the user to register the authenticator (e.g., Yubikey) with the application (e.g., Gmail) first, during which a key pair is generated by the authenticator, and the public key is sent and stored on the application. FIDO U2FįIDO U2F or U2F for short, mitigates MITM. In the case of Okta, the secrets can be uploaded directly into Okta and validation happens within Okta. When a service receives an OTP, it reaches out to Yubico for validation.

Yubikey OTP integrates with a large number of services (e.g., Gmail, LastPass). However, the new secret has to be uploaded to Yubico’s validation servers ( ) otherwise OTP will stop working. Yubico provides a tool that allows you to re-program the key, giving it a different secret. E.g., A fake site impersonating a legitimate site can trick the user into entering the OTP and subsequently forwards it to the real site.Īll Yubikey’s by default have manufacture assigned secrets registered with Yubico’s own validation servers. However, it is also the weakest, as it does not mitigate against MITM attacks.

OTP is probably the simplest, with a one-time password being used, typically as the 2 nd factor. As far as authentication goes, it supports a list of the following mechanisms.Įach of the above-mentioned protocols has its own set of requirements and is therefore not universally supported everywhere. The Yubikey ( ) supports three major functions, authentication, signing and encryption.
