OATH

For an overview of the OATH features that became available with the 5.7.x firmware, see 5.7 - 5.6 Firmware Specifics.

The OATH application can store up to 64 OATH credentials on firmware 5.7.0 and later (32 on older firmware), either OATH-TOTP (time-based One-Time Password) or OATH-HOTP (counter-based One-Time Password). These credentials are separate from those stored in the OTP application, and can only be accessed through the CCID channel. In order to manage these credentials and read the OTPs generated by the YubiKey, requires the Yubico Authenticator.

To restrict access to the OTPs, set an access code for the OATH application.

Note

Developers: Using the OATH application functions on iOS requires the Yubico iOS SDK.

HOTP and TOTP

Both OATH-TOTP and OATH-HOTP credentials are described in detail in the OATH Overview.
