Configuration concepts
The articles in this section cover the four OTP application configurations, as well as the NDEF (NFC Data Exchange Format) tag:
- Yubico OTP
- Initiative for Open Authentication HMAC-based OTP (OATH HOTP)
- Static password
- Challenge-response (using the HMAC-SHA1 or Yubico OTP algorithms)
The purpose of these articles is to convey the following information:
- what each configuration is and how it works
- YubiKey nuances related to each configuration
- an overview of the SDK functionality in each area
- intended applications and limitations of each configuration
These articles build on the topics discussed in the OTP application concepts section. You may find it helpful to refer back to that section as you develop an understanding of the configurations.
