The service provides two-factor authentication by combining a cloud-based one-time password (OTP) validation service with a USB plug-in, the Yubikey, that sends a time-variant, secure login code. Requests are processed through five frequently synchronized data centers with global coverage, so responses are not dependent on location.
API methods support submission of an application's previously registered Yubikey code and return a one-time password for use in authenticating the user.
The following is a list of libraries from ProgrammableWeb's Library Directory that matched your search term. Although there many different interpretations of the word "library" among software developers, ProgrammableWeb adheres to a specific definition so as to clearly distinguish libraries from SDKs and frameworks in a way that will facilitate clean search results. In ProgrammableWeb's parlance, the term "library" is strictly used to describe a platform-specific software tool that, when installed, results in the provisioning a specific API. Conversely, SDKs are exclusively for consuming APIs and Frameworks are agnostic to specific APIs. If you think a library, SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
