LinOTP

LinOTP is a linux based solution to manage authentication devices for two factor authentication with One time passwords. It is implemented as a web service based on the python framework Pylons. Thus it requires a webserver to run in.

LinOTP is mainly developed by the German company LSE Leading Security Experts GmbH. It's core components are licensed under the GNU Affero General Public License.

It is the only opensource authentication server certified^[1] by the OATH initiative for open authentication.

As a web service LinOTP provides a REST-like web API. All functions can be accessed via Pylons controllers. Responses are returned as a JSON object.

LinOTP is designed in a modular way enabling user store modules and token modules. Thus it is capable of supporting a wide range of different tokens.

Being written in Python the program itself comes as the source code. The code is available via the Python Package Index PyPI or from the project website linotp.org.

Unfortunately there is no code repository publically available.
