Introduction

The Rublon .Net SDK library is a client-side implementation of the Rublon authentication service written in C# (.Net Framework). It forms a convenient C# coding language facade for the service's REST interface.

Use cases

Rublon provides an additional secury layer:

1. during logging in to your system, adding a second (or additional) authentication factor,
2. while conducting a security-sensitive transactions, providing a user the means for identity confirmation before changing passwords or conducting a money transfer.

To be able to perform an additional authentication using Rublon, the user must first be authenticated in a different way, e.g. with a username and password (usually we call it first factor). It is a necessary step, because upon Rublon's initialization the service must receive certain information about the user:

• a unique Id, stored in the system (inafter called the integrated system) implementing the Rublon service,
• the user's email address.

To experience the full measure of two-factor authentication, the end-user should install the Rublon mobile app, available on all leading smartphone systems. However, having those with older phone devices in mind or those who do not want to install any additional apps on their phones, we prepared a Email2FA process which does not require using an additional device of any kind.

Principles of operation

User protection

User protection is active when a user's email address in the integrated system can be matched to a user in the Rublon service. For this purpose, the user's email is sent to Rublon servers.
