Username/Password Authenticator Plugin Example

The Curity Identity Server has a built-in HTML Form Authenticator.
This example plugin provides a similar implementation using the Curity SDK.

Customization

The Branding and User Experience Resources provide example customizations.
In more advanced scenarios you may also want to take closer control over runtime behavior.
For these cases, you can use this repo as a starting point and adapt it as required.

Prerequisites

Before using this plugin you must be running version 9.2 or later of the Curity Identity Server.
Also ensure that you are using credential_mode=standard for your credential manager.
