Gluu Casa by Gluu is a self-service web portal for end-users to manage authentication and authorization preferences for their account in a Gluu Server. It allows users to enroll, delete, and manage two-factor authentication (2FA) credentials such as FIDO security keys, mobile apps, and phone numbers. Users can turn 2FA on and off, and view and manage authorized external apps and trusted devices. Casa is a plugin-oriented, Java web application that supports the extension of existing functionality and the introduction of new functionality and APIs through plugins. It is tightly integrated with the Gluu Server identity and access management (IAM) platform, using interception scripts for user authentication and the oxd OAuth 2.0 client software for leveraging the Gluu Server for authentication. Casa is available under the Apache License 2.0.
