Access Manager has been launched to enhance the PubNub Data Stream Network by providing serverless access control, enabling developers to manage detailed permissions for real-time applications and data. It allows developers to grant Publish/Subscribe permissions at varying levels, such as person, device, channel, or key, and integrates with existing authentication systems like Facebook Connect, Twitter, Google, LDAP, or custom solutions. This feature is ideal for creating subscription services for real-time financial, traffic, or social data streams, point-to-point applications like home automation, and social apps where secure peer-to-peer communication is required. Access Manager includes a working demo and comprehensive resources such as a Getting Started Guide and Security Overview, and it can be accessed through the Developer’s Portal.
