Features

• Authentication Frameworks - Provides a comprehensive framework for implementing various authentication strategies and managing user sessions in web applications.
• OAuth and Identity Providers - Integrates with external OAuth and OIDC identity providers to allow users to sign in with third-party accounts.
• Credential Authentication - Verifies user identities via traditional username and password combinations managed directly by the application.
• Authentication Middleware - Implements security middleware to verify identity and enforce access control on incoming requests.
• External Identity Provider Integration - Integrates with external OAuth services, email-based passwordless systems, and directories to authenticate users.
• Identity Store Adapters - Uses a pluggable adapter system to persist user accounts and authentication data into external databases.
• User Profile Management - Provides functionality for storing and managing user account attributes and profiles through pluggable database adapters.
• External Database Persistence - Persists authentication session data and user profiles in external databases to maintain state across server instances.
• Cross-Framework Logic - Ensures uniform identity management and session behavior across various web frameworks and server environments.
• Identity Abstractions - Standardizes diverse authentication methods like OAuth, Email, and Credentials through a unified configuration object.
• OAuth 2.0 Authorization Flows - Implements standard OAuth 2.0 authorization flows, including the exchange of authorization codes for access tokens.
• OAuth Provider Integrations - Facilitates user sign-in by connecting to external identity providers and mapping third-party accounts.
• Session Management Frameworks - Maintains user state using either signed JWT tokens or database-backed sessions across server and client environments.
• Stateless Session Management - Maintains user identity state using signed JWTs stored in encrypted cookies for stateless session operation.
• User Authentication Flows - Supports diverse identity verification methods including OAuth, email magic links, passwords, and passkeys.
• Web Application Security - Provides security middleware to protect web applications using CSRF token validation and restrictive cookie policies.
• Database Adapters - Implements a pluggable adapter system to decouple authentication data from specific database engines and ORMs.
• OAuth Provider Registrations - Allows the registration of any OIDC or OAuth compliant identity provider via custom configuration objects.
• Route Middleware - Provides middleware to intercept requests and verify session validity before granting access to protected routes.
• Authentication Workflows - Implements configurable workflows for sign-in, including support for passwords, magic links, and passkeys.
• Cross-Site Request Forgery Protections - Provides cryptographically secure token validation to prevent cross-site request forgery on state-changing authentication requests.
• Application Request Security - Protects sensitive routes by enforcing CSRF tokens and applying restrictive cookie policies during login.
• Provider Configurations - Provides tools for customizing third-party identity provider settings, including scope adjustments and user profile mapping.
• Third-Party Integrations - Connects to third-party identity services using built-in or custom configurations to handle user authentication.
• Sign-In Page Customizations - Provides the ability to replace default sign-in pages with custom branded interfaces while maintaining backend integration.
