# Authentik
Authentik is an open-source Identity Provider (IDP) that aims to unify your identity needs into a single platform. It can replace Okta, Active Directory, and Auth0, offering a comprehensive solution for managing user identities. Built with the public benefit in mind, Authentik Security Inc. has developed this product on top of the open-source project.

## Features
- **Self-host anywhere**: Authentik allows you to self-host your identity provider, giving you complete control over your data and infrastructure.
- **Multi-Factor Authentication (MFA)**: This feature helps ensure the security of your user accounts by requiring multiple forms of identification before granting access.
- **Conditional Access**: Authentik enables you to set conditions for accessing specific resources based on factors such as location, device, or time.
- **Open-source and source available**: The project is fully open-source, with its source code available for anyone to inspect and contribute to.
- **Application Proxy**: This feature allows you to securely connect your applications to Authentik without the need to modify them.
- **Enterprise support**: Authentik offers dedicated enterprise-level support to ensure smooth deployment and operation of the product within your organization.

### Supported Protocols
- **SAML 2.0**
- **OAuth 2.0 and OIDC**
