Authgear is an authentication & user management solution that makes it very easy for developers to integrate and customize their consumer applications. It includes these features out of the box:

• Zero trust authentication architecture with OpenID Connect (OIDC) standard.
• Easy-to-use interfaces for user registration and login, including email, phone, username as login ID, and password, OTP, magic links, etc. for authentication.
• Supports a wide range of identity providers, such as Google, Apple, and Azure Active Directory (AD).
• Supports biometric login on mobile, Passkeys, and Multi-Factor Authentication (MFA) such as SMS/email-based verification and authenticator apps with TOTP.
• A user management portal for password resets, account locking, scheduled deletion or anonymization, and user profile management.
• Single Sign-On (SSO) provides a single unified experience for your customers to log into multiple web/mobile apps, including Web2Web, Web2App, and App2App SSO.
• Enable SSO with SAML for your users to log into multiple web applications easily.
• Session management with Authgear Portal, and a pre-built setting page for users to control concurrent sessions.
• Customizable UI with a user-friendly low-code dashboard.
• Various security features such as audit logs, brute force protection, smart account lockout, password policy, etc.
• APIs for further integration and customization. For example, build your own custom login and sign-up pages from the ground up powered by the Authentication Flow API.

Most importantly, you can get started with Authgear for free.

Authgear contains the following high-level components:

• Client App SDKs - for developers to quickly implement authentication with Auth UI on your web and mobile applications. Check out Start Building for tutorials and API References.
• Auth UI - the default batteries-included UI for login, signup and the settings page. You can customize the style via the Portal, including the CSS and HTML of each page.
• Authentication Flow API - for developers to implement their own login, signup and reauthentication UI (e.g. a mobile native view); or to define a customized login, signup and reauth flow.
• Use Authgear as OpenID Connect Provider - for developers to use Authgear with other software that already supports OIDC login, you can use Authgear as an OpenID Connect Provider.

• Backend/API Integration - explains the common approach of using Access Tokens or Cookies (JWT or random string) to authenticate API or HTTP requests.
• Admin API - allows your backend to interact directly with Authgear for user management purposes.
• Events and Hooks - call an external web endpoint or use hosted TypeScript to customize the behaviour of Authgear, e.g. blocking certain types of sign-up, or calling an external endpoint on each login.
• User Import API - Import multiple users from another service to your project.
• Export User API - Export user data from Authgear into a CSV or ndjson file.
• Link OAuth Provider using Account Management API - Link an OAuth provider to a user's account without AuthUI.

• Authgear Portal - You can configure your projects, manage users, check out audit log, or customize the AuthUI. See the 5-minute quick start guide for Authgear Portal.
• Analytics Page - View reports of all users and active users over a specific time interval on the analytics page.

• Brute-force Protection - Set account Lockout Policy to safeguard a user account from brute-force login attempts.
• Bot Protection - Bot protection tools to block automated attackers.
• Fraud Protection - Detect and stop fraudulent traffic such as SMS pumping before it drives up your messaging costs.
• Password Strength - Learn how to set password strength and how the password strength is calculated.

• Biometric Login - Add biometric login to your application.
• Two-Factor Authentication (2FA) - Enable 2FA in your Authgear project.
• Email Magic Link Login - Allow users to log in without a password using a magic link.
• Passkeys Login - Set up passkey for your project.
• Social Login / Enterprise Login - Allow users to log in to your application using their existing account with a social media site or enterprise login provider.
