Backenly includes a complete user authentication system for every project. End-users of your application can register, sign in, and authenticate API requests using JWT tokens. The authentication system is isolated per project — each project has its own user database and JWT secret, completely separate from all other projects.
How it works
When your project is created, Backenly automatically provisions a users table in your project's workspace, sets up sign-up and sign-in API endpoints, configures JWT token generation and validation, and applies row-level security so each user can only access their own data. Your frontend can call the auth endpoints directly or use the Backenly SDK to handle authentication flows.
Why it matters
Authentication is one of the most complex and security-critical parts of any backend. Getting it wrong can expose user data or allow unauthorized access. Backenly implements authentication correctly by default — using industry-standard JWT tokens, bcrypt password hashing, and proper session management — so you never have to worry about auth security.
What you get
Sign-up and sign-in endpoints
Backenly generates /auth/signup and /auth/signin endpoints for your project automatically. Users can register with email and password and receive JWT tokens for subsequent authenticated requests.
JWT-based sessions
Authentication uses short-lived JWT access tokens and longer-lived refresh tokens. Tokens are signed with a project-specific secret, completely isolated from other projects.
Row-level security integration
Authentication integrates with database row-level security — authenticated users can only read and write their own data, enforced at the database level, not just the API layer.
User management via SDK
The Backenly JavaScript SDK includes auth helpers for sign-up, sign-in, sign-out, and token refresh — so your frontend can handle authentication with a few lines of code.
Common questions
Is authentication included on the free plan?
Yes. Authentication is included on all plans, including the free plan. There are no auth-specific limits or additional charges.
Can I customize the authentication flow?
You can configure auth settings at the project level. Custom roles, permission policies, and access control rules can be set through the Backenly dashboard or AI commands.
Does Backenly support OAuth or social login?
Backenly currently supports email/password authentication. OAuth and social login integrations are on the roadmap.
