Authentication
Proving you are who you say you are — login systems.
What is Authentication?
Authentication is the process of verifying a user's identity. Email + password, Google login, magic links — these are all authentication methods. Building auth from scratch is complex; tools like Supabase Auth and Clerk handle it for you.
Never try to build your own authentication system. The security risks are enormous, and services like Supabase Auth handle password hashing, session management, and account recovery automatically.
In Vibe Coding
Lovable integrates with Supabase Auth for login systems. In Cursor, you'll use Supabase Auth or Clerk. Never try to build authentication from scratch in vibe coding — the security risks are too high.
Example
For example: You add a login page to your app. Users can sign up with email + password, or click "Sign in with Google." Behind the scenes, Supabase Auth handles password hashing, session management, and account recovery.
