1. Head over to the database section in your Xano dashboard.
2. Create a new table called Users with these columns:

• id (Auto-increment integer, Primary Key)
• email (String)
• password (String)

1. Feel free to add more columns if you need them, like username, role, etc.

1. Go to the API section and make a new API endpoint named register.
2. Under the "Input" tab, add fields for email and password.
3. In the "Function Stack", add these functions:
   • Validation: Add a validation function to check if email and password are provided.
   • Hashing: Use a hashing function to hash the password.
   • Database Insert: Insert the new user record into the Users table with the email and hashed password.
4. Customize responses based on success or failure, like "User registered successfully," "Email already exists," etc.

1. Create another API endpoint named login.
2. Under the "Input" tab, add fields for email and password.
3. In the "Function Stack", add these functions:
   • Validation: Add a validation function to check if email and password are provided.
   • Database Query: Retrieve the user record from the Users table where the email matches.
   • Password Verification: Verify the input password with the stored hashed password.
   • Token Generation: If passwords match, generate a JWT (JSON Web Token).
4. Customize responses based on success or failure, like "Login successful," "Invalid credentials," etc.

1. Create a new middleware for token verification.
2. Implement functions to:
   • Extract the token from the headers.
   • Verify the token's validity.
   • Identify and attach the user ID to the request context.
3. Apply this middleware to secured routes.

1. For any endpoints that should be secured, update the settings to apply the token middleware.
2. Add an access control functionality if needed, like role-based access.

1. Create a new API endpoint named profile.
2. Use the token middleware created in Step 4.
3. In the "Function Stack", add a function to retrieve and return user details from the Users table using the user ID from the token context.
4. Customize the response to return user-specific information.

1. Use tools like Postman or Insomnia to test the register and login endpoints to make sure they work as expected.
2. Test the token verification by accessing protected routes.

1. Set up error handling functions to catch and return meaningful error messages.
2. Implement logging for debugging and monitoring purposes.

1. Use Xano’s built-in documentation tools to generate API docs.
2. Make sure your documentation includes details about authentication, endpoints, and input/output formats.

Follow these structured steps to set up a custom authentication mechanism in Xano, ensuring it aligns with specific application requirements.
