1. Head over to the API builder in Xano.
2. Set up a new API endpoint for user login.
3. In this API, add the necessary fields, like email and password.
4. Use the Authentication function block to check the user's credentials.
5. If everything checks out, you can return a session token.

• After verifying the user's credentials, generate a session token or grab an existing one.
• Store the session details, like session ID and user ID, in a sessions table in the Xano database.
• You can also add extra info like session expiry time.

1. Use the Set-Cookie HTTP header to set a cookie for the session token.
2. Define attributes like HttpOnly, Secure, and SameSite for the cookie to keep things secure.
3. Example of setting a cookie:
   ```http
   Set-Cookie: sessionToken=; HttpOnly; Secure; SameSite=Strict
   ```

1. Create a middleware or a function to validate the session.
2. Get the session token from the cookie.
3. Check the session token against the sessions table in the database.
4. Make sure the session is still valid and hasn't expired.
5. Retrieve the associated user info.

• Add logic to check when the session token expires.
• If the session is about to expire or has expired, ask the user to log in again.
• Or, you can create a session renewal endpoint to extend the session's validity and update the expiry time in the database.

1. Create an API endpoint for user logout.
2. Invalidate the session token by removing it from the sessions table.
3. Clear the session cookie by setting its expiry date to a past date:
   ```http
   Set-Cookie: sessionToken=; Expires=Thu, 01 Jan 1970 00:00:00 GMT; HttpOnly; Secure; SameSite=Strict
   ```

• Use HTTPS to encrypt data between the client and the server.
• Implement IP and User-Agent checks to add an extra layer of security to sessions.
• Regularly audit and monitor sessions for any suspicious activities.

All these steps together can help you manage sessions and cookies in Xano, ensuring a secure and efficient user authentication system.
