1. Head over to the Endpoints section in Xano.
2. Click on Add API Endpoint and pick the POST method.
3. Give the endpoint a fitting name (like /auth/login).
4. In the Input settings, set up the required input fields (like email, password).

1. Set up logic to check user credentials against what's stored.
2. Use the Database > Query function to find a user with the given email.
3. Add a condition to compare the stored hashed password with the one the user provided.
4. If the credentials are wrong, return an appropriate error response.

1. Once the credentials are validated, generate an authentication token.
2. Use Xano's built-in Authentication > Generate Token function.
3. Define the token payload with necessary user data (like user ID, roles).

1. Create a response object that includes the generated token.
2. Set the response status to 200 OK.
3. Return the token and any additional user info if needed.

1. Go to the Middleware section in Xano.
2. Add a new middleware and name it something like VerifyAuthToken.
3. Use the Authentication > Verify Token function within the middleware.
4. If the token is invalid, return an unauthorized error response.
5. Attach this middleware to any endpoints that need authenticated access.

1. For each endpoint that needs user authentication, attach the VerifyAuthToken middleware.
2. Make sure the input schema of these endpoints includes the Authorization header.
3. This allows token verification before running the endpoint logic.

1. Create a new POST endpoint (like /auth/logout).
2. Attach the VerifyAuthToken middleware to make sure the user is authenticated.
3. Set up logic to invalidate the user's current token, if token revocation is supported.
4. Return a success message indicating the user has been logged out.

1. Set an appropriate expiration time for issued tokens during the generation step.
2. Implement a refresh token mechanism if continuous user sessions are needed.
3. Create a new POST endpoint (like /auth/refresh-token).
4. Attach the VerifyAuthToken middleware to verify the current token.
5. Issue a new token if the current one is near expiration, otherwise return an appropriate response.

Following these steps will help ensure efficient and secure handling of user authentication tokens in Xano.
