That’s exactly the kind of nightmare scenario that inspired us to create Prelude (https://prelude.so/ https://prelude.so/). Authentication flows are targeted by fraud like SMS pumping that leaves companies with super high bills that make no business sense.

On top of that, we let users set daily limits as an additional safety net, so surprises like this don’t happen.
