Amazon, of all places, had this defect in their login flow for the longest time which was only recently fixed. It was so bad that when you were waiting for an SMS code, after you received it and autofilled it in iOS, their website and app would automatically submit the input, and so hitting submit on your keyboard would cause the backend to reprocess the code a second time, invalidating your login. It was obvious someone slapped the implementation together and it was so embarrassing. Yet, I’m still nonplussed that we keep screwing up forms.
