Add IP Fraud Scoring to Your Auth Flow

Credential stuffing bots hit login endpoints at thousands of requests per minute, rotating through IP addresses as they go. By the time your rate limiter reacts, the damage is done. An IP fraud score check sits before your auth logic, scores each IP from 0 to 100 and lets you decide whether to allow, challenge, or block. This tutorial adds that check to a Node.js/Express and Python/Flask login route. You'll also get the cURL version for testing. The whole thing takes about 30 minutes to wire up.
