Wordlist — 6 Digit Otp

While these bypass the OTP entirely, having a wordlist helps during the brief window of interception if the OTP is sent via SMS.

| Countermeasure | Effect on Wordlist Attack | |----------------|---------------------------| | (e.g., 3 attempts per 30 seconds) | Renders full wordlist infeasible | | Account lockout after 5–10 failed OTP attempts | Blocks further tries for that user | | Short OTP validity (30–60 seconds) | Reduces brute-force window drastically | | CAPTCHA after N failures | Prevents automation | | Time-based OTP (TOTP) with 30-second windows | Even if code is guessed, it expires quickly | | Increasing delays (exponential backoff) | Slows down progressive guessing | | Monitor and block IPs making many attempts | Disables distributed brute-force | 6 digit otp wordlist

Without these, a 6-digit OTP wordlist is a serious threat. While these bypass the OTP entirely, having a
