Block IP addresses or specific user accounts after a small number of failed attempts.
Sometimes, developers store the plain-text OTP in a database column called temp_code and forget to delete it. If you download a breached database (found on dark web forums), you might get a list of valid OTPs mapped to user IDs. That is not a "wordlist" of guesses; it is a credential stuffing list.
A standard 6-digit OTP consists entirely of numeric digits ranging from 0 to 9 . Because each of the 6 positions can hold any of the 10 possible digits, the total number of unique combinations is calculated using fundamental permutation principles:

The allure of a "6-digit OTP wordlist" is a mirage. While the total number of combinations is small enough to fit on a floppy disk, the security protocols surrounding OTPs—specifically time limits and attempt restrictions—render the list practically impotent. The strength of the 6-digit OTP lies not in the secrecy of the numbers, but in the strict parameters governing their use. As authentication methods evolve towards biometrics and hardware keys, the 6-digit code remains a reliable security layer, proving that in cybersecurity, the value of a key is determined not just by its shape, but by the lock it fits into.
