Since each digit in a 6-digit code can be any number from 0 to 9, the total number of unique combinations is calculated as 10610 to the sixth power

Incident responders may compare logs of attempted logins against known wordlists to identify patterns of attack or credential stuffing.

Discuss the OTP security.

Attackers or testers often use rather than full lists, prioritizing codes that users or systems are more likely to generate:

The math behind a 6-digit numerical code is straightforward: 10 (numbers 0 through 9) Length: 6 digits Total permutations: possible combinations

TOTP algorithms (RFC 6238) derive the OTP from the current Unix time divided by a time step (usually 30 seconds). $$OTP = Truncate(HMAC(K, T))$$ An advanced wordlist generation strategy involves predicting the server's time drift. If an attacker knows the precise server time, they can generate a targeted wordlist containing only the valid OTPs for the current and adjacent time windows (e.g., T-1, T, T+1), reducing the candidate list from 1,000,000 to typically 3 values. 6 digit otp wordlist

Security auditors use a subset of an OTP wordlist to intentionally flood an authentication endpoint. If the server accepts more than a predefined number of guesses without blocking the traffic, the auditor flags a high-severity vulnerability.

Security researchers and penetration testers use OTP wordlists only on or have explicit written permission to test.

If you are building an application that relies on 6-digit OTPs via SMS, email, or authenticator apps, you must implement defensive layers to render wordlist attacks entirely obsolete. SecLists/Fuzzing/6-digits-000000-999999

Some attackers target low-security apps (e.g., gaming platforms, forums) that use 6-digit SMS OTPs. They trigger an OTP to the victim’s phone, then simultaneously run a wordlist to guess it before it expires (e.g., within 3–5 minutes).

(10 multiplied by itself 6 times). This results in exactly unique possibilities.
