OTPs usually expire within 30 seconds to 10 minutes. It is physically impossible to manual-input or even script-input 1 million combinations before the code changes. : A popular collection of security-related lists

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.
