While 6-digit OTP wordlists can be useful, there are several challenges and limitations to consider: A standard CPU can iterate through 1,000,000 integers
The information entropy ($E$) of a 6-digit OTP is: $$E = \log_2(10^6) \approx 19.93 \text bits.$$ While roughly 20 bits of entropy is sufficient to deter manual entry, it is computationally trivial for modern hardware. A standard CPU can iterate through 1,000,000 integers in milliseconds. Therefore, the security of OTP relies not on the complexity of the value, but on the temporal constraints of the validation window.
