In security testing, you would never use the full list on a live production system without explicit authorization. Instead, use a :
What is the formula to estimate how long it can take to guess an OTP?
Many users choose birthday patterns such as DDMMYY or MMDDYY . Security Context 6 digit otp wordlist
: The chance of guessing a 6-digit OTP on the first try is 1 in 1,000,000 .
(10 multiplied by itself 6 times). This results in exactly unique possibilities. In security testing, you would never use the
In the early days of two-factor authentication (2FA), poorly configured systems allowed attackers to try thousands of codes per second until they hit the right one. Today, relying on a 6-digit OTP wordlist for an unauthorized breach is highly impractical due to standard defensive engineering. 1. Rate Limiting and Account Lockouts
If your risk profile is high, consider moving away from 6-digit numerical codes: Security Context : The chance of guessing a
Python can generate a complete 6-digit wordlist in a matter of seconds. By using the .zfill(6) method, the script ensures that numbers under 100,000 retain their leading zeros.
Some weak custom OTP generators produce codes that follow patterns (e.g., sequential, timestamp-dependent, or seeded with predictable values). A wordlist of possible next codes can reveal such flaws.
