The risk of a 6-digit OTP being guessed depends entirely on how many attempts the system allows before the token expires or changes. Number of Allowed Attempts Probability of Guessing the OTP Risk Level 1 in 1,000,000 (0.0001%) Extremely Low 3 Attempts 3 in 1,000,000 (0.0003%) 10 Attempts 1 in 100,000 (0.001%) 1,000 Attempts 1 in 1,000 (0.1%) Unlimited 100% (Guaranteed success)
While an exhaustive list covers every possible OTP, it is rarely necessary in real attacks because rate limiting, lockout policies, and short OTP validity windows make such brute force impractical. Instead, security testers often use smarter, smaller wordlists that focus on high-probability codes. 6 digit otp wordlist
In the modern digital landscape, six-digit one-time passwords (OTPs) have become the de facto standard for two-factor authentication (2FA), transaction verification, and account recovery. From online banking to social media logins, these six-digit codes serve as a critical second layer of security. However, a growing niche of security enthusiasts, penetration testers, and unfortunately, malicious actors have shown increasing interest in something called a – a precompiled collection of potential six-digit codes used for brute-force attacks or testing.

Yes, many security research sites and GitHub repositories host such lists (e.g., “common-6-digit-pins.txt”). However, verify their origin and ensure you have legal right to use them. Never download from untrusted sources – they may contain malware or be illegally obtained.
Block or temporarily freeze accounts after 3 to 5 incorrect OTP attempts. Rate limiting should be applied globally, per IP address, and per specific user account to prevent distributed attacks. 2. Set Aggressive Expiration Windows
