hashcat -m 0 -a 3 hash.txt ?d?d?d?d?d?d No wordlist needed – mask attack is faster. Q1: Is downloading a 6 digit OTP wordlist free illegal? A: No – possessing the file is not illegal. Using it to attempt unauthorized access to a system you do not own or have explicit permission to test is illegal . Q2: Can I use a 6-digit wordlist on Instagram/Gmail/Bank of America? A: Technically, you can try. But all major platforms have rate limiting, CAPTCHA, and account lockouts. You will not succeed, and your IP will be blacklisted. Q3: What’s the file size of a full 6-digit wordlist? A: Approximately 7.6 MB as plain text. Zipped, it’s about 1.2 MB. Q4: Are there any pre-made “top 100” OTP wordlists? A: Yes. Search GitHub for “common pins” or “top otp”. The SecLists project includes top-100-otp.txt . Conclusion: Use Knowledge, Not Just Lists Searching for a “6 digit OTP wordlist free” is a sign that you are curious about authentication security. That curiosity is valuable – but only if channeled ethically. The reality is that you rarely need a pre-made list. Generating one is trivial, and against modern systems, a raw brute-force attack with a full million-entry wordlist will almost always fail due to rate limiting.
A of just 10,000 common patterns (available in SecLists) will successfully crack 15-20% of poorly chosen 6-digit OTPs in a local offline attack. That’s much more efficient than trying all 1 million.
Introduction In the world of digital security, the six-digit One-Time Password (OTP) has become a universal standard. From Google Authenticator to SMS-based bank logins, the 6-digit code acts as the second layer of defense in two-factor authentication (2FA). But for security researchers and penetration testers, there exists a niche but critical question: Where can I find a 6 digit OTP wordlist free of charge, and is it even ethical to use one?
