A 6-digit OTP typically expires in 30 to 120 seconds. Even with a botnet, you cannot realistically iterate through 500,000 combinations in 30 seconds over HTTP requests.
The keyspace is 1,000,000. A "wordlist" that covers all possibilities is simply a brute-force generator. To download a file containing every 6-digit number, you would need a file roughly 7 MB in size (each line: 6 digits + newline). That is trivial to generate, but useless without bypassing rate limits.
Conclusion: If you search for "6 digit OTP wordlist free" expecting to hack an Instagram account, you will fail. The defense is not the complexity of the code; it is the rate limiting and expiration. 6 digit otp wordlist free
After a certain number of failed attempts, the account may be locked for a specific period (e.g., 30 minutes) or until the user verifies their identity via another method.
Instead of using the full 1,000,000-line wordlist, professional testers use smart wordlists based on human psychology. Studies show that 6-digit OTPs are not random. The most common 6-digit codes are: A 6-digit OTP typically expires in 30 to 120 seconds
| Rank | Code | Reason | |------|--------|----------------------------------| | 1 | 123456 | Sequential pattern | | 2 | 111111 | Repeated digit | | 3 | 000000 | All zeros | | 4 | 123123 | Repeated pattern | | 5 | 112233 | Stepped pattern | | 6 | 789012 | End of row on keypad | | 7 | 654321 | Reverse sequential | | 8-20 | Birthdays (e.g., 010190) | MMDDYY format |
A focused wordlist 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. SecLists is the standard for penetration testing wordlists
To generate such a list yourself:
# Generate all MMDDYY combinations (birthdays)
for month in range(1,13):
for day in range(1,32):
for year in range(0,100):
print(f"month:02dday:02dyear:02d")
SecLists is the standard for penetration testing wordlists. It includes a file called six-digit-pin-codes.txt (often a subset or common patterns). You can find it at:
https://github.com/danielmiessler/SecLists/tree/master/Passwords
Note: This is not the full 1M list but a curated list of ~10,000 likely PINs (e.g., birthdays, repeating digits).
A 6-digit OTP is a type of one-time password that consists of six numeric characters. This code is usually generated randomly and is valid for a short period, often between 30 seconds to a few minutes. The purpose of a 6-digit OTP is to add an additional layer of security to the authentication process, making it more difficult for unauthorized users to gain access to sensitive information.
