8 Digit Password Wordlist

Approach

Sequential Generation: The simplest way is to start from 00000001 and end at 99999999, saving each number as you go.
Random Generation: Another approach is to generate random 8-digit numbers and save them to a list, ensuring there are no duplicates.

Types and composition

Numeric-only (digits 0–9): 10^8 = 100,000,000 possible combinations.
Alphanumeric (lowercase + digits): typically 36^8 ≈ 2.8×10^12.
Alphanumeric mixed case + symbols: far larger (62^8 for letters+digits ≈ 2.18×10^14; adding symbols multiplies further).
Pattern-based lists: common formats like 4 letters + 4 digits, year+name, leet substitutions (e→3, a→4), repeated characters, keyboard walks.
Human-derived lists: compiled from breached passwords, leaked datasets, or commonly used password patterns (e.g., “password”, “qwerty”, names + 2–4 digits).
Hybrid/combinatorial lists: generate by combining dictionaries (words, names) with digit suffixes/prefixes and transformations.

Downloading Pre-Made Wordlists (Proceed with Caution)

Public wordlists (e.g., rockyou.txt, SecLists) contain many 8-digit passwords. You can filter them: 8 Digit Password Wordlist

The Math: The "Keyspace" Problem

To understand why 8-digit wordlists are so effective, you have to understand the math of combinations, known in cybersecurity as the "keyspace."

If you have a purely numeric password (a PIN code), an 8-digit password has a keyspace of $10^8$. That is 100,000,000 combinations (from 00000000 to 99999999). Approach

That sounds like a lot, right? One hundred million.

But to a modern GPU (Graphics Processing Unit), which is what hackers use to crack passwords, 100 million is a snack. A single high-end RTX 4090 graphics card can attempt billions of hashes per second, depending on the algorithm. A purely numeric 8-digit password can be cracked in seconds, sometimes milliseconds.

3. Kwprocessor (Keyboard Walk Generator)

Creates 8-character patterns from keyboard paths (e.g., qazwsxedc trimmed to 8).

Practical use cases

Penetration testing and red team engagements (authorized only).
Password auditing to evaluate organizational password strength.
Forensics and legitimate account recovery when authorized.
Research into password habits and entropy.

Common sources (for authorized testing):

SecLists (GitHub)
Weakpass (weakpass.com)
RockYou (from breach data – use only in lab environments)

🔐 Never reuse real passwords from breaches for your personal accounts. These lists are for defensive security testing only.

C. Year + Significant Number

Often passwords are a year followed by a 4-digit PIN (e.g., 19901234 or 20231111).
