How Weak Passwords Are Categorised
Weak passwords fall into predictable patterns that attackers exploit using dictionary attacks, credential stuffing, and brute force. This generator produces examples from four commonly studied categories.
Categories
- Dictionary — Common English words that appear in wordlists (sunshine, football, dragon). These are trivially cracked by any dictionary attack tool.
- Common — Passwords that consistently top global breach analysis reports (123456, password, abc123). Credential stuffing tools try these first.
- Keyboard — Patterns formed by adjacent keys on a QWERTY keyboard (qwerty, asdfghjkl, 1qaz2wsx). Visually random but completely predictable.
- Default — Credentials shipped with devices, routers, and software out of the box (admin, root, changeme). Often left unchanged.
Each entry includes a "weakness" description explaining why the password is insecure.
Frequently Asked Questions
To test password strength validators (zxcvbn, HIBP checks, policy rules), security training demos, breach simulation exercises, and to verify that your authentication system correctly rejects commonly known passwords.
A dictionary attack tries a predefined list of words and common passwords instead of brute-forcing every combination. Modern wordlists (like RockYou) contain billions of previously leaked passwords. Dictionary-category entries here are drawn from these lists.
Yes. These password patterns are well-documented in public breach analysis reports (e.g. from NordPass, Hive Systems, NCSC). They are shared here for educational and defensive testing purposes only.
Show participants that patterns like p@ssword or 1qaz2wsx appear verbatim in wordlists and offer no real security. Contrast with output from the strong Password Generator to demonstrate the difference.
Yes. Export to CSV or JSON. Each row includes the password, its category, and a plain-English description of why it is weak.
