Password Strength Guide
Password Strength Checker Guide: What Makes a Strong Password?
A password strength checker is useful when it catches patterns humans miss. It should help you avoid short, reused, obvious, or predictable passwords before they become account risk.
What A Checker Can Catch
- Passwords that are too short.
- Common words, product names, and obvious terms.
- Repeated characters like aaa or 111.
- Keyboard walks and sequences like qwer or 1234.
- Low character variety when the password is short.
What It Cannot Promise
A strength checker cannot know whether you reused the password, shared it, saved it in an unsafe place, or put personal information inside it. Treat the score as a warning system, not a guarantee.
The Better Default
For most accounts, the safest habit is unique passwords stored in a manager. For passwords you must type, generate a random passphrase with enough words to make guessing unrealistic.
Stronger pattern
random-word-random-word-random-word-random-word-random-word-random-word
Randomness and length matter more than familiar substitutions like a for @ or o for 0.
Use A Local Checker
Passlock's checker runs in the browser and builds a safe report that does not include the password. Use it to catch weak patterns, then store the final password somewhere you can trust.
Check A Password Locally
