Frequently asked questions

Do you store my password?
No. The checker posts only to compute the score and discards input immediately.
What score is considered strong?
Aim for 80+ with 12+ characters and multiple character sets.
What does the Password Strength Checker do?
Estimate password strength from length and character variety and receive practical improvement suggestions.
How should I interpret a Password Strength Checker result?
Read the displayed labels and validation messages together, then verify important findings against the original source. The result is a practical aid, not proof beyond the data it can inspect.
What can affect the Password Strength Checker result?
A meter cannot know every breach list, reuse pattern, service-side defense, or attacker strategy, so its score is guidance only.
