// overview
PasswordStrength injects a real-time strength meter below every password input field, on any website. As you type, a color-coded bar and label (Weak / Fair / Strong / Very Strong) update instantly. Actionable hints tell you exactly what to add — uppercase letters, numbers, or special characters — to strengthen your password before you submit.

The strength bar and label update on every keystroke. You see your password's strength before you commit to it.
4-Level Scoring
