What is a Password Strength Checker?
A password strength checker evaluates a candidate password and gives feedback...
- 🔹 Length — longer is stronger (≥12–16 characters)
- 🔹 Character variety — mix uppercase, lowercase, numbers, symbols
- 🔹 Entropy estimate
- 🔹 Dictionary & breach checks
- 🔹 Pattern detection
