Frequently Asked Questions
How does the password strength checker work?
It analyzes your password using entropy calculation, pattern detection, common password databases, and character diversity to give you an accurate strength rating.
Is my password sent to any server?
No. All analysis happens entirely in your browser. Your password is never transmitted anywhere, ensuring complete privacy.
What is password entropy?
Entropy measures the randomness of a password in bits. Higher entropy means the password is harder to crack. A password with 60+ bits of entropy is considered strong.
What makes a password "Very Strong"?
A very strong password typically has 16+ characters, includes uppercase, lowercase, numbers, and symbols, has no common patterns, and achieves 80+ bits of entropy.
Should I use the same password for multiple accounts?
Never. Use unique passwords for each account. Consider using a password manager to keep track of them securely.
