Password Strength Checker
Not sure how resistant your password is to hacker attacks? Our tool uses advanced algorithms to analyze the complexity of your password in real-time. It estimates the time required to crack it (brute-force) and provides tips on how to make it more secure.
Frequently asked questions (FAQ)
Is the password I test sent over the internet?
Absolutely NOT. Security is our priority. The checking script runs 100% locally in your web browser (JavaScript). The password never leaves your device and is never stored anywhere.
What makes a password strong?
A strong password should be long (minimum 14 characters) and unpredictable. It should contain a combination of uppercase and lowercase letters, numbers, and special symbols, without using obvious dictionary words or personal data.
