Password checker: analyze the security of your credentials
The security of your online accounts depends directly on the strength of your passwords. Modern brute force attacks can try billions of combinations per second. This checker lets you evaluate in real time how resistant your password is against these attacks, calculating entropy and estimated crack time.
The tool analyzes multiple factors: length, use of uppercase and lowercase, inclusion of numbers and special characters, and the presence of repetitive patterns. A 16-character mixed password has an astronomically larger search space than an 8-character letter-only password.
All evaluation is performed entirely in your browser. Your password never leaves your device or is transmitted to any external server, ensuring total privacy.
