Frequently Asked Questions
A **strong password** is long (12+ characters), uses a mix of character types (uppercase, lowercase, numbers, and symbols), and avoids common dictionary words, personal information, or repetitive patterns.
It’s based on **entropy** (the mathematical measure of randomness). We calculate the total number of possible combinations (keyspace) for your password and divide it by a theoretical attack rate (e.g., billions of guesses per second by a high-end GPU cluster). The result is an estimated time, which is for demonstrative purposes and assumes a worst-case scenario attack.
Absolutely not.

About Security Checkup
We believe in digital safety through awareness. The **Security Checkup** tool was created to provide a simple, transparent way for anyone to assess the robustness of their passwords. Our goal is to educate users on the principles of **password entropy** and complexity.
The cracking time calculation is performed entirely client-side (in your browser), meaning your password is never transmitted over the internet, ensuring maximum privacy and security during your check. We are committed to promoting strong, unique passwords across all your online accounts.
