How the Password Strength Checker Works
The SimpleTaskTools Password Strength Checker analyzes your password security in real-time. Unlike other tools, all analysis happens locally in your browser - your password is never sent to any server, ensuring complete privacy.
What Makes a Strong Password?
A strong password should be at least 12 characters long and include a mix of uppercase letters, lowercase letters, numbers, and special characters. Avoid common words, sequential patterns (like 123 or abc), and personal information.
Time to Crack Estimates
Our tool estimates how long it would take to crack your password using modern GPU-based attacks (assuming 10 billion guesses per second). While these are estimates, they give you a realistic sense of your password security.
Privacy Guarantee
Your password never leaves your browser. All strength calculations happen locally using JavaScript, so you can safely test even your most sensitive passwords without any privacy concerns.
