Our tool analyzes multiple factors including password length, character diversity (uppercase, lowercase, numbers, symbols), entropy calculation, and common password patterns to provide a comprehensive strength score.
Yes, it's completely safe. All analysis is performed locally in your browser using JavaScript. Your password is never transmitted to our servers or stored anywhere, ensuring complete privacy and security.
A strong password typically has 12+ characters, includes uppercase and lowercase letters, numbers, and special characters, avoids common words or patterns, and has high entropy (randomness).
Password entropy measures the randomness and unpredictability of a password. Higher entropy means the password is harder to guess or crack. It's calculated based on the character set size and password length.
Change passwords immediately if there's a security breach, when leaving a job, or if you suspect compromise. For strong, unique passwords, changing every 6-12 months is generally sufficient. Focus on using unique passwords for each account.
