Frequently Asked Questions
Is it safe to use an online password strength checker?
Yes, our password strength checker is completely safe to use. All password analysis happens locally in your web browser using JavaScript - no password data is ever transmitted to our servers or stored anywhere. Your passwords remain completely private and secure throughout the testing process.
What makes a password strong according to your checker?
Our algorithm evaluates multiple factors: minimum 8 characters length (12+ recommended), inclusion of uppercase and lowercase letters, numbers, and special characters, uniqueness of character combinations, absence from common password lists, and lack of predictable patterns like sequential characters or repetition.
How often should I check my password strength?
We recommend checking password strength whenever you create new passwords or update existing ones. Additionally, it's good practice to review and strengthen your passwords every 3-6 months, especially for critical accounts like banking, email, and work-related systems.
Can this tool help prevent data breaches?
While no single tool can guarantee complete protection, using strong passwords significantly reduces your vulnerability to common attack methods like brute force attacks, dictionary attacks, and credential stuffing. Strong passwords are your first line of defense against unauthorized access.
What should I do if my password is rated as weak?
If your password is rated as weak, follow our specific recommendations: increase length to at least 12 characters, add missing character types (uppercase, lowercase, numbers, symbols), avoid common words or patterns, and consider using a passphrase approach with multiple words separated by symbols.
