The security analysis provides additional insights into how long it would take to crack your password.

Understanding Password Strength: Password strength is determined by several factors including length, character variety, and unpredictability. Longer passwords with a mix of uppercase, lowercase, numbers, and special characters are significantly more secure. The tool evaluates these factors and provides a comprehensive strength rating from "Very Weak" to "Strong" with specific recommendations for improvement.

Security Best Practices: Always use unique passwords for different accounts, avoid common words or patterns, and consider using a password manager for generating and storing strong passwords. Regularly update your passwords, especially for critical accounts like banking and email. Enable two-factor authentication whenever possible for additional security layers.

Privacy and Security: Our tool operates entirely in your browser - your password is never transmitted to our servers or stored anywhere. All analysis happens locally, ensuring your password remains completely private and secure. This makes it safe to test any password, including your actual account passwords.
