Question 1

What is a password strength checker?

Accepted Answer

A password strength checker is a free online tool that analyzes and tests the security of your passwords. It evaluates multiple factors including length, character variety, common patterns, and vulnerabilities to calculate a security score and estimate how long it would take hackers to crack your password. This helps you create stronger, more secure passwords.

Question 2

How does the password strength checker work?

Accepted Answer

Our password strength checker analyzes your password based on multiple security factors: length (12+ characters recommended), character variety including uppercase letters, lowercase letters, numbers, and special symbols, detection of common passwords and dictionary words, sequential patterns like abc or 123, and repeated characters. It calculates a security score from 0-100 and estimates crack time using modern brute force attack methods. All analysis happens in your browser for complete privacy.

Question 3

Is it safe to check my password here?

Accepted Answer

Yes, it's completely safe and private. All password analysis happens entirely in your web browser using JavaScript. Your password is never sent to any server, never stored anywhere, never logged, and never transmitted over the internet. Your passwords remain 100% private and secure on your device only.

Question 4

What makes a password strong?

Accepted Answer

A strong password should be at least 12-16 characters long and include a diverse mix of uppercase letters (A-Z), lowercase letters (a-z), numbers (0-9), and special characters like !@#$%^&*. Avoid common words, personal information, sequential patterns such as abc or 123, repeated characters like aaa or 111, and dictionary words. Our checker evaluates all these factors and provides specific actionable feedback to improve your password.

Question 5

How long does it take to crack a password?

Accepted Answer

Crack time varies dramatically based on password complexity. A weak 6-character password with only lowercase letters can be cracked instantly or within seconds. An 8-character password with mixed characters might take hours or days. A strong 16-character password with uppercase, lowercase, numbers, and symbols would take centuries or longer to crack using modern GPU-based brute force attacks. Our tool estimates crack time based on current hacking capabilities.

Question 6

What is a good password strength score?

Accepted Answer

Password strength scores range from 0-100. A score of 0-40 is considered weak and easily crackable. 41-60 is moderate but still vulnerable. 61-80 is strong and secure for most accounts. 81-100 is very strong and recommended for important accounts like banking, email, and work systems. Aim for at least 70+ for good security.

Question 7

Can I generate a strong password with this tool?

Accepted Answer

Yes! Click the 'Generate Strong Password' button to instantly create a secure 16-character password that includes uppercase letters, lowercase letters, numbers, and special characters. The generated passwords are cryptographically secure and score very high on the strength meter. You can generate multiple suggestions and copy them with one click.

Question 8

Why does my password show as weak?

Accepted Answer

Passwords show as weak for several common reasons: too short (under 12 characters), missing character types such as no uppercase letters, numbers, or special symbols, containing common words or patterns found in password lists, having sequential characters like abc or 123, having repeated characters like aaa or 111, or being similar to commonly used passwords. Check the detailed feedback section for specific suggestions to strengthen your password.
