Assess Your Password Security: Strength Checker

In an age where digital security is paramount, creating strong, unique passwords is your first line of defense. Our Password Strength Checker helps you evaluate how robust your password is by analyzing it against several common criteria for strength, including a check against a list of very common passwords.

🛡️ How to Use the Checker

Using the Password Strength Checker is very straightforward:

1. Enter Your Password: Type the password you want to check into the input field. For your privacy, you can toggle the visibility of the password using the eye icon.
2. View Instant Feedback: As you type, the calculator will immediately assess your password and display:
   • A strength level (e.g., Very Weak, Weak, Fair, Strong, Very Strong).
   • A colored progress bar visually representing the score.
   • Specific feedback and suggestions for improvement. If your password is on a list of common weak passwords, this will be highlighted.

There's no "submit" button; the analysis is live and updates with each character you type or delete.

🔑 Criteria for Password Strength

This checker evaluates passwords based on several common factors:

• Common Password Check: The tool first checks if the entered password is on a list of very common and easily compromised passwords (e.g., "password", "123456"). If it is, the password will be rated as "Very Weak" regardless of other criteria.
• Length: Longer passwords are generally more secure. A common recommendation is at least 12-16 characters.
• Uppercase Letters (A-Z): Including capital letters increases complexity.
• Lowercase Letters (a-z): Using lowercase letters is standard.
• Numbers (0-9): Adding digits enhances strength.
• Symbols (!@#$%^&*, etc.): Incorporating special characters significantly boosts password complexity and resistance to brute-force attacks.

The checker assigns a score based on these criteria (unless it's a common password) and then translates that score into a qualitative strength level. The feedback provided aims to guide you in creating a more secure password by highlighting missing elements or common pitfalls.

💡 Frequently Asked Questions (FAQ)

What makes a password strong?

A strong password is long (12+ characters), complex (a mix of uppercase letters, lowercase letters, numbers, and symbols), unique (not used for other accounts), and unpredictable (not based on personal information or common words).

Should I use a password manager?

Yes, it's highly recommended. A password manager can generate and securely store unique, complex passwords for all your accounts, so you only need to remember one strong master password. This is the best practice for modern digital security.

Is it safe to enter my password here?

The password checking happens entirely within your browser. The password you enter is not sent to our servers or stored anywhere. However, as a general security practice, it's always best to check variations of your sensitive passwords rather than the exact ones on any public website.
