What is this Tool?

The Password Strength Checker analyses your password's strength in real time and estimates how long it would take a modern computer to crack it using brute force. All analysis happens entirely in your browser — your password is never sent to any server or stored anywhere. This tool helps you understand what makes passwords weak or strong and gives specific actionable tips to improve your security.

Why This Matters

Frequently Asked Questions

Q: What makes a password strong?
A: Length (16+ characters), a mix of uppercase and lowercase letters, numbers, and special characters (!@#$%^&*), avoiding dictionary words, and not using personal information like your name or birthday.
Q: Should I use a password manager?
A: Absolutely yes. Password managers like Bitwarden (free), 1Password, or Dashlane generate and store unique, strong passwords for every site. You only need to remember one master password. This is the single best thing you can do for your online security.
Q: Is it safe to type my password in this tool?
A: Yes. This tool runs entirely in your browser. Your password is never transmitted to any server. You can verify this by disconnecting from the internet and testing — the tool still works perfectly.
Q: What is a passphrase?
A: A passphrase is a string of random words (e.g., 'correct horse battery staple') that is easier to remember than a random string of characters but equally or more secure due to its length. 4-5 random words create an extremely strong password.
💡 Pro Tip: The #1 rule of password security: never reuse passwords across multiple sites. If one site gets hacked and your password is exposed, attackers will immediately try that same password on every major website. Use a unique password for every account.
