Password Strength Checker

How to Check and Create Secure Passwords

In an era of constant digital threats, a strong, unique password is your first line of defense. This tool is designed not only to analyze the security of your existing passwords but also to help you generate new, exceptionally strong ones.

Using the Password Strength Analyzer

The analyzer gives you instant, actionable feedback on your password's security. For your privacy, all analysis is performed locally in your browser—your passwords are never sent to our servers.

1. Enter Your Password: Simply type your password into the input field. As you type, the tool will evaluate it in real-time.
2. Review the Strength Meter: The colored bar provides an immediate visual assessment, from "Very Weak" to "Very Strong."
3. Check the Criteria: Below the meter, a checklist of essential security criteria will update. A green checkmark indicates your password meets that standard. This includes checks for length, character types (uppercase, lowercase, numbers, symbols), and most importantly, a data breach check. This feature securely checks if your password has been exposed in known public data breaches without ever revealing your password.

Using the Strong Password Generator

The easiest way to create a secure password is to have a random one generated for you. A good password should be impossible for a human to guess and difficult for a computer to crack.

1. Set the Length: Use the slider to select your desired password length. For optimal security, we recommend at least 16 characters.
2. Choose Character Types: Ensure the "Include Numbers" and "Include Symbols" boxes are checked. Including a mix of all character types exponentially increases the password's complexity and strength.
3. Generate & Copy: Click the "Generate & Check" button. A new, random password will be created and automatically tested in the analyzer. Once you have a password you're happy with, click "Copy Password" to safely copy it to your clipboard for use.
