How the Password Generator Works
The Password Generator is a robust security tool for creating strong, unique, and random passwords. It allows you to customize the length and character types (uppercase, lowercase, numbers, symbols) to meet any security requirement. All passwords are generated locally in your browser, ensuring they are never transmitted over the internet and remain completely private.
Here’s how to use the generator:
- Customize Your Password: Use the slider to set your desired password length. Use the switches to include or exclude uppercase letters, lowercase letters, numbers, and symbols.
- Generate a Password: Click the "Generate New" button to create a password based on your settings. The tool automatically ensures that characters from each selected set are included.
- Check Password Strength: The strength indicator provides immediate feedback on your password's security level (Weak, Medium, or Strong).
- Copy to Clipboard: Once you have a password you're happy with, click the "Copy Password" button. This action is secure and also adds the password (in a masked format) to your recent history for easy re-copying if needed.
- Use Presets: For convenience, you can use one of the quick presets like "High Security" or "Easy to Type" to instantly apply common settings.
Password Security Best Practices
1. Length is More Important Than Complexity
A longer password is significantly harder to crack than a short, complex one. Aim for at least 16 characters for important accounts. A 16-character password using only lowercase letters is exponentially stronger than an 8-character password with all character types.
2. Use a Unique Password for Every Account
The biggest security risk is password reuse. If one site you use is breached, hackers will try that same password on all your other accounts (email, banking, etc.). Generating a unique password for every single service is the most critical step you can take to protect your digital life.
3. Use a Password Manager
It is impossible to remember dozens of long, random passwords. Use a reputable password manager (like Bitwarden, 1Password, or your browser's built-in manager) to securely store and autofill your passwords. This is the only practical way to follow modern security advice.
Key Terms
Entropy
In the context of passwords, entropy is a measure of randomness or unpredictability, measured in "bits." A higher number of bits means the password is much harder to guess or brute-force. An entropy of 80 bits or higher is generally considered very secure.
Brute-Force Attack
A method used by hackers that involves systematically trying every possible combination of letters, numbers, and symbols until the correct password is found. Longer, more complex passwords dramatically increase the time required for a successful brute-force attack.
