How to Use the Password Generator

Our password generator creates strong, random passwords instantly. Adjust the length slider to set your desired password length (from 8 to 128 characters), select which character types to include, and click "Generate Password." The generated password appears in the dark display area at the top, where you can copy it to your clipboard with one click.

For maximum security, we recommend keeping all character types enabled and using a length of at least 16 characters. The strength indicator below the generate button gives you instant feedback on how strong your password is.

Why You Need Strong Passwords

In today's digital world, strong passwords are your first line of defense against unauthorized access to your accounts and personal information. Weak passwords are the leading cause of data breaches, and cybercriminals use sophisticated tools that can try billions of password combinations per second.

According to cybersecurity research, over 80% of data breaches involve weak or stolen passwords. Using a random password generator eliminates the human tendency to create predictable passwords based on personal information, dictionary words, or simple patterns.

What Makes a Password Strong?

A strong password has several key characteristics:

  • Length: Longer passwords are exponentially harder to crack. A 12-character password has approximately 95^12 (over 540 trillion trillion) possible combinations when using all character types.
  • Randomness: Truly random passwords have no patterns, dictionary words, or personal information that attackers could guess or infer.
  • Character variety: Using all four character types (uppercase, lowercase, numbers, symbols) maximizes the number of possible combinations.
  • Uniqueness: Each account should have its own unique password. Reusing passwords means that one breach can compromise multiple accounts.

Password Security Best Practices

Use a Password Manager

With unique, complex passwords for every account, it is impossible to remember them all. A password manager securely stores and auto-fills your passwords, making it practical to use strong, unique passwords everywhere. Popular options include Bitwarden, 1Password, and KeePass.

Enable Two-Factor Authentication

Even with strong passwords, two-factor authentication (2FA) adds an important extra layer of security. With 2FA enabled, accessing your account requires both your password and a second factor, such as a code from an authenticator app or a physical security key.

Check for Breaches

Regularly check if your accounts have been involved in data breaches using services like Have I Been Pwned. If an account has been compromised, change the password immediately and enable 2FA if available.

How Password Cracking Works

Understanding how attackers try to crack passwords helps illustrate why random generation is so important:

  • Brute force: Trying every possible combination. At 1 billion guesses per second, an 8-character password using all character types takes about 6.6 years to crack, while a 12-character password would take over 34,000 years.
  • Dictionary attacks: Trying common words and phrases. This is why dictionary words, even with number substitutions (like "p@ssw0rd"), are insecure.
  • Credential stuffing: Using passwords from previous breaches to try on other services. This is why unique passwords are essential.

Tips for Password Management

  • Never share passwords via email, text, or chat. Use a password manager's sharing feature when collaboration is needed.
  • Avoid writing passwords on sticky notes or in unencrypted files.
  • Use our generator to create a strong master password for your password manager, then let the manager handle everything else.
  • Consider using passphrases (random word combinations) for passwords you need to type manually — they can be both strong and memorable.

Frequently Asked Questions

Are the passwords generated truly random?
Yes. The generator uses the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. This is the same API used by password managers and security applications.
How long should my password be?
Security experts recommend a minimum of 12 characters for important accounts. For high-security applications, 16 or more characters are recommended. Longer passwords are exponentially harder to crack.
Should I include all character types?
Including uppercase letters, lowercase letters, numbers, and symbols creates the strongest passwords. Each additional character type dramatically increases the number of possible combinations, making the password harder to crack.
Is my generated password stored?
No. Passwords are generated entirely in your browser using client-side JavaScript. No passwords are ever sent to or stored on any server. Each generation is completely private.
How often should I change my password?
Current security best practices from NIST suggest changing passwords only when there is evidence of a breach, rather than on a fixed schedule. Using unique, strong passwords for each account is more important than frequent changes.
