Frequently Asked Questions

How secure is this password generator?

Our password generator uses the Web Crypto API (window.crypto.getRandomValues), which is cryptographically secure. Passwords are generated entirely in your browser — nothing is sent to any server.

What makes a password strong?

A strong password is at least 16 characters long and uses a mix of uppercase letters, lowercase letters, numbers, and special symbols. Avoid dictionary words or personal information.

Can I use these passwords for all my accounts?

Yes, but you should use a unique password for every account. Consider using a password manager like Bitwarden or KeePass to store them securely.

Is my generated password stored anywhere?

No. All password generation happens in your browser using JavaScript. We do not transmit, log, or store any generated passwords. The history feature uses your browser's localStorage only.

What is the maximum password length I can generate?

You can generate passwords up to 128 characters long. For most accounts, 16–32 characters provides excellent security.

Why should I avoid using dictionary words in my passwords?

Dictionary words are vulnerable to dictionary attacks, where hackers use automated tools to guess common words and phrases. A random combination of characters is mathematically much harder to guess.

How often should I change my passwords?

You only need to change your password if you suspect it has been compromised or if a service you use has experienced a data breach. Regularly changing strong passwords can actually lead to weaker password habits.

Do I need to include symbols to make a password secure?

While symbols increase complexity, length is the most important factor in password security. A very long password (like a passphrase) with just letters and numbers can be more secure than a short one with symbols.

What happens if I forget a generated password?

Since our tool does not store your passwords on any server, we cannot recover them for you. You should immediately save any generated passwords in a secure password manager.

Is it safe to generate passwords on a public computer?

No, it is not recommended. Even though our tool is secure and client-side, a public computer might have malware, keyloggers, or malicious extensions installed that could intercept your generated password.
