Frequently Asked Questions
Is this password generator secure?
Yes. This tool uses the Web Crypto API (crypto.getRandomValues()) which provides cryptographically strong random values. Passwords are generated entirely in your browser and never sent to any server.
What makes a strong password?
A strong password is at least 16 characters long and includes a mix of uppercase letters, lowercase letters, numbers, and symbols. The more diverse the character set and the longer the password, the harder it is to crack.
Should I use a different password for every account?
Absolutely. Reusing passwords across multiple accounts means that if one account is compromised, all your other accounts using the same password are also at risk. Use a password manager to keep track of unique passwords for each account.
