Frequently Asked Questions
What makes a strong password?
A strong password is at least 12-16 characters long and includes a mix of uppercase letters, lowercase letters, numbers, and symbols. It should be unique and not contain personal information.
How often should I change my passwords?
Change passwords if you suspect a breach. Otherwise, focus on using unique, strong passwords for each account and enable two-factor authentication when available.
Should I use a password manager?
Yes, password managers are highly recommended. They store all your passwords securely and generate unique passwords for each account, so you only need to remember one master password.
Is this password generator secure?
Yes. Passwords are generated entirely in your browser using cryptographically secure randomness from the Web Crypto API (crypto.getRandomValues), not the predictable Math.random() function. No passwords are stored or transmitted. For maximum security, use this on a trusted device and network.
