Frequently Asked Questions
Everything you need to know about password security and generation
How secure are the passwords generated by this tool?
Our password generator uses the Web Crypto API's cryptographically secure random number generator, making the passwords truly random and unpredictable. This is the same level of security used by professional security applications and meets military-grade standards.
Are my generated passwords stored anywhere?
No, absolutely not. All password generation happens locally in your browser using JavaScript. No passwords are ever sent to our servers or stored anywhere. Your privacy and security are our top priorities.
What makes a password strong and secure?
A strong password typically has 12+ characters, includes a mix of uppercase and lowercase letters, numbers, and special characters, doesn't contain dictionary words or personal information, and has high entropy. Our strength meter evaluates all these factors using industry standards.
How often should I change my passwords?
For most accounts, changing passwords every 6-12 months is sufficient. However, change passwords immediately if you suspect a breach, after any security incident, or if the password appears in data breach lists. Always use unique passwords for different accounts.
Should I use a password manager with generated passwords?
Yes! Password managers are essential for modern security. They generate, store, and auto-fill unique passwords for all your accounts, making it easy to maintain good security practices. Use our generator with your password manager for maximum security.
What is password entropy and why does it matter?
Password entropy measures the randomness and unpredictability of a password. Higher entropy means more possible combinations, making brute force attacks exponentially more difficult. Our tool calculates entropy to help you understand password strength.
