How strong are the generated passwords?

Each password is generated using cryptographically secure random number generation (CSPRNG), providing maximum entropy for security. Our 16-character passwords offer approximately 128 bits of entropy.

Are my passwords stored or logged?

No! All password generation happens locally in your browser. We never store, transmit, or log any passwords. Your generated passwords disappear when you close the page.

What makes a password strong?

Strong passwords use a mix of uppercase letters, lowercase letters, numbers, and symbols. Our 16-character passwords provide 128+ bits of entropy, making them virtually uncrackable by brute force.

16 characters is considered the gold standard for password security. At this length with full character set usage, passwords are virtually impossible to crack with current technology.

Should I remember these passwords?

No! These strong passwords are designed to be stored in a password manager. They're too complex to memorize but provide maximum security when stored properly.

Can I customize the password length?

Yes! Use our Password Generator Pro to create passwords of any length from 8 to 128 characters with custom character options.

How often should I change my passwords?

Modern security guidance suggests using strong unique passwords for each site and only changing them if there's a suspected breach. Our generator helps create unique passwords for every account.
