Frequently Asked Questions

The passwords are generated using cryptographically secure random number generation. With all options enabled (uppercase, numbers, symbols) and maximum length (64 characters), the passwords are extremely strong and resistant to brute-force attacks.

All passwords are stored locally in your browser's local storage. No data is sent to external servers, ensuring maximum privacy. However, this means passwords are only available on the device and browser where they were saved.

A strong password combines length (at least 12+ characters recommended), variety (uppercase, lowercase, numbers, and special characters), and randomness (no dictionary words or predictable patterns). Our generator creates passwords meeting all these criteria.

What Is a Secure Password Generator?

A secure password generator creates strong, random passwords that are very hard to guess or crack. Choose the length and character types — the password is generated in your browser and never sent anywhere.
