Frequently Asked Questions

What length should my passwords be?

Use 16 or more characters for important accounts and 20-plus for crypto wallets and email. Longer passwords add entropy faster than symbol tricks.

Where should I store generated passwords?

Save them in a reputable password manager with a strong master passphrase and two-factor login. Never reuse one password across sites.

Is my data saved between sessions?

Data is stored locally in your browser using localStorage. Clearing your browser data will remove it. In Password Generator, entries stay in this browser only.

Can I lose my data?

Since data is stored locally, clearing browser data or using a different device will not carry over your information. In Password Generator, entries stay in this browser only.

Does this work offline?

Yes. Once loaded, generation uses Web Crypto entropy entirely offline. Create and copy passwords with no connection; nothing leaves your browser.

Is my data private?

Absolutely. Everything stays in your browser. No data is sent to any server or third party. In Password Generator, entries stay in this browser only.

How to Use

Set Length and Charset

Choose 12-32 characters with uppercase, numbers and symbols toggles.

How to Calculate

Characters draw from a secure random source across upper, lower, digits, and symbols. A 16-character full-set password carries about 105 bits of entropy; passphrases trade characters for memorable words at similar strength.
