Frequently Asked Questions

Q. What password length is best?

We recommend at least 16 characters with a mix of types (e.g., K9$mPq7@vL2bN8wR). Complexity increases exponentially with length.

Q. Are passphrases secure?

Yes. Selecting 6 random words from a list of ~7,776 provides about 77 bits of entropy, making them easy to remember and resistant to brute-force.

Q. Does this tool store generated passwords?

No. All generation happens locally via the browser's Web Crypto API. No data is sent to or recorded on our servers.

Q. Are there characters I should avoid?

Some sites may reject symbols like $, &, ', <, > due to escaping issues. You can exclude them in the options if necessary.

Q. Should I change my passwords periodically?

Per NIST guidelines (2017+), it is more important to use strong, unique passwords and 2FA, changing them only if a breach is suspected.
