How does our offline password generator keep you secure?
Many online generators send your generated keys over the network, exposing them to traffic sniffers or server logs. OptiKit does not communicate with any external backend. It leverages the cryptographically secure pseudo-random number generator (CSPRNG) built right into modern browsers. That means your credentials are truly random, completely private, and never written to an external database.
Password Security Best Practices
- Never Re-use Passwords: Always generate a unique password for each online account. If one portal gets breached, your other accounts stay safe.
- Use a Password Manager: Since secure passwords are hard to remember, store them in a local or encrypted cloud manager (e.g. Bitwarden, 1Password).
- Prefer Passphrases for master keys: Use XKCD-style passphrases for accounts you type manually (such as computer logins or master database keys).

Frequently Asked Questions
No. The password generation is performed entirely on your device using the browser's built-in Web Crypto API. No data is sent over the internet, and your generated passwords never touch our servers.
