How We Calculate the Data

Web Crypto API

Unlike `Math.random()`, we use cryptographically secure random number generation natively supported by all modern browsers.

Entropy Calculation

We measure the strength of your password in 'bits of entropy', calculating precisely how long a supercomputer would take to brute force it.

Time to Crack

Assuming an attacker can guess 100 Trillion combinations per second, we provide realistic estimates for password resilience.

QR Translation

Your seed phrase is converted into a standard 2D barcode format locally, ready to be safely imported into offline hardware wallets.
