How it works
- Your browser's Web Crypto API generates cryptographically secure random values — the same kind of source used for encryption keys, not a predictable pseudo-random function.
- Those random values are mapped onto the character sets you've enabled (uppercase, lowercase, numbers, symbols) to build the password character by character.
- An estimated strength label is calculated from the password's length and how many character types it draws from, using an entropy-based estimate.
- The password exists only in your browser's memory — copying it to your clipboard is the only place it goes.
