How to generate a random password with chosen character classes

1. Pick the length

   "Length" defaults to 16 and accepts 6–128. 12+ is the modern baseline for human passwords; 20+ for anything machine-only (like API tokens you store in a vault, not type).

2. Enable the classes you need

   Toggle "Uppercase", "Lowercase", "Digits", and "Symbols". Disabling a class shrinks the pool — disabling Symbols turns the output into something that passes most password-input forms; enabling all four maximises entropy.

3. Press Run

   Result returns a single `password`. Each character is drawn from the union of enabled classes using `Math.random()` — fine for personal use, but NOT cryptographically secure. For server-side secrets, generate with `crypto.randomBytes` on the backend.

4. Storage and reuse

   Save the output in a password manager — never in a plain text file or a chat message you keep. Don't reuse this password across sites; the whole point of generating fresh strings per site is to make breaches contained.
