  1. 01Pick the length (anything from 6 to 128 characters).
  2. 02Toggle character sets — uppercase, lowercase, digits, symbols.
  3. 03Optionally enable “avoid ambiguous” to drop look-alikes such as O / 0 / l / 1.
  4. 04Click Regenerate for a fresh batch of five candidates.

FAQ

How is randomness sourced?
Via window.crypto.getRandomValues, the browser's CSPRNG. Each character is drawn uniformly from the chosen pool.
What entropy is enough?
60 bits is fine for everyday accounts; 80+ bits is recommended for high-value secrets such as encryption keys or admin passwords.
