How to Use the Password Generator

Set length (8–64), choose character types (uppercase, lowercase, numbers, symbols), optionally exclude ambiguous characters (l, 1, O, 0, I). Click generate or press refresh. Copy with one click.

Password Generator Formula

Entropy = log2(charset_size^length); Strength = base(length) + 10 per char type − 10 if <12 chars

Example Calculation

Length 16, all character types:

Charset size ≈ 95; Entropy = log2(95^16) ≈ 105 bits

Very Strong password; 105 bits entropy

100% client-side using window.crypto.getRandomValues() — the most secure source of randomness in browsers. Your password is never sent to any server. You can verify by disconnecting your internet and the tool still works.
